NOTE: Sorry, no longer
accepting Paypal for domestic transaction. Check or MO by mail.
May have exceptions for
overseas transactions. My state, Virginia, and now the federal
government, have decided to require reporting of Paypal receipts
to the IRS, resulting in the receipts being subject to federal and
state tax. There used to be a $20,000 allowance to allow for
hobby sellers to operate without taxing up to that amount. Now all
Paypal receipts are taxed as income so I lose about 40% to taxes
and can't afford that. I don't operate this site to make money,
and most of what I sell is about a break even for what I have
invested, but can't afford to lose money on it. Sorry for the
inconvenience, but we have our greedy government and state
legislature to thank.
Nice working Military I-177-B Vacuum Tube Tester
Nice working US Army Signal Corps I-177-B vacuum tube tester in
very good cosmetic and working condition. Shown above pushing the
Line Test button. Original test data book and copy of instruction
manual plus several update bulletins included. I have tested many
tubes on it including amplifier and rectifier tubes and get
reliable results that compare well with my other tube tester. I
recently had my TV-7D/U repaired and calibrated so no longer need
this one. It will test older tubes all the way back to an 01A, and
recent tubes up to the 7 pin mini tubes, but does not have a 9 pin
socket. There is an adapter that will allow testing of the 9 pin
tubes if you need one and can find one. Price is $195 for a good
working tube tester. It will test 4,5,6,7 pin tubes plus octal,
loctal, and some 7 pin mini. If there are specific tubes you want
to know about I can verify if there is test data for your tubes.
Two Circuit TRF Coil and Condenser
Coil and Condenser tuning units from 1920's TRF radios. They tune
the AM broadcast band. Each has a tuned tank circuit and a tickler
coil that could be used as an antenna coil or as a regen tickler
coil so you could easily build a one tube regenerative radio
around one. I have 3 of the black ones on the left and 2 of the
ones on the right. $24 each
