Just checking to see if any circuit mods or tranny mods have been done with success on this amp. It seems kind of held back, if you know what I mean. I did some speaker and tube swapping with some degree of improvement, but it still seems a little thin. Can't use a 12AT7 in V1 because the tremolo uses half and doesn't work until 5 or so on the intensity with an AT7. The best tube combo I came up with is JJ ECC803's and TAD 6L6WGC's biased at 45. (Plate voltage is 396v, so that's almost 18w) I could probably go a little higher, say 48 or so.
The guy at Loud Tech's. who takes care of schematics is gone until after the 1st, so I can't get one for this amp until he returns. I'll look at changing some things around then, but figured I'd ask anyone here for some idea's/past experiences. MM or the like output tranny maybe?
Thanks for any help.
