Sadly the pp35nn is ony 2.4 watt pp.
The 300b looks very worthy; I have a matched quad. Just one quad but some other matched doubles, so could make an amp to last to my end of life.
But anyway, the 2a3 figures look worthy at 10 watts, I could put a quad of 6b4g’s in.
Yes, probably that; 10 watts.
Then the gm70 se 35+ watts.
