For Croatian "Triode Festival Zadar-2016" I made a little and compact stereo integrated amplifier with tubes 300B and 6GL7.
By adjusting the cathode resistor to ~ 890 Ohms got current ~ 78mA through the output tube and power output ~ 7W.
The output transformers I rolled himself, but the power transformer and choke I took from old disused devices.
