surprise....
i tried to get down k2 with the Edcor with the trim pots and it did not work. The smallest distance I could manage was 10db. I tried both secondaries lower and upper.
So the Edcor seems to have a k2 dominance build in and you can not really shape your sound man....
My difference in sound was coming with cap placement. Did you use source resistors or go the naked route posted by ZM. I stopped with .15r on both, with one cap connected directly to sorce on one fet. Cant remember now. I wonder if zen pot works more successfully with larger Rs values, where it would affect gain more.
generg, perhaps in this case, it might be easier to dial in what you want using lhquams love-pot method instead of loading the tx secondaries....if u use small Rs (0.1R?), the effect on class A availability and gain would be small but you can still tune H2 mix and decide also whether you want it on +ve going vs -ve going phase.
Anyone thinking about F6 PCBs?

For which trafos ?
Maybeso master ZM can tell us where to find some ISKRAS....heheh
..you thinking about Papa standard Jensen ?

.....
no way , Jose .......
unobtanium .....
what else ?
buzz can buzz is Onetics same in physical layout
BudP have all my trust
ceeVee nailed it. Pinouts are different, at least on the Onetics vs Jensen. ......Then again, I will hae to look, cause with the F6, you can do all kind of crazy things.
Point for point, they are different. Flochini will be listening to Onetics soon, So i think we will get even more back up for Bud's xformers. Cant work on speaks for various reason, so might try to setup measurement rig and get some numbers on the Onetics system, since evrybody loves numbers around here.

heheh just checking if u were checking ZM.....i know it's unobtanium...nice pair sold some time ago at your nice forum.
Must be some of last ones floating around.
Then we will need a PCB that will allow us to do these crazy things.

rom the top of my head, how about some jumper pads for the trafo connections that we can wire to connect them according to the pinout?
Extra pads would be fine, long as the Jensen can be mounted on the board since I imagine most will opt for the original X-former.
