Hello smart people.
That designation is appropriate because despite what I'd like to think, I feel I have exited from that category of human being just moments ago.
I'll spare you my lamentations and backstory and give it to you straight — and in return, I only ask you do the same for me; even if it means informing me that we'll have to amputate.
Peavey special 130. Love it. Gigged it. Customized it.
I go to open it up to replace a few RC4558p op-Amps with some burr brown OPA2134PA. All went well, except i had to leave 3 of the 4 original chips in due to weird noise floor issues and another weird sound but whatever. It was cool to open it up, get at least one burr brown in there, and rotate out the chip for the reverb with the one replaced RC4558p as it was humming like Festus Haggen when it was turned up.
Mission success right?
Except I had to try on more thing: plugging in the patch cable I always have going from the fx send to the fx return to engage a completely hypothetical buffer that I heard is sometimes engaged when doing so.
So I did... except I didn't. Here's what I did do:

(I'm hoping the picture will be embedded here, but if it isn't, now would be the appropriate time to gaze upon my illustration.)
What ensued was an electrifying experience to say the least. Behold, I looked, and I saw a great thunderbolt being exchanged between the two sockets I had just plugged into. The sound it made, although I lack exact memory of it, was approximately commensurate with what one would imagine would be accompanied by the aforementioned visual.
Needless to say, I quickly unplugged the jumper.
I was fortunately spared the physical experience of this manifested power, but alas my beloved amp was not. The only sound my love makes now is a ominous and tragic hum; not all too dissimilar from the one you would hear from an hold your finger on the end of a 1/4 cable.
My only hint would be that the current humming sound exactly like the humming I got from plugging in one of the op-amps upside down momentarily, as well as the failed reverb chip. I assume this means that at least one or more of the op amps is fried.
Please, please, help me friends.
