I am new to tubes, so bear with me. I replaces the 4 KT88 tubes and the 12ax7 tubes because the right channel fails to play sound. The fuses look OK. I have not, nor do I understand how to, checked the ceramic fuses. How do I continie checking to see what is the problem Thanks!

Do you have an oscilloscope, DVM or any test equipment? If so, you can trace the signal from input to output to see where it fails. If not, you might try swapping components and find it by a process of elimination. Try tubes first, capacitors second, and transformers and resistors last.

Does the amp work properly? If so, I'd probably use the smallest value fuse that will work at full power without blowing. If you have a meter, you can insert it into the circuit where the fuse goes and measure the current. If not, try a relatively small value fast-blo fuse at first and work your way up to a value that doesn't blow.
