 HEATHKIT SIGNAL TRACER T-2 $40  
HEATHKIT SIGNAL TRACER T-2 PRICE LOWERED $40 PLUS SHIPPING COST This vintage HEATHKIT Signal Tracer Model T-2 #67 (my number) is in excellent cosmetic condition. I replaced the 2 power supply filter capacitors and the 6 paper capacitors with modern capacitors. I also replaced the A/C power cord, cleaned the switches and potentiometers, and the tubes tested good. I could hear static the volume controlled by the GAIN pot when the probe was touched. The probe is not original but is electrically the same. Not all functions were tested. Due to the age of this item, it is being sold AS IS!! Shipping will be within continental USA only, no international shipping.

 HOME BREW VARIAC A/C POWER SUPPLY  
HOMEBREW A/C POWER SUPPLY
This home made A/C power supply PRICE LOWERED AGAIN ($40 PLUS SHIPPING) is in good functional and cosmetic condition. I purchased this item at a local sale. It has a variable autotransformer VARIAC at 120 Volt A/C input 0 to 134 Volts 2.5 Amps output. I added the output fuse holder, voltmeter, and input power indicator lamp. The indicator lamp illuminates when the unit is connected to 115 volt A/C power source and the power switch is in the ON position. The A/C output is fused at 2.5 amps. This is a great tester for use in testing and repairing vintage electronic devices, as it can be used to bring the voltage up slowly while monitoring the current and reform older electrolytic filter capacitors. Shipping will be within continental USA only, no international shipping.

 SHARMAN AV-1000   
NEW 400W HF/UHF SWR/Power meter
Frequency range:
1.8 -160MHz
430-450MHz
800-930MHz
1240-1300MHz
Power: 5W, 20W, 200W, 400W
SO239 for 1.8-160MHz
N-type for 430-1300MHz
Bought this to use with my IC706MKIIG.
As soon as I unboxed it to try it, I noticed the problem. The 'N' connectors are used for UHF measurements. The meter's SO-239 connectors accommodate 160m thru 2m. The 706 has separate SO-239s for HF and VHF/UHF. I cannot connect my 2m output to the meter's SO-239 when my HF antenna is already connected!! Nowhere does/do the dealer(s) tell you that.
I like the meter. Seems sturdy, it's good looking, and would be easy to use.
