Some do that. If you want information on fixing it you'd need to give a whole heap more information than that. Since you haven't it seems unlikely you'd be able to do much more than check the mains plug.

It's official. Radio Shack is closing their doors. The nearest store to
me (in a big city about 60 miles away), is having a "going out of
business sale". Yesterday it was 80% off almost everything. But there
was little left to choose from. I got a few audio cables, some heat
shrink tubing and a couple 12v 1a transformers. That's about all I could
find.....
 
This is a sad day..... Radio Shack is the last of the old electronics
stores, and while they have not had much in recent years, I still liked
their stores, and over the years I found their equipment was made fairly
well.
 
The guy said they are presently going to keep about 70 stores, which is
about one per state, and they will only be in the very large cities.
 
This sucks!!!!

Radio Shack was NEVER an old time radio store.
Except maybe back in the '50s before Tandy Leather bought
them.
 
They sold predominately cheap import stuff.
Middle management was draconian at best. Always grinding
on the store managers to meet constantly changing quotas.
No amount of mismanagement or corporate greed could save
them.

So there was a bankruptcy even back then..... I did not know that, but
it seems they have gone thru a lot of them. Two recently.
 
I never understood the connection with the Tandy leather company. Maybe
there was no "real" connection, just that they bought the business. (Is
Tandy leather still around?).
 
There was a point when Radio Shack was called Allied Radio Shack. Did
Allied buy R.S. or was it the other way around? I dont know much about
the history, I only recall what I remember over the years. I remember
when they sold Archer brand items too.
 
However, I was pleased with most if not all of their gear, and I have
quite a bit of their stuff, from a few scanners, a radio, several
multimeters, lots of plugs and connectors, and a video switcher.
 
I realize their parts prices were on the high side, but I paid the price
because their stores were nearby and handy. Sure beats paying the
shipping from most places, and before the internet buying by mail was
involved, required mouth to mouth discussions and having a pile of paper
catalogs laying around. Far too complicated just to get a resistor,
capacitor, phono jack or semiconductor. It was easier to drive to R.S.
and just buy it. But I do agree their parts in recent years were very
skimpy and limited.
 
Regardless, I liked their stores and will miss them.....
 
The only reason I even found out that they were closing is because the
9volt battery connector broke on my portable weather radio, so I stopped
at R.S. to buy one. (I did not know they were closing). I had no problem
paying probably about $4 for one of them connectors. Now, I'm stuck
ordering one from ebay (I found a pack of 5 for about $3), but I hate
having to wait a week or more to get small parts like that, and my bench
piles up with projects waiting to be repaired, while I wait for parts.
Lately, when I buy a part, I usually buy 5 or more and keep them on
hand, so I have that stuff here. Its costing me more to stock all that
stuff in the end, but there is no way around it....
 
What once took a day or two to repair something sometimes takes months
now, because I have to keep waiting for each and every part I need.
Radio Shack provided a good service in that sense, and I was willing to
pay their prices for the convenience. Now they are gone, and I'm not
happy about it....

We still have these guys: http://store.acradiosupplyinc.com/
 
They may have a gussied up website, but they are still an 'old time' radio store with wooden floors, bins and hang-racks. And I can get a 'onesie' on a Saturday afternoon.
 
Not cheap. But, there.

Most of the components seemed to be low quality.
 
The manager of the local store 40 years ago had a major complaint with
the company. Whatever was on sale, the company would ship him many of
the items. He had an alotment of so many dollars. He may wind up with
half of that in antennas that he could not sell, but could not order
many of the items he could sell.
 
Even back in the 1970's I almost never bought anything from them in the
parts line. They did sell a few nice large items. Bought one of the
Model 3 TRS 80 computers from them, and a nice police scanner.

>The last one in my town closed about two weeks ago.
 
According to the guy at my local one, they are all closing or have
already closed in the last month. This one will be closed the last day
of this month. There is so little left that they may as well be closed
already but they are also selling shelves and parts of the store's that
are not attached to the walls of the building. I offerred to buy the
small parts drawers, but they were already sold and paid for. But he
said the buyer has to wait till May 31 to pick them up.
Some of the largfe shelves were already gone and there were 8 or 9 boxes
of cables and cords on the floor because they did not want to hang the
stuff again.
 
I asked if I could make an offer for an entire box of those cables, but
he told me to come back around the 29th or 30th. He said right now he
must still sell everything at the percentage off rate that corporate
told him to do. I may make a trip there on the 29th just to see if I can
get boxed deals.
 
I got a laugh, because I found a connector in the parts bin that was not
in a bag, and he said although all small parts were priced at $1 each,
he could not sell that plug without a part number, but since I spent
over $25, I could have it for free as a bonus. That was nice of him!

One part I seem to find that is more often than not, the correct size,
are those stereo 1/8th inch plugs that plug into a computer or MP3
player. They almost always seem to be a sloppy fit and get noisy because
of loose fitting.
 
I bought several cheap ones on ebay and they were all crappy (from
several sellers). I bought a Radio Shack one on Ebay for 3 times the
price of those cheap ones and it fit perfectly. The seller had 3 left. I
bought all of them, even at $6 a piece. I dont know why no one else can
make them things to fit properly, but I was happy to find some that did
fit and not annoy me with crappy sound.

Local store here is at 60% off.
Even at 60% off, they're still WAY more expensive than online.
RS was only viable if you had an emergency.

Yup, had a GREAT manager at the local RS -- helpful, knowledgeable, a
really nice guy. Sadly, they fired him because of the bogus quotas.

Back in the day, when we had Radio Shack in Canada, MOST of their
product was middle of the road or better. A lot of their stuff was
REALLy good stuff.

Here in Canada a LOT of the stores were franchises - locally owned
businesses that HQ could not fire - - -

They're long gone in central Virginia.
 
There is nowhere else to get a connector or other small part locally. Big box home improvement stores don't have anything close, and the specialty hardware stores were driven out of business long ago.
 
Yeah, you can get cheaper and better stuff online, but you can't have it when you need it.

does the protection circuit sense the current i.e. voltage drop across the emitter ballast resistors?
 
have they changed value?
 
is the quiescent current correct?

the RCA cables you get on Ebay these days, the ground tabs are so thin that they don't hold tight at all when you plug them in.
 
I've taken to soldering wires around them which is a colossal waste of my time.
I'd rather pay a little more for a usable connector. Like they were 5 years ago.
 
Anybody know a source of not audiophool cables but just decent usable RCA cables.

Take a look through the selection of RCA audio cables available at
Markertek. They have a whole range of types and prices.
 
The ones made by Sescom, using Mogami Neglex cable and "the highest
quality connectors from Neutrik, Connectronics & Switchcraft" might be
a reasonable tradeoff between quality and price.
 
Another option would be to rip the RCA jacks out of your equipment and
install BNC. The cables aren't necessarily cheaper than RCA, but it's
a better-designed connector.

It would take me a month or two to replace all the RCA connectors in my
stuff..... Heck, some of the stuff has about 25 of them on ONE piece of
gear.
