Need to fix Alto TS115A plate amp - distorted low ouput
I have an Alto TS115 power PA speaker. I tested the woofer and high frequency driver and they are fine. I took the amp plate out and inspected it visually under plenty of light and magnification and can't see anything obviously wrong such as a swollen capacitor. How can I find information on how to troubleshoot this problem? Thanks.
Is dit een goede vraag?
