Hello again,
I replaced the filter caps on my Traynor YGM-3, and it sounds killer, while I was at it I removed the .1 capacitor that was wired to the Negative Feedback resistor. I took a chance and fired it up, here is what I noticed
a lot of hum; i flipped the ground switch and that issue was quickly solved
as i turned the volume knob it seemed to get its loudest at 5, staying stagnant til 8 and 8 with a ton of headroom and suddenly gets very compressed and distorted from 8 to 10, a sudden jump.
I'm now wondering, did I wire something wrong in the filter section or is it the NFB that I altered doing this? The original schematic called for 4 40 section of filtering but I have 32/32 for the preamp and 50/50 for the power...I really hope I got this right...
Another thing (maybe needs a new post), but im looking to install a 3 prong and bypass the circuit reboot and ground switched and add a bias pot. I have added a bias pot to my non reverb BF princeton with great results using the torres method, but how would I go about doing this on this amp? I assume bias resistor attached to ground/chassis or back of pot, wiper coming from bias supply on tagstrip and outer tab attached to where the bias resistor used to be? I still want to have the tremolo which is bias powered as well...
sorry for all the questions...help me get out of noob hood!
