Hi!
Does anybody know the tube layout for 2:90? I can't believe it's not in the manual...
 
does anybody know wich tubes are for chanel A? I know there is a label in the back of the poweramp, but i don´t trust it....fuses layout in mine is wrong, weird but true!
 
I have a schematic for the 2:90 that shows that the tubes are grouped as shown on the back of the amp, that is in a quadrilateral group of four instead of the top row of four and the bottom row of four. To figure out which side is A just take out one group of four and see if the A channel still works.
