No sound in my J60

My J60 tube amp made a loud POP while jamming. All the tubes are secure and lit up, and the fuse still looks good. The amp isn’t making any sound at all though. Any suggestions on what might be the problem?

It is a JTM60 tube amplifier. Somewhat older. Not sure exactly but it’s got that old Marshall grey color on the chassis. - 21 Mar 2019 at 05:12 PM

Couldn’t find the serial number - 21 Mar 2019 at 05:13 PM

It sounds as though a power valve has blown and taken out the internal HT fuse we would recommend that you have it looked at by a qualified engineer.
