Marshall JTM60 Trim Pot Location

[Nooner]

Anybody know the location of the bias trim on this amp? Thanks.

It is RV101 somewhere inside. Look around, there are not going to be a lot of adjuster pots in there.

Thanks. I looked around and I don't see it and there is no RV101 on the schematic. Any ideas?

With the front facing you its on the board the valve sockets are on
bottom right a vertical mount trim pot.
On the JTM 60 Power schematic it is bottom left, directly under the grid
resistors to the power tubes
