Opened up my VTA SP/PH 12 to replace the stock scratchy dual mono gain attenuators that have been bugging me for a while. Don't have a project going at the moment and the slippery slope of OCD-guy mission creep has set in. Now I'm pulling boards out of chassis, rewiring portions, replacing resistors and have new coupling caps on order for the SP-12.
My question - has anyone tried upgrading the Panasonic(?) metalized polyester output caps on PH-12? I won't throw boutique parts in this position, but maybe some sort of basic polypro can be shoe horned in there. Thanks for any input.
