My old rebuilt superlead built from an old JTM100 master volume PA onto a chassis I obtained a long time ago. Took me a couple of months to rebuild but sounds excellent and nice and loud. Laydown mains transformer with dual windings! I have kept the old RS capacitors but recapped as did not want to risk damaging the mains transformer. Now just got to get a suitable cabinet built!
Note the early JTM100 Dual Rectifier Power Board.
Although I fitted with RS caps decided to recap with modern caps Did not want to risk damaging the rare laydown dual winding mains transformer
The early JTM100 master volume PA that I rebuilt the amp from Took ages and had to find suitable old stock wires where some would not reach
Note the White and Gold logo which I shall use when I get a suitable cabinet built
