It’s a great tool! did you changed the valve?? what kind of power amp do you use? thanks Link to comment Share on other sites More sharing options...
jazzyvee Posted February 26, 2023 Share 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 Link to comment Share on other sites More sharing options...

I don’t know if it was the stock valve. Link to comment Share on other sites More sharing options...
jazzyvee Posted February 28, 2023 Share 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.
