There's a posting from yesterday.. 'For sale Radio Receiver and

no complaints in that thread..

A quick google search shows 1270 hits for 'for sale' in
sci.electronics.misc

So, ignore the last paragraph.. have you had any experience selling
used equipment to dealers?.. Thou, as I stated, I'd rather get this
stuff to an electronics enthusiast vs. a reseller company if the price
ended up being the same..

Well, not directly, unless there's another coiler in the immediate
area. That's partly why I recommended the OP read the archives first,
because of all the !!!SAFETY!!! !!!WARNINGS!!! you have to wade through
first. OTOH if the OP has done any hands-on with a mere model-T coil,
he's prolly had a couple mild zaps. Now that I think of it, surviving
those could make one overconfident...

I'm still having problems with maintaining oscillation. But every

Chuck Harris said something like, "get it oscillating at a normal

frequency first, then fine-tune it" - at first, I thought, "Well, yeah, if
you divide all the caps by, say, 100 - but would that mess with the
impedances?" And the part with the brains said, "No, the impedances will
be the same, but at the higher frequency".

At least you'd be able to see it go through a cycle or two before the

Good Luck!

I have a device that comes with an AC adaptor, with the following description
(whatever it all means):
AC ADAPTOR
CORD CONNECTED CLASS 2 POWER UNITS
MODEL: TEAD-57-122000U
INPUT: 120VAC 60Hz 36W
OUTPUT: 12VDC 2A
UL LISTED 4G38 E159614(T)

Then some diagram and MADE IN CHINA.

To me, it looks like a perfectly ordinary 2-prong adaptor. The instructions
for the device that uses it (a shop machine with motors that run off the
adaptor) say that it is important to ground it and that one needs to purchase
a 3-prong adaptor and shows pictures of how it fits into a 3-prong wall socket.

I've done that in the past when I've connected stuff directly to wall sockets.
There is usually a screw or something that one can use to connect a lead
coming out of the 3-prong adaptor. However, at the moment, I want to
plug it into a power strip and there is nothing to connect the lead
wire to. So I'm not sure what to do.

Normally I wouldn't worry about it. I would just plug the 2 prong adaptor
into the power strip and forget about the third hold. But I'm trying to
do this as carefully as possible, including confronting possibly unnecessary
details that might turn out to matter. So, with apologies in advance for
what is undoubtedly the dumbest question of the new year so far, can someone
please explain how to make sure the thing is properly grounded under these
circumstances?
just use a water pipe, screw on the outlet box etc and connect it

directly to the metal case of the equipment.

Probably because at least it's blatant and up-front.
You seem to be trying to do the same thing (sell something) but are
pretending that you're not.

Never said I wasn't selling anything.. I'm sorry if you got the
impression that I was attempting to sell all my stuff in s.e.m. That's
not my intent.. I'd rather get rid of everything in one shot, but I did
mention that there was a 'one liner' at the end for any individuals
interested.

My intent was to find if anyone had personal experience dealing with
equipment resellers..

A quick google search shows 1270 hits for 'for sale' in
sci.electronics.misc

---
1270 wrong doesn't make yours any less wrong.
---

No mention of any wrongdoing in any of the 4 or so FS, FA posts just
in the past two weeks could possibly indicate to a reasonable
individual that posting 'for sale' is ok.. I'm not going to go through
each of the 1270 posts that the search returned to see if anyone
objected to any of those..

Perhaps if I was 'blatant and up front' it'd be ok?

So, ignore the last paragraph..

---
A little late for that, don't you think?

Nah, it's never too late.. not until you die. For starters, someone
could start mentioning to people doing FS/FA posts that this isn't the
place for it..

http://groups-beta.google.com/group/sci.electronics.design/browse_frm/thread/4725d59ca9005733/baaa070f2b33a732?q=guide+to+the+sci.electronics&_done=%2Fgroup%2Fsci.electronics.misc%2Fsearch%3Fq%3Dguide+to+the+sci.electronics%26start%3D0%26&_doneTitle=Back+to+Search&&d#baaa070f2b33a732

Don't know if the link came through, but also mentioning a search for
'guide for the sci.electronics' post by Mark Zenier (dated January 21,
1999) might offer some insight to what the various sci.electronics
groups are for..

"sci.electronics.misc General discussions of the field of
electronics.

"General discussions on the topic of electronics. (Discussions
on the relative merits of various consumer electronics
equipment
are better held in the groups in the rec hierarchy devoted to
those topics.)"

... that industry equipment for sale posts would be better suited for
misc.industry.electronics.marketplace
I appreciate the understanding and help..

Jim, it's rather basic ... the forums are for all kinds of purposes but not
for selling items, unless they are specifically identified for that purpose.
Please understand that folks don't want to see ads unless they want to buy.
Why don't you investigate reasonable venues and not waste your time here?

More like sitting through four years of PhDs spouting political advocacy

so you can get a certificate and make the big bucks.

If you can sit there and train your brain to receive Morse Code, you're
worthy of the epithet, "Radio Amateur".
