    Default Lowther L18 amplifier schematic

    Hi to all of you,

    Now this might be a difficult one, as there seems to be very little information floating on the web about the Lowther valve amplifiers. Does anyone have a schematic for the Lowther L18 valve amplifier? For which the valve compliment would be :

    2 - ECC82 (possibly configured à la williamson) followed by a pair of EL506 in fixed bias PP.

    Thank you in advance.

    Sorry Henri,

    Can't help you there. I have the schematic for the LL26 (using EL34 output valves in push-pull), but know very little of the L18. Is it a monoblock? Will try to do some research for you.

    Thank you Barry,

    ...It is a monoblock, it was made from 1957 to 1975, acording to the Lowther page. It would use diodes for rectification...


    Thank you again
