Collins 75A-4 On The Air!

A 75A-4 fell into my lap many years ago. It’s been sitting in the basement waiting for some tender loving care to bring it back to life. I brought it up last week and was delighted that every feature works! All 22 tubes seem to be fine, and without my touching any of the alignment, the set brings in signals just fine. Here’s a video showing both CW and SSB signals on the 20-meter band.

This 1955-era radio was then considered “top of the line” and is still a fine ham-band-only receiver. I brought it up slowly, gradually increasing the voltage, and was delighted to find that after at least 20 years dormant, it works fine! I’m sure a little more tuning will really make it jump.
