Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: SE 2A3 beta follower : spectrum graph @ 1W , finals biasing

I had the amp on some Optimus ProLX5's , not full-range or high EF.

They were just workbench monitors for my tube amps played nearfield at lower volumes, hardly demanding by any means.

In that application, the circuit sounded alright.

But I was more interested in the objective performance of the circuit, which I have discovered is poor in terms of THD.

No doubt, the biasing is a problem, as Tre noted.
