Home Tubes Asylum

Questions about tubes and gear that glows. FAQ

Ahah!! Now I get it!! It's the current peak of a low DCR secondary....

...that kills the tube diodes!!! I didn't understand that. I also now see why it's probably better in the overall picture to go with a center-tapped secondary and two diodes for full wave instead of a non-center-tapped secondary and a four diode bridge; otherwise the power goes through two diodes in series. It doesn't hurt the tx to have the power go back and forth between two halves of the secondary; it's just more wire to get to the same desired resistance.

I don't have a problem parraleling the power tubes; in terms of the whole cost of a really good amp (in this case seriously over the top guitar amp, but same deal) it's only an extra thirty or forty bucks including sockets. I'll save that winding my own chokes.

Cool. Thanks. The clarity I get from helpful people like you is just precious; now I know precisely how to proceed. Now that I finally have a digital camera I will get some pictures posted of Max's first guitar amp; it looks god-awful but sounds like heaven. :)
