I have some questions about the 300B version:
1) All else being equal (same brand output tubes, etc.), does the 300B version sound better or worse than the 6B4G? I can't find any answers searching this forum
2) If I only use the standard specification 10 watt output transformers with the 300B version, do the output transformers run really hot, sound distorted, etc. In other words, are you pushing the envelope using 10 watt output transformers with the 300B?
3) with the 300B version, is it 410V plate voltage and 60 mA plate current?
