re: 480A

I write from Italy.
I have a problem with a Scott 480A, just turned on the Vmeter go to scale and remain there.
Sound is heard but will sometimes feature the protection relay.
I found that two transistors get very hot, Q13 and Q14 are.
I know someone advise?
Thank you very much.


Thanks for the manual. If by any chance there is a way i could get the schematic diagram please let me know.
