I’ve re-valved the amp, sorted out a few minor issues (it is 40 yrs old after all) and had to replace the original Celestion drivers with some new ones. I chose the new G12M Greenback and a Vintage 30. Unusually for a Marshall of this period it has a reverb tank fitted as standard.
I have found myself running this amp standalone as a platform for fx and been very pleasantly surprised.
