Thanks for that useful advice I will try it soon. A related question is can I then reduce the anode current? 20mA per side of the tube is quite a lot especially when I am considering making the second stage (5687) differential too. Even reducing it to 15mA per side of the tube would be a great benefit - I guess I would consider another tube if that were necessary - I dont need any more gain than the 7044 supplies.At this rate I will be running out of current capability in my supply before long!!
I use a D3a as my input tube fed from a S&B 10:1 stepup (D3a in triode mode). Have you or anyone else tried a differential input stage? and if so tell me more please.
