Ar t, that's a good description of the differnces between choke and other power supplies. Oddly, I am not bothered by the weight, of course it helps that my brother helps me lift the darn thing.
Regarding the hum, I have always taken care to support the amp on a good amp stand( zoethecus) and to make sure that it is not close to any analog devices. Also, I know that if i.e. a low powered halogen is on in the house that that will be a major source of hum.
The top plate mod is a very good mod for this amp though, because the choke seems to need an extreemly rigid chassis.
sirspeedy, in truth, I have not heard your version of the amp( only the single chassis version, which as I stated above, the choke is better IMHO) I would think that a dual chassis design with power supply in seperate chassis would be beneficial.
Have you A/B'ed your current amp against the single chassis choke of your friend.Does he have top-plate mod, because if not he should be recommended to get it.
