I have a mid-production unit, serial number 2325. These are unbelieavable radios and you should acquire one at any cost! They are worth every penny. When my new shop/shack/museum is completed this year, I hope to be able to replicate these efforts for any Collins fan at my cost. I put the dial drum in my lathe, turned off the old decal and put on a reproduction.ĭigital pictures of this radio cannot possibly do it justice! It has earned it's own dedicated table in my museum. The chassis is absolutly 100% mint and sparkles like the day it was made. To 'spruce up' the A4, I polished the tube shields, painting the inside of them black. Recently, I purchased a PD-1 (Product Detector) for the J3, and I have not used it yet. However, the only other tube radio I have that can play with the A4, is my Collins 51J3. I have a mint '67 EAC R390A with a CV-571A SSB converter (yet to be 'refreshed') so I can't rule this combo out. The result? Probably the best radio I have in my museum/collection. Some specs were right on, othere were WAYYYYYY out. 2.1KHz and 3.1 KHz filters I had acquired.

I did the mod to remove the B+ from the: 500Hz. I gathered all the information on the Sure enough, all (!) the bypass caps were NFG as were several of the micas. And this is from a ham of 45 years, (and a retired EE), who can't leave ANYTHING alone! During this time I acquired many new HF radios including an Icom 756Pro, a 706G (both bought by me, in Tokyo and carried on the plane back). I left the radio alone for about a year, because it worked so well, I just couldn't imagine it being any "better". part of 10 M was dead, but that was just a matter of tweaking the osc. Mort, I don't know how you do it.unbelievable.īack to the radio.It played perfect, out of the box. Several ham buddies simply cannot believe how good it looks. What is really amazing is that the paint is a perfect (and I speak as a car builder) and I mean perfect, match to old # 029. I defy anyone to tell it is not origional.

After having sticker shock at the 270 series Collins speakers, I ordered one (reproduction) from Mort Jones. I immediatly thought that this radio needed a companion speaker. This radio had the 4:1 knob and gears installed, which I feel is mandatory. The condition of the paint was near perfect. The radio arrived in the most elaborate packing I have ever experienced! Even the Xtal calibrator was removed and wrapped in styrofoam, as were the filters. I was told that my radio was "nice, but needed the usual recapping, etc", a 'working radio'. I purchased this radio sight unseen upon the recommendation of K8DR, from W4XO. My pride and joy, is a perfect example of the state of the art in 1955. Hi, let me preface this by stating I collect receivers. My IC-7610 and TS-890 will be LONG gone before my 75A-4. The only reason for the 'update' is that Electric Radio has a NEW book with every known fact/improvement ever found for this great old radio. Although only one of mine was 'leaky', they don't age well. In addition to the paper cap replacement, I suggest replacing the mica caps as well.
Yeah, mine is an 'oldie' but it has been upgraded.
