have made the "aleph 3 J" feedbach change 10K /1K 220uf to 220K / 22K direct to ground .
it sound louder as this so i presume the feedbach have changed a bit
You are probably getting a slightly higher input voltage with the higher input impedance...
try both,keep what you like
i prefer 68K but more heat on the heatsink: i'v got 0,56V on the 0.47source resistor !
for the AC gain i put the trimmer to 50% of the ouptut but cant honestly tell the difference between 40 /50 or 60 %
Sissy amp
you want a real sissy, ALEPH JM !
yesterday i was so afraid with the heatsink temp ( can fry an egg) that i remove one stage of CCS and Power transistor.
and also the current and AC gain resistors and running it as pure CCS
and the sound is a fantasticmellowbuttered ..
the only problem with this PaPa amp is to choose one variant as all sounds marvellous in their ways.

ok then - heatsink up to 55C
good now ?
for today !
