I recently acquired a Dynaco PAS-3 and am going through the process of restoring it along with a few modifications to improve the sound while staying true to the intent of the design. I am trying to bypass the tone controls and found a great thread on this forum about how to do it on a PAS-3x. Is there any reason that the same modifications wouldn't work on the 3? I know the pots are different, I don't have a 3x to compare to see if the boards are.

How about using it for a while before changing ? Then you could actually compare the
results.
And what are your goal with the proposed changes ? What do you need that a stock PAS
cannot deliver ?

Can you send a link to the article you found? I’d prefer to read it before commenting. The 3x is already bypassed when the controls are centered.
