The Luxman 3045B is outstanding. Aside from the usual periodic maintenance (re-caps, resistors, etc.) the circuit is sound. I used these for a couple of decades with a stash of the original high power triode tube.
With this amp, you're pretty much at the limit of push-pull sound. The transformers are beyond reproach. Instead of trying to make the Luxmans something they aren't (you're already a half-step back by the conversion to KT88s), accept your amps are sensational and consider your next step moving to an 845 SET or P-SET 300B amplification.
