modding a S.E.X.

[punkaroo]

Thanks Doc. I wonder if I should just hold off on tube rolling until I can either:

A) Feel comfortable enough to do it myself, or
B) Find a local DIY-er to do it for me

I wonder if rubbing alcohol would take the AVM stuff off? And since I'm an idiot, where are the transistor heat sinks that I might try to scrape this off myself?

Thanks again!

(I think I'm going to have to have a look at that CD-ROM I got with it. I'm stuck at home, post operation...so I have a lot of time to kill for the next few weeks!)

If the AVM stuff is latex as I suspect, it should just peel off.

LOL! That's awesome.

I wish I'd known a bit more about this stuff before jumping on the amp. Seems like a pain.

Live and learn I guess!

Doc,

The AVM appears to be something more than latex, though I suspect the latex is the matrix in which the other stuff is mixed.  I have some AVM and it's somewhat gritty/chalky (depending on thickness of coat) to the touch, and tends to chip or flake off, not peel off.  The texture reminds me very much of Silent Running 1000 -- the vibration damping compound used in engine rooms on power boats.  Anybody have access to a GC or spectrograph?

I can say that this stuff does work as advertised on signal tubes, but coating the whole underside of an amp seems a bit extreme to me.

Then my guess would be that it is maybe latex loaded with silica. That is what we used to put on the Straight 8 driver frames - what I called "secret sauce". Then we found the 3M damping tape which worked much better. That is what I would use now if I wanted to damp a chassis.

Doc,

That makes sense to me.  Anyplace where this 3m tape can be bought?
