Help integrated amp is not working?

Newbee, well I get a faint audible sound from my speaker so I am not sure if the fuse is blown I am going to play with it and see what happens. Thanks!

I open here up, all the fuses are good to go. Change the tubes from left to right, right to left. There is an audible signal coming from the speaker but its not complete.

It's possible that one of the "new" tubes has a short, especially if the symptoms remained the same after installing the old tubes. If that's the case - and the fuses are okay - then there's damage to one or more circut elements caused by the shorted tube. The amp needs service.

Check your wiring, switching L&R input...does the bad channel switch? After this test, switch back the inputs, and reverse your speaker outputs. Then reverse all cables...so you run change both ends of input and speakers wires...so use your L wires as R, and visa verse.

Also, check to see that your IEC power cord is tightly plugged in. I had a heavy power cord, and the neutral [big pin] was loose, and for some crazy reason, only the right channel would act "funky".

And can you see that all of the filaments of your tubes are glowing, when powered up?

Perform a thorough visual inspection of the tube socket to ensure nothing is damaged. You could also do a continuity check on the tube pins on both channels and compare the results from left to right channel. If everything checks ok, I'd agree with Gs556.
