Could anyone who has any experience with replacing the bias trimpots on the Nak PA-7 please let me know what multi-turn trimpot is best to use.
Essentially need to know the resistance rating..but any further info would help.
The trimpots on my PA-7 are wonky to say the least and I can't get a steady bias setting at 40mV.
Thanks

vr 101/201 are dc offset adjustments.
and i do believe their are several 'revisions' of this amp.
manual i have covers "pa7/pa7e"
No mention of 'power ratings' for the trimmers, so id suspect whatever 'bournes' multi turn floats ya boat
Bourns are what i've fitted into my Pass Labs x150.
sorry i can't be of more help.

Service Manual
vr 101 - 4.7k
vr 102 - 150 ohm
Can I exchange VR101 to 5kohm trimpot and VR102 to 200ohm? I can't get 150 and 4,7kohm.
