I don't really understand what you are asking for here, other than you are looking for a good amp. You say that you never heard an amp you really liked, and that you even rebuilt a vintage amp and didn't like that one. Now you want to try and rebuild another vintage amp?
If the above is correct, I recommend you don't do anything until you actually listen to an amp you like. Doing anything else, just doesn't make sense.
