    The PPL08AC Project

    Hi Apheared thanks for the link to see the schematic but I can't see it, my stupid computer tries to convert things to m/sft word. Is there another way I can view it? What value is the vol pot? Do you ever have problems with instability on your layouts? and finally as the EL2001 has a large...

    A learning curve but need help

I have re built it now 5 times but it still suffers from instability and oscillates when the vol pot is advanced a little. I have been very careful with layout and tried varoius ways of...

He has been a recluse for many years but his music lives on. Peter Green Songbook, Seagull 111101-SG, a great double CD of his work...

    I give up!!! how do you solder??!

    The best iron to use is a variable tempreture soldering iron. You get to know at what temp it is best to use it at, not too hot, just so it melts the solder and a bit more.

    SEAL
