So over the weeks I've performed a few mods, shown below
Last week I changed the coupling caps from 0.1uF to 0.022uF, the grid resistors from 120k to 220k, and the NFB resistor from 39k to 47k
Then I changed the slope resistor from 47k to 33k
(I also changed some Mylar and radial MKP caps to axial Mallorys for aesthetic reasons)
Finally I've changed those huge 1uF Orange Drops to much smaller Vishay ERO 0.68uFs
I actually made an oopsie here and heated the turret for so long one of the leads were drooping out from the bottom of the board.
Now I cbf to remove the board to fix that, so I made a J hook around the base of the turret and soldered directly to it
A bit less elegant, but it works. I might one day dress this properly.
The amp sounds great, not "better" than before, but certainly more to my liking
Currently my thoracic outlet is flaring up, so no clips yet
