Hi. these type of 50K pc mount pots are getting very hard to come by in a drop in replacement form, so give me a while longer to continue my search.
It may come down to piecing componets of two different pots together as I have done in the past.

In regards to getting nut off the pot and the board dismounted from the face of the amp there are two different ways to do it, and you are down to the last choise of how to get it off.

What you have to do at this point is use a dremel loaded with a cut off disc to cut thru opposite sides of the pots hold down nut, but the cut off disc must be reduced in diameter some by waring them down first on stone,brick concret or another section of metal
.
In this way it will be small enough to not cut up the cast contorl ring on the face plate of the amp, but yet be big enought to cut most of the way thru the nut and then let you just snap it off.

The job is not as bad as it sounds and the whole thing takes about 15 minutes and be sure to ware eye and nose protection.

The lamp/bulb number A GE 335.

Be very carefull when prying off the blue lamp cover or doing any work on these two switches as the plastic mounting section of them as got very brittle with age and snaps off easy.

When you load the blue lens/cover back in place be sure to hold/support the ass ned of the switch from inside the amp.

It helps at times to use a section of automotive or fish tank vacume tubing to remove and install the lamp.
