Simple cheap 2A3 stereo amp

Hi,

If you put diodes in series it is good practice to use equalising Rs across them.

An added side effect is that the ripple is smoothed better than a single diode does.

When in // the current carrying capability is doubled and you can actually put as many in // as you like provided they're all of the same type.

Thanks Frank. Found it by going to the main directory of Tubes.

Duh on me! ;-)

You can get more voltage rating by putting a pair of 1N4007's in series - each sees 'half' the potential difference (this is what PSUD II means by 2x1N4007 if I'm not mistaken). If you need more current carrying, you can put a pair in parallel instead (and I suppose you could use 4 of 'em with 2 parallelled series pairs in each leg of the rectifier, though I've not tried that).



All the best,

I thought that's what they were eluding to but I wasn't sure. So, it follows the rule, series circuit/voltage adds, current stays same: parallel circuit/current adds, voltage stays same.

Thanks for the tips and the hybrid idea.

Hi,

will anybody accept that use 417a/5842 push 2a3Se.

Also a good choice.

thanks''

Sure, that would work nicely.

hi fdegrove,

so cheaper choice, use 6C45 to relief we437a to push 2a3/45.
any opinion.

thanks
