I am looking for a home for this COLLINS 75-A2 radio sn 1168. Yes, it needs some tender loving care meaning it needs work.
I’m open to suggestions on how to proceed. How can I find out who has a burn to restore this piece of history?
There is more background on the radio here – The original user manual is inside the case, however, it’s in rough shape. Readable though.
I’m open to ideas and reasonable offers and trades frr the radio. Let me know your thoughts. I am a fairly new Ham (~12 months). I’m more interested in QRP and SOTA type operations. I have an Elecraft Kx2 that I’m still getting my head around. Love this little guy.
Truthfully I could easily be swayed to trade the Collins with someone for occasional and kind mentoring or Elmer type help. I place a lot of value on learning. I am just getting going with CW work so that’s another area where a ‘buddy’ approach would be of value to me to ‘learn the ropes’. Or on the digital side, someone to help with DMR related questions. Or a simple cash transaction is fine. You tell me what works for you.
I’m available via email or phone and I have an IRLP Echolink hotspot in the shack so provided we set up a reasonable time to talk we can have a conversation in that manner. I live in Austin Texas and I’m in QRZ.
Here is some history on the radio:
Introduction Date / Price: 1950 / $440 Tube List: 0A2 (1), 5Y3GT (1), 6AL5 (3), 6AQ5 (1), 6BA6 (6), 6BA7 (2), 6CB6 (1), 12AT7 (1), 12AX7 (1).
The Collins 75A-2 receiver is dual conversion and covers the 160 thru 10-meter amateur bands. Selectivity choices include five positions for the crystal filter (approximately 5 kc to 200 cps bandwidth) and that of the 455 kc IF transformers for AM operation. The crystal phasing circuit provides a tunable notch rejection for phasing out interference heterodynes. Operating modes for the receiver include AM, CW, MCW. Accurate tuning is accomplished through the use of a slide rule drum dial calibrated in .1 Mc and a vernier dial calibrated in 1
Operating modes for the receiver include AM, CW, MCW. Accurate tuning is accomplished through the use of a slide rule drum dial calibrated in .1 Mc and a vernier dial calibrated in 1 kc increments (2 kc increments on the 10 and 11 meter bands). Separate noise limiters are used for AM and CW operation. Front panel controls
