Well, I fixed the TKO 80 Bass Amp I asked about a while ago.  IT seems that a Cap (50V, 2200uF) had one of its leads come loose. Well, I resoldered it (after driving to the bank, buying a soldering iron and solder) and then plugged it in... forgetting that i'd detached some plugs from the board... that found themselves shorting to the chasis... which was in contact with my hand when i plugged it in.   Wow.  That was fun, almost as fun as the two car accidents I almost got in today.
Peace 'n Love

Whoa !!  :shock: Close one !!! Glad you're OK. Just keep repeating - "one- armed technician, one-armed technician"

Well, don't feel so bad. When I was building my last tube amp, I shocked myself several times on the IEC socket that had the cord plugged into it, which was plugged into a power strip (which was plugged into a wall receptacle) that I forgot to turn off while I was poking around inside the amp. My reaction was to instantly pull my hand away, as I know that feeling of being zapped by 120VAC.  :wink:

(I been shocked a few times before)

I'm sorry that you got that lesson in that particular way. It's no fun.

I've been shocked by power line accidents five times in my life, and I remember each one clearly. Every single one except the first was because I did something that I knew better than to do. The feeling of "Why did I **do** that??" is so strong you can taste it.

After that the realization that you were a hair's breadth away from dead seeps in.

That's why I'm always droning on about electrical safety and telling people that if they don't already know how to do it safely, get someone who does have the experience to teach them. You can't write down the proper cautions in something that someone can read well enough to teach the precautions.

Again, sorry you got zapped - it is no fun at all.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

about a week ago i was working on a light in my house....

i turned off the switch, and was telling my wife how just because you
turn off a switch, doesnt mean that everything is safe.....( i.e.
turning off the breaker too.....)

then kablooeeee....i got zapped.  

total bummer man...

Yupp, there are no caution lights, you have to  :idea:  imagine your own.
 If you're not remembering the warnings, and following the recomendations thereof, you may not ever know you just got a reminder...the one that finished you.
 OH Yea, if you survive, {I survived a 100W plexi's big cap BAP!], you will remember it, [please consider yourself skilled [or smart enough to let the other guy stick his hand in there] to never recieve a jolt like that].
Convention creates following, following creates convention.

"Electrons. Can't live with 'em. Can't jam without 'em."

I'm going to have to remember that one!  :lol:

Electricity, power tools, flammables, firearms, and pets over 120lbs, will all kill you if you don't treat them with respect and common sense.

this is a good thread as a reminder to everyone to be cautious...

here are some good links:

you know what would be cool, would be to compile a list of
safety precautions when working on tube amps and such.....

also, share tips and devices that would aid in electronic safety....
i realize that we deal mostly with 9v.....stompboxes...but most
of us work on high voltage tube gear as well....it might just save
a life.....
