Rewired the preamp signal wires using twisted 22ga solid core wire.
Only wired in 3 of the 5 inputs this time - all I need - in an attempt to reduce the amount of wire in the preamp.
Sadly, it’s noisier now than it was previously…
Well, that was a bust, sorry!
Secondaries for two heaters going to the middle of the pcb, blue wires - they are twisted together - You can try to run them separate, twisted for each heater rectifier, maybe there is coupling beetwen them when the both secondaries are twisted together... just a guess, i run them separately in my phono pre, had peviously various secondary coupling issues.
That’s all part of it! Gotta try stuff!!!Well, that was a bust, sorry!
I think, it actually “sounds” better w the twisted wires, even though I used cheap wire. It’s just the damned noise.
Feels like it’s more open sounding.
I will give it a try!Secondaries for two heaters going to the middle of the pcb, blue wires - they are twisted together - You can try to run them separate, twisted for each heater rectifier, maybe there is coupling beetwen them when the both secondaries are twisted together... just a guess, i run them separately in my phono pre, had peviously various secondary coupling issues.
