It’s a great tool! did you changed the valve?? what kind of power amp do you use? thanks
jazzyvee Posted February 26, 2023 Posted February 26, 2023 No i have not changed the valve. In the past i used a QSC PLX 2402 power amp. Which is a superb amp. But it made my rack far too heavy. I now use a Synq 1K0 stereo power amp. Though they aren’t produced new any more. 1

I don’t know if it was the stock valve.
jazzyvee Posted February 28, 2023 Posted February 28, 2023 (edited) I wanted to change the valve in mine a couple of years back but the ones ordered did not fit in the sleeve on the F-1x board. Eventually i found one that fitted but the problem i was having wasn't due to the valve, the preamp needed a new transformer. i kept the new valve as a spare. Edited February 28, 2023 by jazzyvee
