Steve's Virtual Yard Sale

From time to time I have some old junk to pass on as someone else's treasure.

So I list it here, and often elsewhere such as the Antique Radio Forum, Craigslist, or eBay, or cart it off to a NEARC antique radio meet or a ham-fest.

Philco 46-1209 chassis parts

My neighbor’s son wanted to bring his grandfather’s Philco 46-1209 radio back to life. We started to recap it, but his chassis had a toasted power transformer. I swapped my restored 46-1209 chassis for his, intending to restore it. I obtained a replacement power transformer from Gary at Playthings of the Past, but the chassis has sat on the shelf for a couple of years waiting for a round tuit. I’ve finally admitted that I’ll never get to it – I've got more interesting projects to do.

So, I’m offering the chassis (minus power transformer, no tubes) either free for local pickup or delivery to Radio L in Nashua NH in March, or parted out for $5 a part plus shipping from 01460. I don’t want to deal with shipping the whole chassis.

If someone is in need of a Philco part number 32-8248 (or 32-B248, as some sources have it) power transformer, 340-0-340V @70ma, 5V 2A, 6.3V 2.5A, 6.3V .6A, you can have it for $25.00 plus shipping from 01460. Priority Mail medium flat rate box is probably the best shipping option. This transformer was used in the Philco 46-1209, the 48-1264, and maybe the 48-1263 and others.

Here’s the crispy power transformer. Anyone up for rewinding it?

The loop antenna, dial glass, and the re-coned speaker are also available free for pickup.



Ground lead and tips for General Radio 1806-A AC probe

I made up a small run of ground leads for the AC probe of the General Radio 1806-A VTVM. I also have a small stock of screw-on probe tips that match the original General Radio tips, which were clearly OEM’d from Tektronix. Construction details are in this post in my blog, if you want to make your own.

IMG 6709.jpg


IMG 6712.jpg

Note that three of the ground leads  are missing the heat-shrink tubing on the connection to the minigator clip. Solder first, think later, what're ya gonna do :-(. First come get the ones with heat-shrink on both ends.

Price for ground clip: $5 each plus shipping from 01460. They'll fit in a small padded envelope, so they should be able to ship via USPS first class large envelope rate. I have ten available.

I don't expect to be overwhelmed with orders :-)

I also have fifteen Tektronix 206-0104 straight probe tips and fifteen Tektronix 206-0105 hooked probe tips. See photos below. Both fit the 1806-A AC probe.

Price for tips: $2 each plus shipping from 01460. If you don't want the box for the 206-0104 straight tip, it'll fit in a small padded envelope, as will the 206-0105 hook tip.

Tektronix "QuickStart Guide to 2400 Series Digial Oscilloscopes"

In one of the piles of junk from a lab cleanout I found a Tektronix “Operator’s Workbook” entitled "QuickStart Guide to 2400 Series Digial Oscilloscopes”. It says it’s part of the “Self-Study Series”, PN 070-7118-00.

IMG 4531.JPG

It’s a 6 x 9 inch spiral-bound book in excellent shape.

IMG 4532.JPG

It has hands-on exercises to teach you the ins and outs of these digital oscilloscopes. 

IMG 4534.jpg

It has a nice fold-out picture of a Tek 2430A scope.

IMG 4536.jpg

Unfortunately it depends on not only having a 2400-series oscilloscope, but also a special “QuickStart Training Lab” to provide the signals for the exercises.

IMG 4533.JPG

The back cover has the index.

I’m asking $5 plus media mail postage.

Micronta 22-201U VOM

IMG_3503

This is a nice little 20,000 ohms per volt VOM from Radio Shack. Unfortunately the shaft of the range switch broke, so its only good for parts. Maybe it can help repair another copy. The cosmetic condition is very good. Complete with owners manual and original box. No probes, though; I used them to make HV discharge sticks. The meter has pin jacks, not banana jacks.

IMG_3500

You can see that the wiper of the range switch broke off from the shaft. I tried heat-welding the Delrin back together but it didn't have enough strength to handle the spring tension from the wiper.

IMG_3504

I've also liberated the manual for download, in case anyone needs a copy.

Update:

It’s gone. I don’t remember selling it, but I can’t find it :-)

Update 2:

I found it again. Anyone need it? Yours for the cost of the postage.

SOLD: Tektronix "2440 Digital Storage Oscilloscope Operators" manual

In one of the piles of junk from a lab cleanout I found a Tektronix “2440 Digital Storage Oscilloscope Operators” manual, PN 070-6599-00, Product Group 37.

IMG 4527 (1).jpg

It’s in good condition.

IMG 4528 (1).jpg

It’s the December 1988 revision.

IMG 4529 (1).jpg

What makes it “good condition” instead of “excellent condition” is that the back cover has a few tears around the punched holes for the comb binding, and the cover has a little wear that has exposed the white paper under the blue color. The interior pages are in like-new condition.

I’m asking $20 plus media mail postage.

SOLD: Antique Homebrew Radio


IMG_0763

I'm parting out this old homebrew radio.

IMG_0753

It has four Pacific rheostats,

IMG_0755

two with porcelain bodies

IMG_0754

and two with Bakelite bodies.

IMG_0758

The second Bakelite rheostat.

IMG_0767

It has part of a plug-in spider-web coil with adjustable coupling.

IMG_0766

Another view of the adjustable coil socket, and a SPST toggle switch.

IMG_0752

There are three Dublier 0.5 mfd condensers, some fairly dirty

IMG_0765

and some fairly clean.

IMG_0756

There are two Capacigrad straight-line wavelength tuning capacitors 

IMG_0757

with brass plates. The second one doesn't have the manufacturer's name on the back plate, but it's clearly of the same pattern.

IMG_0759

I haven't checked the audio interstage transformer to see if the windings are intact. There are also four four-pin tube sockets, a grid-leak capacitor with grid-leak resistor clips,

IMG_0760

and several miscellaneous resistor clips.

IMG_0761

It has two sets of battery and antenna Fahnstock clip strips.

IMG_0762


IMG_0764

Finally, it has two telephone-style phone jacks.

The base and panel are available, too.

Sold to Norm at one of the NEARC shows.

SOLD: Broken Leeds & Northrup Galvanometer

Somewhere along the way I picked up a Leeds & Northrup bridge made for Western Electric. It's a KS-10376 Null Voltage Test Set. Unfortunately the galvanometer was dead. The coil is open. It's probably burnt out.

IMG_3328

The horseshoe shaped piece is the external magnet.

IMG_3329

The coil is inside the meter assembly. I haven't tried to open it up and look at it. It'd be a challenge to rewind the coil. 

IMG_3331

Here's how it looks all together.

Anyone want it? It's yours for the cost of the postage to get it to you.

Gone to someone who needed it for a L & N bridge as a display piece.

SOLD: Toshiba 6TP-385

IMG_0511

I'm selling this for a friend. It's a nice Toshiba 6 transistor portable AM radio from 1960.  It needs cleaning. Somewhat surprisingly, it does still work. It is somewhat intermittent, though. The circuit board is missing one of the mounting screws, and reception cuts in and out as the board moves around a little.

The tuning is interesting as it has a geared drive to the tuning capacitor. 

IMG_0518

The radio has an internal ferrite bar antenna, but it also includes a telescoping external whip antenna that screws into a socket on the top of the case. The cosmetics are fair; there are some scuff marks and scratches on the case. The case is  dirty and there is yellowing. The front metal grill is good.

IMG_0512

Here's the back. There are two cracks in the back of the case in the second and third louvers down from the top on the extreme left-hand side.

IMG_0513

You can see the cracks better in this photo, as well as the injection-molded badge.

IMG_0514

A view of the bottom.

IMG_0515

Top view.

IMG_0516

Left side.

IMG_0526

There is a hairline crack in the case on the left side, near the top. You can see it on the right-hand side of this photo. It extends around the corner and ends at the back, just where the corner radius ends. The crack is tight on this side, but you can catch your fingernail on it a little after it rounds the bend at the top of the radio.

IMG_0517

Right side.

IMG_0519

Interior view. The whip antenna is intact. It does have a slight bend in the top section, but it's not kinked and it telescopes easily.

IMG_0522

The battery compartment has a little discoloration at the bottom of the battery cardboard. This may indicate that there was some leakage at some point, but the PC board looks clean from the top. I didn't pull the circuit board to check the traces underneath.

IMG_0521

Label inside the back. Note crack in second and third louvers down from the top on the far right-hand side.

IMG_0502

The radio comes with a leather case that is in fair condition except that the strap has broken. The snaps for the strap are still attached to the case, so you might find a leather shop that could repair the strap.

IMG_0504

The back of the case. The pouch at the top is for stowing the external telescoping antenna.

IMG_0505


IMG_0507

Some of the stitching on the case is frayed.

IMG_0509

The leather is stiff, but not cracked.

Asking $40 plus shipping. Sold at one of the NEARC shows.

SOLD: Heathkit C-3 Condenser Checker


IMG_1138

A Heathkit C-3 with a healthy eye tube.

I acquired this C-3 capacitor checker along a with some other test equipment from the old Linear Electronics in Waltham, MA. They all were marked with "Dr. Ch. Allemand's" sticker and were set up for 230 VAC. I guess Dr. Allemand immigrated from Germany and brought along some gear from his lab. Anyway, this C-3 is unusual in that it doesn't have a dual-primary transformer. The manual includes a sheet on wiring a dual-primary export transformer, but the unit contains a single-primary 230 volt transformer.

IMG_1149

230 volt innards, but stock US-style 115 volt plug!

Surprisingly the unit has a stock US-style line cord and plug. 

IMG_1139

Interior top of chassis

IMG_1140

Interior of bottom of chassis

The unit is well-built, presumably by Dr. Allemand. The components appear to be stock. The capacitors need to be replaced; the paper caps are almost certainly leaky, and the eye tube has a flutter that I think is probably due to excessive hum due to bad electrolytic filter caps.

IMG_1141

Front panel.

The external cosmetics are fair.  There are some splatters of white latex paint. (Why does white paint alway spill near the stockpile of electronic goodies?) The front panel shows some mottling. I'd try some auto rubbing compound to try to revive the paint finish.

IMG_1145

Front view.

IMG_1144

Back view.

IMG_1146

Paint splatter. Might clean up with some Goof-Off.

IMG_1148

It still has its feet.

I also have the original manual with fold-out schematic and wiring diagram for this unit.

I'm half-tempted to replace the transformer with a US-version or mount a 120-to-240 volt transformer inside it, but this unit really belongs back in Europe or somewhere else with 230 volt power. The shipping cost would be horrendous, though. It weighs about 2 kilograms. What to do, what to do? 

Anyone want it for $40 plus my actual shipping cost?

I sold it to a fellow in Spain via the Antique Radio Forum Classified section.

No longer for sale: HP 5360A computing counter

IMG_3420.JPG

To do: sell this boatanchor to someone who wants to tinker with it. I've decided to restore the beast; it's one heck of a lot of TTL, apparently including some HP custom chips, but I need a good counter and this one's sitting here in my shop ...
