Nice schematic diagram, Gregg, but quite a complex circuit for use on a solid
state receiver

I have a simple one I built for my DX-392, using an LM317T, a pot for setting
the desired voltage, and the usual parts, including a center tapped 6.3 vac
transformer. I bought all of the parts, including the minibox, at Radio Shack.

I guess I'd better get busy and post my drawing as a web page. I first wanted
to refine it with notes so others could build it.

Do you heatsink the LM317T? I've been using a similar circuit
(substituting a wall wart for the transformer) as a battery charger
and the heatsink barely gets warm. I wonder if it'd be possible to
build a really compact unit without the heatsink, maybe even putting
it inside the wallwart package.

I'm specifically looking for one where there won't be a $15 shipping charge
on five dollars worth of parts.

As always/Thank you very much.

It's been several years but I have ordered from Digikey in the past, have
you looked at them??? If you find a good place for small oders let me know
(or post it) as I have several small projects I need to wrap up this winter.
I've ordered too many circuit boards from Far. Rob Mills ~

Do you heatsink the LM317T?

Yes, just out of practice. Too, everthing is mounted on and in an aluminum box.

I think there'd be too much too put inside a wall wart.

As for small amounts of small parts that were inquired about by another...

I've had great succes in ordering non-Shack stuff from All Electronics:

I have a mail order catalog of theirs, too. In it is listed a multi-volt/1-amp
wall wart, but it is a switching power supply, which would probably cause noise
on the bands.

Here's a few places I've done business with:

http://www.danssmallpartsandkits.net/

Dan has great prices and usually has a good turnaround time. I've been
100% satisfied. However, it's a one man operation, and there have been
times when he's been so backlogged that there have been newsgroup
threads wondering if Dan is still in business or even still alive.

Ocean State Electronics offers a huge stock of odd hobbyist/repair
items. Unfortunately, sometimes they are out of stock of the things
they offer. I also had one of my orders delayed for no known reason.
But, overall, they're not bad. They offer the stuff I wish Radio Shack
would have carried.

http://www.digikey.com/

Excellent service. Their web order page shows how many of a particular
item they have in stock. Very quick turnaround. $5 fee if the order is
under $25, if I recall.

Great for speakers. Some of their other parts such as electrolytics are
a pretty good deal. More excellent service.

One advantage (or disadvantage) of him is that he's focused on radio
related parts, and mainly long standard common items. So he's not
a good place to get the latest widget, and he is lacking in some things
that would be nice to order from him (such as a better selection of IF
filters), but for projects using common items you should be able to
get all the parts from him. You can get the semiconductors, the bypass
capacitors, the variable capacitors and the toroids. I'm not sure
a place like Digikey or Mouser carry toroids or variable capacitors (if
they do the latter, likely the prices would be high) so ordering elsewhere
might require multiple orders.
