Tube power board: Designed for 2 toroidal PCB mount xfrmers. The first in parallel to step down 120 V AC to a low filament voltage (12 V AC) This lower voltage is rectified and then has 2 adjustable LM317 regulated voltage outputs (designed for 9 & 12.5 V.) 4 jumper configured auxillary outputs. Switchable HV supply is provided through 2nd xfrmer in series (~280 V depending upon load and xformer power)
Compressor/OD board: Uses 2 12A(X/Y/U)7 tubes, with off board switchable compression and overdrive stages. Compression stage implements a variable-µ gain through the 2 LDRs (either LED or Lamp) which can be jumper configured to adjust the input bias (load-point) or the plate voltage to the compression stage. Internally adjustable Bandaxall tone stage as well.
External pot adjusted OD & compression levels as well as output level for each stage.
