Well, I find this about as simple as is possible. Even with 6A5's a 10-20% E-Linear/g2 tap has worked well. With a test-mule amp built with E-P OPTx, 50% E-Linear was still an improvement over none at all.
20% is probably a good one for a light touch. It flies in the face of no nfb for DHT's but there it is.
The E-Linear circuit has a bit of PS simplicity on its side too.
With Guinevere, running 5687's for gain, another 5687 would work quite well for the front end. there's too many triodes to list that I have tried or bracketed with this circuit. It is really easy to pick for...
regards,
Douglas
perhaps an amp thread ought to get started?
