Hey all you Marshall DSL40C owners I came up with a very nice warm and smooth sounding preamp combo.This tube combo seems to really tame the gain and fizz on this amp.It makes the gain way more usable in the Ultra gain channel lead 1 and 2. In V-1 I have a JJ ECC83 MG(Mid gain).In V-2 I have a JJECC83-s.In V-3 I have a JJ 5751 (70% lower gain than a 12ax7).In V-4 I have a Sovtek 12ax7 LPS. To take care of any microphonics I have two rubber o-rings on each preamp tube and I also have one large rubber o-ring on each power tube.My power tubes are TAD EL-34'S. Try this you will like it.It is a slightly darker combination.However, it makes the treble knob and presence much more usuable along with the gain.
