    Hi all, I bought an non-working Yarland FV34B III off raindance, once of this forum, and am finally getting round to doing something with it, so in order to get started I am trying to find a schematic to follow, all info much appreciated.
    Thanks
    Tony

    Hello mate, the Moth is fine, in fact very fine, I`m very pleased with it it works well into my valves and Lowthers. Although one of my 300b has gone pear shaped and I have no tunes at the moment hence my work on the Yarland, I`m even getting a ss amp to tide me over. Anyway the Yarland is the 34B version and uses EL34 valves not EL84 and is different inside, but thanks anyway. When I bought it off raindance he had started to modify it so it wasn`t in a working state, now I want to get it going and need to see what the standard configuration was. Mind you if I knew what I was doing it would help !!:D Still faint heart and all that, anyway what the worst that could happen ..........................................

    Hi Pete, I`m struggling to make progress with the amp without the schematic but the pics in the link may help, thanks. I will have another look over the w/e and see what I can do, I may pop some pics over for you to look at, maybe you see what needs to be done.
    Regards
    Tony

    I can't see any link to the pics of your amp ?

    but first up do you have a multimeter ?

    if so check the signal continuity.....

    then with a dumby load on the speaker outputs [a 8 ohm 5 watt res]

    check the heater voltages ..normally about 6.3vdc

    then the valve supplys ......

    if its in part mod form it could be a simple loose connection ......

    are both channels down ?

    if yes could be the psu
