CV2799 I do not have full power output, but in accordance with 832 (FU32) adjusted, according to the performance curve, should be used in parallel after 3-5k output transformer. Select 3.5k output transformer, the optimum value should be.

Surely these tubes are a better candidate for a Push Pull amp. It seems a bit of a waste to parallel them.

Agree with you. I also do a push-pull output tube amp. Recently will upload pictures. Push-pull tube amp really better than single-ended. Unashamedly. However, single-ended output otherwise charm, it depends on the preferences of the audience.

Hello guys

I would like do this amp but only for Headphones (32~600 Ohm). On ebay I saw a similar amp and has a headphone out.

How can I implement a headphone out?
