Have been looking for a few replacement felt washers, does anyone know of a source besides Audio Classics? They want $2.05 per washer which I feel is a bit excessive ;-)
This is from the MA6200 service manual. You probably don't need the 5/8" size. They are for the five tone controls. The 3/4" are used on many, many models.
Geez...... folks..... . think out of the box ! Just purchase typical Musical Horn Felt Pads. The felt pads are mostly for light blockers and in the case of an inner and outer knob they act like a spacer. $7.19 for a pack of 10. There are probably better deals and sizes but here is one: https://www.ebay.com/itm/231428515206?epid=1800042928&hash=item35e236e586:g:PHsAAOSwQiRUluYS
