They are very closeThe problem is that the caps are next to the regulators (trannies) , and the heat from them dries out the caps.
Interesting. In the early 80ies built quite a few clones with various improvements, mostly in the PS . Cannot see how lat fets would address the weakest features of the 3020: bass and dynamics.

well the last one i did certainly improved the sound,IMO anyway, and ive listened to alot of these as ive repaired them over the last couple of years
I certainly appears to make the sound 'cleaner'
I agree some can sound 'wooly', but they all seem a bit different to me everytime i listen to one
certainly not as good as the 3103 IMO, the tone on those is realy good, again IMO.
and its all down to the individuals ear as well i guess

Our first mod to these was running some wires out the bottom and attaching 2 really big (the size of a BIG can of Arizona Ice Tea, 100k µF total[?]), crude but effective, made a serious improvement.

I'll be diplomatic and reserve judgement I think I would want to test it first.
You could rig up a transistor on a heatsink and power it from a variable PSU adding a resistor from C to B to turn it on a bit. When you have a voltage and R value that generates some heat try adding a layer of that padding and see if the heat is transferred very quickly to the heatsink.
