New Tung Sol 6550 vs KT120 vs KT150 Sonic Comparison

You just need a good pentode kt88 amp, with regulated screen supply, no need for kt120 or cathode feedback.

I would never buy less than a lundhal 60 Watts + output transformer

The OT is the most important part, all the caps are not influential at all.

Ideally the Power supply caps should all be 100% film and around 50uf + 200uf, for the kt120 I would go to 100uf input and choke and 400uf.
