Hello, I got a situation here, any tube experts could help me because I THINK something is up, but everything SOUNDS fine :
I own a 3-month old Peavey Triple X, and I've gigged it 3 times no problem. the amp is noiseless, doesnt hiss AT ALL unless cranked to 11, and the tone is so good, I plan on selling my Sansamp PSA1 because of it.
Here is where it gets weird : There are 4x sovtek 6L6's in the amp, and yesterday I noticed 3 of the 4
power amp tubes glow with a beautiful "Blue" inside the glass, but one of them does not. All 4 do light up when the amp is on, but when turning off Standby, that's when the blue shows up. I switched tubes around to see if it was the tube, but alas, it isnt. It is the tube socket closest to the 12AX7 that "drives the power amp section" (I could use the word rectifier, but....)
I asked James Brown (the man who invented the XXX, not the Godfather of Soul) and he said something about a "blown open resistor" in the socket? What does that mean?
Also : I just got done playing through the amp and noticed that the plastic grille above each tube is HOT except for the tube socket that DOESNT have that beautiful Blue glow.
Not any pressure, but I have a gig in 12 hours, and I'd really appreciate some help, advice, etc. Thanks :-)
