This Collins 75A-4 Vintage HF receiver, is in Very good to Excellent Condition! The serial number is # 3668.This consignment Item is part of a silent key Estate. It is being sold for his family, as is and as described. All Sales are final. This Collins 75A-4 Receiver is in very nice cosmetic Condition. It has the optional; 4:1 reduction drive tuning control, and comes with the 3.1 SSB Filter.(I do have the other optional filters available on my web site.. The front face and cabinet have no bad marks or scratches, just a few rub marks which are not bad. I recently tested this receiver on the air and it has excellent receive sensitivity on all bands except for 20 & 15 Meters which appear not to be working. There is also a 60 Cycle hum in the audio. lt has the original electrolytic capacitors, so it will need at least some of the the electrolytic capacitors replaced. I do sell capacitor replacement kits and will sell one for my cost to the buyer of this receiver. This is indeed a nice 75A-4 Receiver! I am selling this Vintage Collins Receiver as is, as described.Also included is a commercial Reproduction of the manual with all of the service and alignment information. As with most vintage gear, it may benefit with an alignment but seems to work fine as it is with the exception of 20 & 15 meters.
