Collins Radio 75S-1 receiver w/ 500Hz filter and RTTY high-tone BFO:
$500.00

Well known Collins Radio 75S-1 HF receiver, wing insignia, with finger-hole main tuning knob, genuine 500Hz CW filter and RTTY high-tone BFO. Works all right with two 28MHz extra xtals. You may see famous IERC heat conducting/radiating tube shield on awesome hot or short life 6BF5 audio output tube. Been used with external/separate/remote DC power supply (140V and 6.3V) to avoid power line frequency modulation on the 70K-2 PTO, mechanical filters, and ferrite cores in the circuit by the leakage magnetic flux from the power transformer. The PS is quite heavy so reluctant to ship overseas, and modified 11P socket for this PS. Please provide the power cord at your end. Replaced the meter-zeroing variable resistor to multi-turn w.w. potentiometer to stabilize the zero-point.
The cosmetic condition is very poor, lot of peelings, scratches and stains.
The shipping cost, packed into a carton, by the EMS included tracking service, would be $145.00 to North/Central America, Oceania or Middle/Near East. To Europe, would be $166.00. Otherwise, please contact with the seller.
Thanks for your looking.
