Well Freeman.... 6505's are like buses.... you wait for one... and two turn up!

The description of a public transit system in your title screams “I’m not from the US.”

Congrats on the new amp!

Does anyone know how I might switch the channels (and the crunch mode) from my GigRig G3 ???

 

[JiveTurkey]

Does it have a weird 5 pin din jack? Or trs style? I can't remember

 

[Orvillain]

5 pin DIN.

Although I have to confess, the amp seemed a bit quiet, so I checked the preamp valves to make sure there were no odd tubes in there. They were all JJ ECC83s. Then I swapped the power tubes with the 6L6's from my Mesa Boogie. Amp was just dead silent. Power tubes not lighting up. Put the old ones back in. Same thing.

Preamp tubes all light up fine.

Might've blown a fuse or a resistor or something? None of the tubes were wobbly and I reseated them multiple times.

Anyway, will take it to my amp tech this weekend.

Power tubes not lighting up.

It's the most common failure of the 5150/6505 amps over the years.
Pins J59/J60 carry the filament/heater voltage to the power tubes, the connector is underrated for the current.
Tell your tech to start there.

I had to make the same fix in my old Peavey Duel Two Twelve. Gotta love ribbon cables!

Jizzarian‘s revenge?

Jizzarian‘s revenge?

I had that on VHS in the 80s....

@Orvillain Have you been to your tech?

 

[Orvillain]

Here now!

 

[Orvillain]

@James Freeman spot on. J11 and J12, rather than 59 and 60.

Amp is fixed.

This thing kills the 5150III

I've been trying to somehow switch my 5153 out for a 6505 or 5150 variant
