Cap Job

[RiccardoSG]

I have a 70's Fender Silverface Amp ( Dual Showman Reverb master Vol) and I want to change the power supply filter cap and the bias filter cap.
I bought 2 Sprague 100uF-350V, 3 Sprague 20uF-500V to replace the power supply filter cap and a Sprague 100uF-100V to replace the bias filter cap.
Should I form/re-form the power supply filter cap and/or the bias filter cap before I use it?

No. Those are some high priced filter caps but they will do ok. If you ever get a chance, cut one of those Atoms open and take a look inside and see what you find.
