There are not many resistors in the amp, so we can try some nice parts, I guess. At least I would try PRP and these naked TX2575(but I do not like the idea of a resistor without a casing, though :-).

It would be great to make GB for SumR's and resistors, you can count on me, Buzz! Thanks :-)

Good day all. It's superbowl Sunday, a national holiday almost here.

All of the paid F6Convertible board payed orders have been sent.
If you did not recieve a stamps dot com email notification, let me know - so I can confirm it is sent.

I do have additional boards available as well if anyone is interested.

Tea.

I am psyched!!! My Cinemags arrived on Monday and I ordered all the stuff from Mouser yesterday...should be delivered tomorrow.

Just need to tap some holes in the sinks and I should be good to go.

Only major issue is that I am using a PSU designed for a different amp. Currently it runs at 32V running at about 150mA per channel. Jacked up to 1.5A per channel I suspect around 28V according to PSUD.

I have enough jfets to run cascoded, 28V will be pushing it for the 2sj's.

What is the VA rating of your toroid? 28v wil not hurt the FE Jfets at all, assuming you degenerate them.

Maybe run two pairs parrallel and degenrate them. But I would not let the voltage be the limiting factor.
Just bias lower to start.
