    Hi Chris,
    I have an EC10 that lay unused for some time and I would like to have it going again. The local oscillator refuses to work on the lower bands 4 and 5. I have checked all the voltages as per the data and they seem OK. I then checked the switch contacts and they were OK. Then checked for resonance with a GDO and the coils look fine. Any help would be greatly appreciated.
    Regards Dave

    • Dave there are several articles on restoring EC10s in the Technical section of the website. Failing that I suggest you join the Eddystone User Group Yahoo Forum which has members who can possibly help you with technical information on the EC10

  2. Have three Eddystones, an 830/4, an 840C and a 770R. Two were purchased on eBay, as separate items, and the 830 from a local junk store. I gather the 830 came off a scrapped Canadian Coastguard icebreaker.
    Part of the problem seems to be that the stringing has come off the various dial pulleys of all three receivers. Is this common? Any advice or comment appreciated.

  3. I have a small number of vintage “Lighthouse” Eddystone newsletters and magazines that I would be willing to share with an Eddystone User Group member here in the USA. They were given to me, are extremely interesting and I think they should be passed along for others to enjoy.

    Hi Chris,
    I have just obtained a 770r MK2 and I was wondering if you know what type of plug is required for the speaker connection, I am reluctant to change it as the radio is pretty much original.

    Hi Chris,

    I have an EB35 (serial 1579) the FM band stopped working in it’s early days but was not missed as the radio came to sea with me and also to Nigeria shore based.
    In the 90’s a work colleague who was a radio ham; offered to to try and sort the problem without success.
    Time has moved on and I wondered if there was any possibility of replacing the module (6940) or having another try at fixing it. I intend to study Gerry O’Hara’s article to glean some info. but my radio knowledge is limited to assembling a couple of kit receivers in the early 60’s.
    Any pointers would be much appreciated.

    Kind regards,

    Michael Donnellan

    I have a 670A in pretty good condition…. but since a few years it remained silent. I noticed a couple of soldering have loosened…around the resistor. Does anyone have photographs of this part, so I can fix it? I am not exactly an electronics expert, but know what to do and not to do anyway.

    Thanks a lot.
