Hi
As the volume potentiometers has a substantial influence on the sound I wonder if it is a good idea to replace these old 20kohm potentiometers with new ones on an Altec 9440A power amp?

Any recommendations for replacement. The same type, Alphs (may not fit) or stepped attenuator ?

Anyone done it ? Any idea for good replacement ?

Not any good idea ! The originals are good enough !

Any input appreciated
