Fender Stage 112 internal help? (Need a doc)
Hey all, got a question. :eyes
I have a Fender stage/112 amp that I'm going to attempt to repair myself. (Should be easy)
Ok, my amp has sounded fairly crapped out, noisy, out of sorts for some time.
I decide to take 'er apart for a thorough inner cleaning & tuner "spraydown".
When looking at the circuit board, I see 2 resistor/diode (or something) side by side thingy-ma-jigs, which appear to be "Fried to a crisp"
Don't know why, or when exactly, but I did do a gig (inside) during a nasty lightning storm once, & the god's hit really close & I could feel the tingling through the strings. (yep, the beer was cold too)
Anyhow, I was wondering if I were to take a few pics of what I see, & post 'em in hope that someone might tell me what they are, where I may get them, & what do you think the poss. cause was?
It might have happened some other time, or an on-going thing, not sure.
But, I would like to fixer up & get it running again. (It's a decent practice amp)
Any help, greatly appreciated!

Wow...TOASTY.
According to the schematic, those are 47ohm/5W resistors off the emitters of the transistors Q1 and Q2. I don't know a whole lot about transistors, though, so I can't give any more information other than what I read on the schematic.
Chances are the solder pads are also toast, so there will likely need to be some wired jumper connections in there for the fix.

Aside from those burned up resistors, it looks like all of your tubes are missing!
Seriously, I'd clip those resistors at their leads, leaving long anough leads to solder to, check the leads for continuity to the next component, and if it's fine, solder new resistors in their place.
Of course, that doen't solve why the burned up in the first place!

They are 47 ohm 2 watt resistors. I would check and make sure that c49 is not shorted.

Thank you for the replies, this will give me a good start.
Yep, lost my tubes somewhere, for now..........:)

Did you sort that out.

No reply in over 15 years. One might think a solution has been found by now.
