  • Bugera Alchemist Schematic.

    Can anyone please supply a schematic?
    I have a Bogner Alchemist tube amp head that a customer brought in.
    The channel switching is acting up. Switches by itself, push Delay Switch & the Reverb comes on.
    I tracked down the problem to a bad 6L6 output tube. (B+ to heater?)
    The switching works with the supplied footswitch, but the front panel will not switch from Dirty to Clean.
    That is with the footswitch disconnected.
    I found a burnt trace on the front board,(-3V) but I am missing a positive voltage to the front panel channel
    switch.
