Bias and Balance pots

I have a Scott 272 and I would like to replace the bias and balance pots
with more reliable pots. Does anybody here have any suggestion on what kind
of pots I need and what wattage I should be looking for. I looked at
mouser.com and I know the ohm rating for the pots but it's like looking for
a needle in a haystack especially when you don't know what type you need.

I can't find online schematics for the 272.

Here is the best archive of scott schematics I can find:

My faint recollection is that the LK72 was very similar to the 272, and this
page has a schematic for the LK72.

If you have the space for them, the reasonable-overkill replacement pot of
choice would be a RV4NAY-type 2 watt potentiometer of the appropriate
resistance value and with a linear taper, such as the ones listed here:

Thanks everyone,
Eddie
