Dude! Do you know how extremely lucky you are to have the matching cab for this thing? I have the exact same amp and love the shit out of it! It can capture almost every sound there is - country, blues, rock, and metal. Such a versitile amp. I am really envious that you have the actual matching cab, Cheers!
A good amp with overheating problems because of the "fixed bias" setup.
I've had a couple of JTMs, a JTM60 which kept frying the power transformer and now I have a JTM30 (2x10). My local tech Valve Heaven @ Surry Hills, fixed the problem by installing a 'bias pot' and then resetting the bias. The amp sounded better than it was when new. You can take the mod a bit further by installing a cooling fan and a set of Groove Tubes but all in all these are a great little amps.

@TonyBurke100 I used to have this amp too. I fixed the overheating problem just by removing the tubecage. never had any trouble after that.
