Help me understand Dual Rec tube function

Post by parabola66 » Thu Dec 24, 2015 10:27 pm

Hey everyone,

I was looking at the manual to reach up on the functions of each tube in the Dual Rec. What I don't under stand is why the preamp tubes are split in 2. Meaning the V1 tube is split into V1a and V1b. Why is one tube split into two functions? Does this mean that it matters what pin holes the tube's pin go in, whether one side gets the extra pin, the A or the B side? (I have never switched tubes before so idk if it matters) circuitry wise.

Thanks!

A 12AX7 is made up of two separate triodes. Basically, it's two tubes in one. The socket is keyed so they only fit one way.
Ignore the hype and trust your ears. Play more, buy less = better tone.
