WOW, check this out! This seems to be from the mid to late 1950′s. I believe it was manufactured by CONRAC?? This was brought up slowly on a variac. It powered up just fine. Some residual DC was noted on the output when unloaded. When loaded with a 10K resistor, DC dropped. I was able to tun in to a FM radio station and it pulled in strong reception even with just a 6 piece of wire attached as an antenna! The EYE tube is very weak, but it is working. It is very dim but you could see it move as you tuned in and out of a station. Volume and tone controls worked. I did not try any other inputs. I did not want to leave it on for long. An item this old will need to have the capacitors replaced for continued safe operation and should only be performed by a knowledgeable tech that is familiar with the high voltages involved with Tube equipment. As this is over 60 years old. It will be packed VERY carefully. I was not able to figure out a proper value on this item. Send me a message and lets talk about it.
