Hey Black and Dark,
Thanks for the interest in helping me. I did get the manuals but the first one was sys11 and the other 2 were sys 3-7. I didn't see anything about the bells circuit, I can't find any info on the bells circuit anywhere.
I did buzz out and made sure it was going to the backbox. I saw that the red wires that connect to one side of the bell buzz out on every red wire on every connection with red wires in the back box so I assume that's good. Then the other side of the bell is a brown wire and it goes to a connector j2 I believe, it also buzzed good. The j2 is on the CPU board. The weird thing is this is the second CPU board I have tried and the bell didn't work on either board. I know it could happen that both boards have a bad transistor but it sounds weird.
Also I'm not sure that the circuit runs to the CPU board.
I did read somewhere that another guys bell was stuck on and he found he had a fried transistor so your guys theory sounds right on the money but I think my ignorance isn't letting me find it.
When I get on my lunch today I'm going to find exactly where the transistor is.
Sorry for typos, I'm using my phone.
Thanks again for your help guys.
