Pat, from memory, your 2A3 was once cathode biased. If your circuit diagram is correct, the bias circuit, which was once attached across the +/-ve legs of your filament, have been removed. As drawn, your 2A3 is not biased; no wonder your amp does not produce music. I vaguely recall explaining this in a past thread.Making significant circuit changes requires basic knowledge - so you know what is safe, what should work, and how to ask questions. What you are doing now is a crap-shoot. It can be dangerous.
I am simply not confident that you have sufficient knowledge not to be putting your loved ones and yourself at risk. I can't responsibly provide any advice to you - I won't be complicit in what you are doing.
Take the time to learn some basics. Please.
Edit: I should add that for non-EEs, learning the basics can be challenging (people learn differently). I'm sure inmates, including myself (where I can), would be more than happy to help explain the key concepts where required.
