I have a custom "conversion" amp with a pair of el84's,2-12ax7's and an ez81/6ca4 rectifier.
It has a master volume and gain control in the preamp for overdriven tones at less than full volume.
Can the rectifier impart some compression with the master set low and the preamp set near full?
FWIIW the plate resistor's on gain stage 1 and 2 the values are 100k and the cathodes 2.7k and 2.2k respectively(not sure if those high values could factor in,5e3 has 100k plate but 820 on the cathodes). I checked the voltages,swapped all tubes but still it compresses allot with the pregain at/past %75.
It isn't terrible but it's a bit more than I would like.
