Converting a Threshold S300 to SA/3?

[PKI]

That's ok just curious. Seen one locally. Thanks.

Mine sadly does not have the extra windings. Might as well look for a replacement transformer.

As the original PS caps are far from great sounding, the reduction in voltage also presents the opportunity to go for lower voltage/higher capacitance/better quality caps should you decide to make the change permanent. If the bridge cannot take it, might as well go for some better sounding rectification too.

Btw, replacing the NFB decoupling caps from the original polycarbonates to Musicaps worked out extremely well.

I replaced the original PS caps with a pair of 68000 uf at 75VDC, along with solen NFB de-coupling caps. Yes, it does help indeed.
