...I see 2 burning power tubes! (They weren't burning but they were pretty red inside there; 2 out of 4). There was no bar though, it happened in my room so gladly I wasn't jamming when it happened. Is this what they call red plating? The amplifier is pretty new, so what could be possible reasons of this event? I noticed the tubes when my volume drop suddenly in half and I stare inside the JSX all of a sudden...Holy Sh*t!

So I'll probably need new power amp tubes, could I drop some KT77 in there?! =o

I asked since I just read about it somewhere in an old post right before my amplifier going haywire on me. .....

It was your post! Coincidence? I don't think so.

Anyway, I had them in a Rivera like 2 years ago and they really open up that headroom inside the amplifier..so I'm curious. Anyway, just turned it up again and all 4 seemed normal but I got scared enough to turn it off before a minute passed. >.>

Check the bias on your JSX, sounds like what Becky said.

Will do. Right now, I turned it up and it sounded fine on the clean channel with no redplating sightings. However, it started to produce a "pop" (after both the power and standby switched were flipped) sound from the cab, very similar to a heartbeat. It started really slow then it started palpitating faster and faster. I used another guitar cable and still...

Could the cab be part in this? Its an old Laney from the 80's.

Running a cab at the wrong impedance will do it and so will incorrect biasing.
