I'm in the process of gathering parts for the PP 6CB5A amp which I've mentioned on here before. I picked up this transformer, mainly because it has high current 6.3v windings - the four 6CB5As alone will draw 10A!
I'm thinking of using a voltage doubler on the 176v secondary to provide the B+. The transformer doesn't have a center tap. I've used similar transformers with hybrid rectification in the past without problem but can a doubler work with this transformer? Also, I'd like to bring up the B+ slower than SS diodes would. Has anyone here used a pair of 6AX4GTB damper diodes (or similar) in such a doubler circuit? I have a bunch of them and have heard good things about them in normal rectifier circuits.
