The things we find in amps

[J M Fahey]

The sickest thing found in an amp was a very,very thick layer of gudrons. The amp was recovered from a smokers tavern and on the top cover inside arround the vents has a few mm. layer of gudron like something real exploded inside...Geez. Still wonder why still I smoke... Looks like someone put some mud inside...Thinking all this gudrons deposed on pulmons...very scary

Had to search a little
"gudrons" (in French) means "tar", in this case the tobacco type.
I do not smoke, and for good reason.

My Father was a Doctor, and being curious, I watched the films Pharmaceutical/Medical Companies sent him.

I saw a smoker lung slice side by side by a non smoker one: one was pink and flexible, the other was dark brown, almost black, but the main point was that it cracked when flexed.

A friendīs Father, chain smoker, was operatd: they opened him up, and started scratching his ling tissue with a small hook/spoon tool.
Whatever remained attached , stayed; whatever crumbled and cracked away, was removed.
They removed one and a half lung , and he had to permanently move to one of our mountain Provinces (think high in the Rockies)
He lived 30 more years after that, so clearly that was good advice.
I guess his bad lung tissue was encapsulated in crackling "goudron".

And "pulmons" are lungs, I think.

Not to worry, it's all good. We're learning too. In the meantime I'll stick to savory croutons and grey poupon.

As for things found in amps, everything from cockroach motels, rat turds & mouse nests (ecch!) to an envelope with eight $100 bills. Inside an old Sony reel to reel tape recorder, packed with "kandy korn," some mouse's prize stash of candy.

I thought so as well as pulmonary diseases like pulmonary fibrosis, for instance, is an English medical term why not pulmons aso?...Sort of gansta medical slang
Allready edited myself. Peace

The tubes are referred to as V101 - V103 on the pcb overlay -I wonder where they were expecting to fit the other 100 (just in case there's an awesome preamp that needs squeezing in there)?

I think the hundreds digit may refer to a layer number, but that's just a guess on my part.

[Justin Thomas]

In Fenders, usually 1-99 are mounted on the main PCB, 100-199 might be on a secondary PCB, and maybe 200-299 might be chassis-mount. Or some such system like that. The few large 70s Ampegs I've seen do the same. The service manual will let you know their system, if you can get it...

In the case of V100-103, maybe they assigned the sockets those numbers for ease of remembering. Which amp are we talking about for those designations?

I once found a screwdriver that I had lost, in the back of a customer's amp. It must have been sitting in bottom by the reverb tank for a couple of years between servicings. I was really glad to find it, it is still one of my favorites.

Found the skeletal remains of a small gecko inside a Vox organ once. Also found the skeleton of a mouse that had taken up residence inside of a Leslie cabinet.

Worst was a Peavey 212 Classic that became a bug zapper when a large roach crawled across the high voltage traces of the power tube board.

Oh, I thought you were being funny with the V101 thing.

It is common to break up part numbers into series. Like the preamp is all 100s the power amp is 200s the power supply is 300s, the digital is 400s. That sort of thing.

Hartke does that, preamp 100s, power amp 300s, power supply 400s.

I once wrote an article for a magazine about servicing things without schematics, and that was one clue. Part numbers broken into series for vertical, horizontal, video, power supply, etc.

Peavey has a few models where all the parts are R1, C3, etc, except one small aux board for power supply, where they added a 1 ahead of the numbers, so on that board: 1R1, 1C3, etc.

Some drawings have a fresh series for each board, but they all start with 1,2,3. So there could be three different C1 in the amp. I'd much rather see C101, C201, C301.

Quotes on the circuit boards, you'll find those also in THD amps ...

Here's the THD Univalve board with the famous Zappa quote:



There's also another THD PCB that says something like, "all of you point to point homos can kiss my lilly-white ass," or something like that. I can't seem to find the photo now.

Hey Bob,

That "other" THD quote you seek is in post #37 of this thread.

Justin

Edit: Whoops... seems that was VHT. But is that the one you were looking for?

[DrGonz78]

Worst thing you could find in an amp??

that must be it. i thought it was THD. they say as you get older the mind is the first thing to go...

[Enzo]

No, the first thing to go is...um... the first thing is...uh.. I don't like walnuts.
