I replaced alot of damaged resistors and amplifier is powering on but i am a bit confused about why i am not getting proper current through the 2sk129a pair.
i have about 1.3ma on each side which gives a total of 2.6 and to my understanding from schematics it should be 2*2ma=4ma.
Q103,Q105 and Q107 replaced.
I was thinking of adjusting the value of R105 to get more current but i have not tried yet.
32.8v on schematic is about 38v.
I am mainly concerned because vgs is about -0.45v on the jfets and i think it should be closer to -0.35v to be on pair with operating range.
