Hi,
i built myself R47 preamp and found out that the output tube (E88CC) runs on limit of dissipation, and also get very hot. Anode resistor (8k2) also get too hot to touch.. Anyone else experienced this problem?
It sounds very nice this way, but i'm worried about burning the tube too fast if i leave the circuit as it is.
Is there anything i could do about it and preserve the sound? Maybe use lower B+ or more resistance on anode?
Another problem is finding non-inductive anode resistor, 8k2. Which easy to get values i should use in paralell to get 8k2R and at least 6 to 7W?
