Can anyone confirm which Preamp tubes V1A V1B V2A V2B are used or active on channel 1 clean for this Amp.
Or a better understanding of the function of these tubes in this amp would be much appreciated.
Amp is a Lonestar Classic 100w Thankyou...

Ah, just read your earlier post and see that you have the Lonestar special, in which case your manual is this one....

Hi
What if id like to change the preamp tube for channel 4 od2.
Which one is it?
I have S1 104 el34 but I guess preamp valves positions are the same.
ThankYou
