Collins 75A 4 Receiver After Refurbishing 

Yes, its a real pleasure to use!

Thanks Richard. I was thinking it must be about time I found another interesting Eddystone set to work on - problem is that friends I have that own them are more than capable of working on them themselves, and I don't want to start buying and collecting boatanchors again, having divested of most of my collection as part of my 'downsizing' efforts. Hmmmm - I need to think of a new strategy....

Glad you like it. The matching KWS-1 transmitter and power supply are waiting to be refurbished later in the summer/Fall. These are also in excellent condition.

Hi Mike. The owner of this set told me he bought the 6KHz filter as it was missing also - its a 'Longwave Products' part and works well

Have fun Rod - these sets are quite straightforward to align.

Indeed - the owner is a very lucky man (and who also owns the matching KWM-1 and power supply - that I have yet to refurbish)

In summary, replacing all paper and electrolytic capacitors, checking resistors/replacing four out of tolerance resistors, testing tube/replacing weak/failed tubes, cleaning switch contacts and controls and realignment. If you are on Facebook, you can read my blog that details all the work done: facebook.com/gerrysvintageradio/ . I am also preparing an article that will be posted to the SPARC Radio Museum website.

@@RadioRestoration That's fantastic, well done Sir.

@@union310 I forgot to add that I also changed out several silver mica capacitors that are known to give problems, plus one in the 11M 1st local oscillator circuit that had an intermittent

@@RadioRestoration I am a model engineer in my spare time, I build all sorts of stuff from locos to traction engines and clocks as well as machines to that. I have always had an interest in Ham radio and have recently passed my foundation level. I made myself a Morse key last weekend, a little different in places but it works well as well as looking nice in Oak and brass. The aspirations are to pass they next two levels and build a transceiver.

@@union310 All the best with the ham exams. I was G8GUH in the UK (licensed in 1972!), VP8BDE in the Falklland Is (mid-1980's)., and now VE7GUH in Canada

At least its application to a high-end ham bands only receiver!
