Eventually I fed the new Melqs with another pair of power transformers for output stage. I ended to run the 6C33C very-very moderately at 180V and 200mA or at 36W. I think it is little bit low and I could add 3-6W but I prefer to keep it for a time being. My previous version with 250V on plate had strange bandwidth. This lower voltage version it looks like more interesting. I get from it a moderate power but I have enough for 100dB of sensitively. I feed it at 2.4V and at full power it gave up 28.5V at 1khz. Here are some pictures:
