Technician for guitar amplifiers in MTL?

[Smoker14]

I need a technician to check out and repair a tube amp that won't turn on.

Do any of you have any recommendations for guitar technicians in Montreal?

Thanks!

I don't know anyone there, but any competent amp tech can handle this. "Dead" is generally the easiest problem to fix. Far easier than "Distorts sometimes". And tube amps are simpler than solid state, that is why you see guys who "only work on tube amps".

Tube amps are mainly different: I don't see all that much more simplicity, particularly since most solid-state amps nowadays use opamps which hide the trickery of low-noise BJT input stages. And the high-voltage low-current circuitry of tube amps is less compatible with loudspeakers and human well-being.

Of course class D then is a different beast regarding servicing. But the Peavey stuff I've seen so far is class B in the power stage, possibly AB (the transition voltage gap is kept rather low).

Tube amps are mainly different:

Different from what? Each other? I'd object. Different from solid state? Of course.

If I drew you the power stage of an amp with two (or four) pentodes, but no values, would you be able to say it was a Fender? A MArshall? And input stages, let me see, a triode, 100k plate load and 1.5k cathode resistor. SOund familiar? Change those to 220k and 2.2k. ANy real difference? (Other than sound) Circuits are circuits, and seen one, seen them all fits tube amps for me. Fender eyelet board versus Mesa crammed into a pc board, sure those look different, but the circuits? Straight out of RCA.
