I just finished two channels of opa549 non-inverting gainclones and now I am planning a tube buffer for them.
I could really use some information about the schematic of the buffer. I am plannig to use the same tube/tubes as Joe Rasmussen (6922).
If I got it right, the tubes have dual triode, so I need only one tube for two channels, right?
And I am not going to use potentiometer in front because I have separate preamp.
Am I right if I connect tube pin 3 to the input of the right channel and pin 8 to the input of the left channel?
Then pins 2 & 7 to the preamps outputs without resistors of any kind?
Do I have to put anything between the tube and the input cap?
