Hi!
I was wondering if someone at Egnater might shed some light.. is V2(b) acting as a Cathode Follower in the Rebel?

I have assumed it goes V1a -> Gain Knob -> V1b -> cascade to V2a -> V2b (cathode follower) -> V3 (a+b for PI). Would that be correct? If not, what then pls. I was thinking of trying a long plate in V2, but obviously it might not be a good idea if one triode is acting as a cathode follower.

thx!
nikki :D
 
Kinda related: What are the overall advantages to a long plate tube? Every NOS long plate I've tried in a guitar amp has just been terrible noisy and rattled like all hell.

Are they supposed to be clearer or something?
 
V2 is the first Tube V1 is the second tube. They are reversed. That is just the way it is. V1 is the cathode follower. You will be fine with a long plate. The supply is 300VDC.
 
Thx Jeff!
OK.. just to be clear on this then..
V1a is initial gain on input, and then signal goes to gain pot, then to V2?
If yes, then is V2 doing a cascade from V2a to V2b?
And then back to V1b as cathode follower, then off to tonestack, then off to V3 as PI?

If so, that is VERY sweet.

If no... then signal is going to V2 first? Signal flow pls?

RE: why long plate.. Well, IMO, it simply has a tone that is unique to it (when done well). Take a Mullard long, or say, a new JJ ECC803s. If you get one that has passed testing for noise/microphonics, so long as the gain does not get too hairy, it is one sweet sound (IMO). I am so vary far from being even a sub-guru... but I do know what I like :D Versatility is nice to have as well, and if V1 is doing initial input gain and cathode follower, then tube selection opens up a bit for V2.
