Over at www.18watt.com, there are a few designs of the old Marshall 18watters they put out in the 1960's. These things sound pretty freakishly amazing, as does mine.
I built the "Lite IIb" version with tube rectification and a VVR (variable voltage regulation) unit that I originally bought for my TC15 (see post below) but I never installed it in that amp.
This amp sounds absolutely fantastic and it really nails that early Marshall crunch sound. Does that "classic rock" sound REALLY well.
Uses a pair of EL84 output tubes and Classic Tone power and output transformers.
More to come......
