Default Re: Rewind Dynaco mains Tx for 240V

The only thing I would add is,
Try and find true enamel insulation rather than wood varnish AKA polyurethane.
DO find and use onion paper as interwinding insulation.

Somebody said to add a thermal fuse, I would say DONT add a thermal fuse.
Use fuses on primaries and secondary HT ( you shouldnt need heater fuses ) .

When actually testing the amp will be the time to start with say 250 mA on the primary and go up from there. If you go crazy mad and add 100's of uF on the secondary, you will have to determine the correct fuse by trial and error.
