My CODE50 no longer has any output to the speaker.
 
Everything 'seems' fine, and I have tested the cables etc, with my older Valvestate and the cable and guitar still OK.
 
Lights are on, pedal on, BT connects to phone, just no output at all.
 
Any idea's?

Hello y'all,

I've been having a problem with JVM 205Combo.
During corona-lockdown, when we were not allowed to rehearse with the band, I had took my amp home with me....
As I'm always curious to find other sounds, I started experimenting with connecting other speaker cabs to my JVM. But, as I later discovered, the cable I used was no good and I think I blew up the main amplifier. I looked for the fuse, for it seemed logical to me that the fuse was blown, but couldn't find it. I also have a JCM 800 2205 head, a JMP MK2 2204 head and I've been having a JCM900 4100 head in the past. Now, all these amps were fused, so if anything went wrong, it was just the fuse that was blown. In fact, I've experienced that!
But no fuse on the JVM....is that correct? Because if it is, my problem is bigger than I thought. In that case, what was blown instead? The output transformer? My tubes?

I hope somebody can help me out on this one. And I promise never to experiment with other speakers or whatsoever.

Thnx anyway!
Cheers!
