Hi all, I love Traynor amps, and my newest acquisition is a YBA-2B in fantastic shape. It is an EL84 variant. The schematic for it can be found on this link. It is the last schematic on the pdf. I have read several other threads on modding these amps, and I have already made 2 changes. I changed the cap coming off pin 6 of V1 from .1uf to .022uf. I have also replaced R10 (220kΩ) to a more Marshall 33kΩ. However, after these mods, the amp is still too bright. I have the treble knob turned to zero, and it is still a bit harsh and ice-picky at times. Also, the bass control can't go above 2 or 3 without getting unusable. But my biggest concern is the over-all brightness. It could use a little more gain too, but first thing is first. How do I tame the highs on this thing down a LOT? I should also mention, besides the 2 changes I made, this amp is bone stock, down to the original speaker. Thanks for any help.
