These are the Heyboer/Metro Drake replica trannies, but I decided to wire it as a '68-style instead of '67-style, using NOS Mustards, Lemcos and a yellow "chicklet" on V1. I put a 27K NFB resistor which will feed into a 100K pot.
I am filtering as follows:
two 16uF on the preamp board,
two 33uF caps in series for 16.5uF total on the screens,
two 100uF Royal '67 caps in series for 50uF total on the mains,
one dual 32uF filter can for the PI (not sure whether to wire it series for 16uF, or parallel for 64uF)
Which is the most common value for filtering on the PI, 16uF or 64uF, or should I just use one side of the can for 32uF on the PI? Thanks in advance- co

Re: 12,000 Style Metro Build Question
32/64 works fine, the originals often had dual 40uf caps
