Re: Music in a bottle: 6H30-Pi

>>plate resistance of 200 ohms<<
That's the output impedance when he has umpteen 6H30's in parallel like he does with his design.
>>but Steve Bench's data runs more around 2500 ohms<<
The plate resitance will be different depending on the op point. As you can see from Bench's data (which was quite helpful) the plate resistance varies from 1200 to 2500 ohms. That's why that parameter is usually called dynamic plate resistance. :~)
