    One helluva receiver. My cousin Norman (W1HOL - SK) had this with all the filters. Used to love listening to it as well as
    tuning around the 20-meter band. Still such a sought-after radio. That will never change. Nice presentation - Rich, W2FKN

      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

    Well done as usual Gerry. She’s a real beauty. Not an Eddystone of course… but still nice. Lol

      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....

    I have my Dad's 75A-4 from the 1950's.
    I have recapped. Need to finalize the procedures.

      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.

    Can I ask what the refurbishment involved please .

      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.

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.
