+18 rail= 38V AC

+11 rail= 24,8V AC

It sure does not look right, even for my electronics untrained self!!
Hi there, it sounds to me like you have lost your regulation. Possibly filter caps, a voltage regulator, or a bridge rectifier. I would start there. If you don’t have the ability to check it find a tech in your area. Hope all goes well cheers
