I get higher voltages than that with the solid state rectifier. The higher voltage should actually give you more head-room (cleaner). The NOS rectifier tubes should measure about 35-45 volts lower and give a “browner” tone. The Two Stroke breaks up (by design), if you are looking for a clean, chimey tone, the Two Stroke wont get it.
TAN member Mitch was having a intermittent crackling/hissing issue that sounded like a tube, even with different tubes. It turned out to be the V2 socket, pin 8 sleeve needed to be tensioned a hair and the problem was solved. Maybe there is a batch of marginal tube sockets going around.
