Still worth some new caps you can get 4700 uF in where the 2000 uF's
used to go..

Bet PW would have used them had they been around



** Maybe not.

If you are using Quad ESL57s, the output cap can interact with the transformer and create series resonance - hence a very low impedance at a sub sonic frequency. Bad news when using a TT.

One reason why the 303 has a HPF built in.
