Replacement for 200 Ohm variable resistor?

[maurycy]

I am trying to find a suitable replacement for 200 Ohm variable resistor. The resistor is in Sansui AU-101 amplifier. Here is the information from the service manual:

200 Ohm (B)
Part # 1032021

Here is the schematic:

Here is the picture of the actual trim pot:

Can I use any 200 Ohm trim pot as a replacement or the (B) means something? This VR is used to adjust bias in the amplifier. Sorry if this is a silly question.

Thanks.

the "B" designation means a linear variable resistor rather than a log (volume) type.
anything that will fit should do

Thanks for replying.

Any idea what wattage/voltage should I go for?

From the photo its a carbon preset say @ 30mw / 100volt., IE as cheap as sansui could find

any of cemet / carbon presets will do, cemet would be @ 200mw to 500mw at that size.

something like 652-3309P-2-201 at Mouser would do, may need to bend its pins a bit. Its a bit of overkill compared to the original.

Thanks for replies. Will get the trimmer from Mouser next time I have to order something from them.
