NOS Vintage Sylvania 1N48 glass body Point Contact Diodes
These are new old stock Sylvania glass body 1N48 Germanium point contact diodes, the early style with the metal caps and clear large glass body. These have been tested and are excellent crystal radio detectors, subjectively as good as any 1N34 diodes I have. They have the full length leads as shown. $5 each and free shipping within the US
Package of 7 Germaniun Point Contact Crystal Radio Detector Diodes
Assortment of seven diodes. One vintage Sylvania 1N48 diode, two Russian D9B detector diodes, two US made NOS military diodes, and two modern 1N34A diodes.
All work great for crystal radio detectors. $6 and free shipping within the US.
Package of 12 Diodes
A dozen new old stock military germanium point contact detector diodes, (sorry the photo only shows 10 but offer is for 12) behave like 1N34A but they are unmarked so I don't know the exact specs, but tested and work equivalent to any 1N34A diode I have. $5 and free shipping within the US on this offer.
Special offer 100 of these diodes for $15 postpaid within US.

Wen Model 100 Soldering Iron
This is the soldering iron only, Wen Model 100, quick heating vintage soldering iron. As above but no box or other extras. $19
Have several other Wen soldering irons, some in the original cases,
will post soon, inquire if interested.
Wen 199K soldering iron, has new tip installed and works great with fast tip heat up. The metal box is rought but the gun is in nice shape. $26HOLD
Have several more in various conditions.
Sylvania 1N38 Vintage Ceramic diodes
Earliest Sylvania model of the ceramic body germanium diodes. Have 2 of these, great crystal radio diodes, unused. $7.50 each
Kemtron 1N40 Diode
Vintage Kemtron 1N40 diode, great crystal radio diode, tested. $3
Kemtron K345 diode, also tested and works great on crystal radio $2
Kentron Gold Diode
This is a gold clad Kemtron diode, exceptional crystal radio sensitivity $8
Sylvania 1N34 glass body diode
I have a few old Sylvania 1N34 Glass body point contact germanium diodes, most are used with the leads as shown in the photos, but have been tested and show excellent crystal radio reception and sensitivity. There are a couple different body styles, the smaller one on the left and the larger one on the right. I have a few of each. $4 each.
NOTE: Be careful if you solder the leads on germanium diodes as they
are heat sensitive. Wrap the body with a small piece of wet paper towel
and minimize the amount of heat used and quench the joint as soon as it
Military Signal Tracer
This is a compact signal tracer milspec in working condition. Comes with the AC power cord, but no input cable or other accessories. I tested it on a crystal radio circuit with headphones and it is in working condition. It uses a 12AX7 tube which is good. $15SOLD
TV-7D/U Red Plate and Grid cap lead
This is an OEM grid and plate cap wire lead for TV-7D/U and similar tube testers. $7.75 includes FREE shipping within the US.
This is a little relay rated with solenoid of 26.5 V at 675 ohms resistance. It closes quite nicely using 18 volts from two 9 v trasnistor batteries on the solenoid. It is milspec new old stock. $2
7 Amp choke
This is a high current 7 amp 1.1 mH choke, used, tested and shows good continuity. $3sold
High Voltage Oil Filled Capacitors
This is a lot of six oil filled high voltage capacitors, only one has been used, the other 5 have never been soldered. The GE one on the bottom left is 0.1 uf at 1500 VDC, and the one on the bottom right is three sections of 0.1 uf at 600 VDC. All 6 caps for $10
25K Ohms Dual Potentiometer with the concentric
audio taper 2 Watt
These are no longer made in this resistance range. These are dual potentiometers, each section can be adjusted independently using the dual concentric shafts. Outside shaft is 1/4 inch and inside shaft is 1/8 inch diameter. Each section is 25K ohms audio taper and the plate is high quality ceramic. Comes with washer and collar nut for the panel mounting. $3 each, or $29 for a dozen
