(I started a new thread for this so as not to hijack the other one.)
I was tring to help Coriolis with some pin voltages.
well, I went to measure V's on mine, and found out that I was in the same boat, funny how stuff just stops working.

There are a few differences to take in......
I am using tlo82
I am using a 12v supply



alright, check it.........
With the probe I had signal all thru the audio path till I hit the 555.
this is the third 555 I've fried!
I replaced it.
Thinking the P.S might be a bit much I brought it down to 8.48v
so here are the pin v's for both IC's

TLO82:
1) 4.18v
2) 4.19v
3) 3.88v
4) 0v
5) 4.11v
6) 4.37v
7) 1.17v
8) 8.48v

CMOS 555, these measurements are at "idle", as in......no input signal .......the 555 is not being triggered to "do the do"
1) .1mv
2) 14mv
3) .9mv
4) 212mv
5) 5.64v
6) 14.1mv
7) 14.1mv
8) 8.48v

does this circuit eat 555's like crazy? or am I rockin 'em to death 8)
but seriously I did make a few component changes from Mr. Hollis' suggested values.
Which Might do it, as far as the rockin' it to death thing.
the 150k input resister Was dropped to 27k (alot easier to clear the gating with out a preamp)
the 1meg betwixt pins 5 & 7 was dropped to 470k (actually can't remember why I did this, but I did it so.......)

Anyone?

the data sheet for the TLC555 tells me that it can take up to 18v on any input so.............
unless the massave boost of the opamp/square wave section is exceding 18v?

alright,
So I'm starting to clean-up, cuz I'm going up north to see Couch Flambeau & Shellac, and then help a friend build a Two story garage.
I figured I would lay out some basic tracks to take with me and then "re-work" them with some friends while I'm there.
Anyway, I'm really getting in to this one Idea and think....." this would be a great spot for the Crash sync............."

I got half way through the part/section and.........................

Well, that was my last 555!


DEATH TOLL=5

does ANYONE have ANY idea as to why I'm killing these things at such a fast rate?

















please.
