I have a QFT and want to dial in secondaries. I opened the adjustment screw 1/4 and it made a positive impact. Any tips on how to find the sweet spot for vacuum secondaries?
Put a paper clip on the vacuum pot rod right up against the pot and see where it ends up on a full pull. If its pushed all the way down the rod, you know you opened up. you can put a tighter spring in there and see if it helps and you still get full opening, usually helps with a bog to troubleshoot.
