RT2/50 Tube Layout?

[Resonant Alien]

Can anyone confirm the tube layout in the RT2/50? Looking at the back of the amp, I think it's Ch2 power tubes on the left, Ch1 power tubes on the right. What about the 12AX7 input drivers and phase inverter? Is it Left-to-Right from back: Ch2 input driver, Ch1 input driver, phase inverter?

Thanks
Rick

Hi,
sorry, I didn't get it - looking from the back - the left preamp tube is Channel 2 input? That in the middle is Phase Inverter? And that on the right is channel 1 input? Or is it different?

Cheers

Got an answer from Bruce himself via email. Layout is as below:

Left to Right, Top to Bottom, looking at the amp from behind:

Ch2 Pwr Tube1 >>>>>> Ch2 Pwr Tube2 >>>>>>> Ch1 Pwr Tube1>>>>>>>>>Ch1 Pwr Tube2
Ch2 Phase Inverter >>>>>>>> Input driver/buffer (both) >>>>>>>>> Ch1 Phase Inverter

Sorry - posted a correction - there is a phase inverter for each channel, but a common input driver/buffer.
