    I lost my EC Mk 2 in the Black Saturday bushfires back in 2009, I had been a SW Radio DX’er in my teenage years, so it had been a dream of mine to replace it.
    Managed to find one on ebay, bought it and of course when the seller said he didn’t have the ability to test it he meant it didn’t work!
    Got the manuals from your site (thankyou VERY much) and did the voltage checks. ANd mine are considerably different – but my basic electronics is just that, very basic.
    SO I was wondering what these voltages actually mean, or what do I do next?

    TR1 C 6.08 B 0.562 E 0.288
    TR2 C 6.11 B 1.038 E 0.993
    TR3 C 5.96 B 1.557 E 1.324
    TR4 C 1.976 B 6.07 E 0.322
    TR5 C 0.338 B 0.384 E 0.120
    TR6 C 5.55 B 0.857 E 0.615
    TR7 C 4.41 B 0.996 E 0.883
    TR8 C 9.17 B 1.683 E 1.558
    TR9 C 9.42 B 0.152 E 0.021
    TR10 C 9.42 B 0.152 E 0.021

    Voltage at yellow and red at AF Gain on/off 9.40

    Any ideas of where to go?

    • common problem with these sets is after so many years the OC170/171 transistors suffer from what people call whiskering where the ground lead on some of the transistors short out inside the device. Suggest you join the Eddystone User Group Yahoo Forum where you will find lots of people willing to help you sort this one out. Regards

    Hi Chris

    Here’s an item that may be of interest to readers. Hard to figure how this person thinks they can get this much, even for one of the rare Eddy models, but here it is:
