Default Building a 5 valve A.C. amplifier from scratch

Hey like minded people.

Decided to jump on a project, to build a simple A.C. high fidelity amplifier using the 5 tube schematic from the Practical Amplifier Diagram. Why? Because I want to know more of these, I want to learn more on this and I would like to have a great amplifier.. also, I have many parts lying around. Instead of bin it, would like to use it.

I had a slightly similar amp purchased last year you guys ( Lawrence, Herald, Bill ) helped me a lot with that.

Just to understand this schematic correctly, could you please help me to understand the potentiometer and the diagram attached.

1. R10 variable resistor. The wiper and the pin 3 is connected through the capacitor C6

2. R12 wiper and pin3 are shorted.

I hope this is correct.

If you have any further advise what to be aware of or any good hints, please let me know

Thanks dudes !!!
