22.1

22 IS CLOSE ENOUGH.

How do you get 22.1? I'm missing something with these five band resistors I think.

Ok, all parts ordered. Thanks for the help, I will be back shortly for a final check before fireup.

Ah OK. I understand now.
Final issue. Previously I removed the diodes. Should I replace them and which way round do they go, and are there better replacements out there now?

Aha, I found you previously suggested these for the rect:
'The FETs and rectifiers can be purchased from Digi-key or mouser (among others). I'd use the IRF3205 for the FETs. Order the MUR1620CT and MUR1620CTR for the rectifiers '

So I will order these.

Dammit, I can only get 1620CTG and 1620 CTRG.

Are these the modern equivalent?

G indicates lead free. Otherwise, equal.

Hi Perry, thanks for that. The diodes test OK. Do you have a picture that shows which is which? Rect 1 and Rect 2?
I'm going to fire this up using a headlight bulb as current regulator. Wish me luck!

Does one rectifier read 0 ohms from the B+ terminal to the outer pads for the rectifier?
