Old Radio Parts:

Light Bulb Batch

There are at least a couple hundred light bulbs here, including 43, 44, 46, 47, 48, 14 bulbs for antique radios, GE 67, NE-48, NE-4, NE-51, 84, GE-82, PR-2 flashlight bulbs, some halogen bulbs, some 120V bulbs. Whole batch for $9 plus shipping.

National Variable Capacitors

Vintage high quality National brand variable capacitors in their original colorful boxes, unused new old stock. I have several that are 20 pf and several 25 pf. $16 each

National 25 pf differential capacitors

This is a pair of National 25 pf differential variable capacitors. An uncommon type that varies the capacitance between the center rotor and 2 side stators, kind of like a potentiometer with capacitance instead of resistance. Can also be wired with just the center and one side to use as a standard variable capacitor. Comes with the original box and a bag of mounting hardware. $25HOLD JD for the pair.

Batch #3

Batch of tubes and stuff. Includes a 7 pin mini tube socket, a 6 volt vibrator, IF coil, GE lamp,  relay contact set, and tubes 6BA6, 12CR6, VU111, 6802, 6Q5, 7QL7, 6AC5, and some unidentified tubes. I was able to test 3 tubes, the 6BA6 tests good, the 6AC5 tests good, and the 12CR6 is weak. The GE lamp has good filament continuity. All for $8

Geiger E-Z Tester Tube Tester

This little Geiger tube tester comes with the original instruction sheet and the original company box. I have not plugged it in to test it. $19

Capacitor with nice dial

This old 1920's era capacitor has a nice 3" dial with a concentric vernier tuning knob, though it is not attached to anything now. Main dial tunes the single plate on the rotor. $

  Zenith Wavemagnet and cable

This is a Zenith Radio Wavemagnet and the cable from an old Zenith portable radio, model unknown. $6

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.

Also have some NOS Sylvania 1N480 diodes at $2 each

Package of 7 Germanium 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.

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.
Special offer 100 of these diodes for $15.
