For HF channels only. Still with shaft switch diodes and properly implemented input choke filters there is not advantages of tube rectification, quite opposite, and particular for the LF.

I am quite interested to build a pair of these amplifiers to see whether certain conclusions I have drawn about what has been good and bad in amplifiers I have made in the past are valid. I've usually found valve rectifiers to sound preferable. I don't normally like huge reservoir caps. The Melq has lots of features I'd shy away from usually which makes it intriguing.

Well, if you are wiling to build a pair of these amplifiers then you will be able to drive output tube with any current you wish. I still feel that at 320mA you necessary burn the tube. Also do not forget that this is a fixed base and the infamous 6C33C temperature stability. I personally feel that instead of driving the tube with huge currents it is better to get more sensitive speakers with higher transient capacity.

I'm also a little concerned because I don't like the fat 'tubey' sound of the 834P one stage of which someone else pointed out was operating in less than ideal circumstances.

I’m not concern. Moreover I find that all the rest my phono-correctors are too fast, too “gipsy-sounding” and I am getting rid all of them leaving myself ONLY with ET2 connected to 834PT. Generally, if you care to add some “vigor” and some nervousness to Milq then it might be gone but boosting the plate current but I do not feel that it is necessary.
