||Re: EF86 input tube (wow!)|
I did what you suggested and it worked just fine. I'm very happy with the results and I didn't have to touch a component, just install a new 9 pin socket and reassign the wires. I got ahold of some real good spec sheets that confirm you can use an ef86 with the same combination of components etc.. that work with the 6sh7. I appreciate your input.
I know that the 6sh7s are terribly, terribly microphonic. (I tried 8 different tubes and every one was!!). I keep hearing that the ef86s also tend to be. Do you know to what degree as far as percentage?. I ordered a couple Svetlanas from AES because that is what I used for the test run. I borrowed it out of my DC30. I hope I don't have to go through a bunch to find good ones. Thanks again.

I have no idea about percentages but I've been led to believe that of the NOS ones a fair percentage. I bought my EF86 from Triode Electronics ($10 I think) and Ned assured me that he pretests his tubes for microphonics. I'm sure Lord Valve also pretests his as well so either of these two sources seems like a safe bet if you want to try to minimize the chances of getting a microphonic tube. My amp is a head so vibration is less of a concern.

Thanks again. If the Svetlanas don't work for me, I'll try your suggested sources.
