Just blew a transformer

[Casper]

Another reason to like the Axe Fx. While cranked and shaking in glorious overdrive, my combo amp's power tube (6v6 EH GT) heater shorted to the plate today, taking out the transformer with it. Sudden silence and a nice burnt smell.

On to cranking the Axe-Fx, it neither shakes nor stresses, yet still produces beautiful tones.

joking aside, I was reminded of the convenience of a box sans tubes etc while at store other day and several of their high end amp heads were down with various issues

Bullwinkle really appreciated the proper burial they gave to Rocky.

The heater couldn’t have shorted to the plate as its inside the cathode.
Even the cathode shorting to the plate seems unlikely as the control grid and the screen grid are much closer to the cathode and in between the cathode and the plate.
Did you measure across the screen resistor to see if it was open?

Yeah, not sure why they are shorted.. maybe something rattled loose or arc damage. I pulled the tube and measured across the pins. Heater pins 2, 7 and plate 3 show continuity. No continuity across the other pins. No screen resistor, Blankenship with Fender Princeton-like circuit. The tube and the socket both definitely smell burnt, but nothing immediately visible. Will have to check everything out. Appears the EH tube failed internally.

While a tube amp offers a different musical experience than Axe Fx III, it is kind of nice that you can push the models hard in Axe-Fx if you want and not worry you are stressing the virtual components out.

Did the speaker cable short out?

Similar situation, but rather ironic where my band mates were trying to show me how much better a real amp was than my AX8 at the time. I just sat back and smiled. Smokin' Amp Head

Smell of burnt transformer in the morning

Well, I'm now officially tube-free. Sold all my tube amps in the last weeks. The Fractal stuff sounds better, needs less space and has less stuff to worry about ...

I should have gotten my FM3 nearly 2 weeks ago, but seems like there went something wrong ...

Ha ha ha … <AvE> She let the smoke out.

Definitely does not smell like victory....

lol "it sounded good for a while"

I had way more bugs with digital stuff than with tube amps in my whole life . Everything can go wrong

Seriously? When does that ever happen?

Tube amps are fairly simple circuits... They can't really have bugs because they aren't running code

Two completely different things, in my opinion.

Not me. My amps and pedals were always nothing but trouble.

That’s why the legend that tube amps are fragile … yes, if you play football with them. Never had a single problem with hundreds of gigs

Zero problems with Mesa heads . Like ever “s*** happens” , same with pedals . I always got 10 pedals in the floor and zero problems . Only the short cables while kicking on it .
