Hi I want to know if anyone has tried this before. I have run my mark 2 in ultralinear and triode straped. I like the sound of it much better in triode as I think it sounds closed in the ultralinear mode. I need more power and think pentode/tetrode might be a good comprimise.
It looks as if I will need to supply the screens with about 350 volts and adjust bias as needed. Also to keep it stable I may need to limit forward bandwith and adjust feedback.
Any thoughts ?
Regards Fred
I have a eico st-70 that sounds very nice and uses the same basic circuit configuration that the updated mark 2 does.
