SUT - electrical theory and practical experience
Hi @intactaudio , Finally, the overload points (1% THD+N) for the 834P were 69.2mV at 1kHz, 260mV at 20kHz, and 7.85mV at 20Hz.

Question About Capacitor Upgrade in Tube Amp
Vcap CuTf are great for 300B SET - clean, clear, transparent, fast, soundstage not harsh at all. Duelund Custom are excellent too - great tone harmonics, soundstage, a little bit slow and full bass. Bu I think these two options are too expansive...
