supply for old audio transistors (driver transistors: 2SD381 / 2SB536)

Hi,
I find it pretty hard to find a shop that actually understands what
one is asking for... I my case most of the shops I called up they did
not even know the amplification class of their transistors in stock
(not to mention the voltage selection I need, or anything about
matched pairs).
So my question is - does anyone know a good shop that has the above
transistors with a K or L amplification factor (hfe around 80-160) and
a Vceo selection of 180V (2 or Z) and is located / ships to the US?
If this seems hard to come by - I found the following (possible)
substitions that are probably equally hard to get (plus, I have no
data at all regarding these transistors):
2SB536 -- 2SA1011, 2SB1085, 2SA814, 2SA1078, 2SB1414
2SD381 -- 2SC2344, 2SD1592, 2SC1624, 2SD1138, 2SD1562
Are there more recent types available that could be used and are
easier to find?
Thanks,
AlKlecks.

Did you try Digikey? NTE has a line of replacement transistors too but you will need a real electronic shop, not Radio Shack. A quick peek at the NTE crossref shows 2SB536 is a NTE292 SA1011 is a NTE398 etc
Email me and I will send you the NTE crossref program, but it's an old copy (95 or so?)

Nevermind ... just go here (The NTE site)

They have that search online now along with datasheets of the hits.

news:sci.electronics.repair would be a better place to look for help. Check out Sam's RepairFAQ for a list of vendors who sell repair parts for newer equipment.
Industry Number : 2SB536M NTE Device Number: NTE292 T-PNP,SI-POWER OUTPUT/SW,TO-220

And what's really great about NTE is that you can download a database with all that info on it.. :)

A good vendor I have used for Japanese parts in Consolidated Electronics. I think their # is 800-543-3568 or ceitron.com. They have been in biz since I was a kid repairing 8-tracks, and also sell NTE's.

If you live near a well-stocked Fry's, you'll find a rack with gazillions of NTE parts on it. Nice.

Is there such a thing as a well-stocked Fry's? There are two Fry's in metro Phoenix, and I have spent hours, literally, staring at empty racks and Temporarily Out of Stock tags.

Don't know. The one near me opened just two months ago, and it's stocked coming out the keister.
Personally, I don't find staring at empty racks for extended periods to be very entertaining. But, chacun a son gout.

Bill, More than once I have complained to the parts area manager. Result, Same old out of stock condition. My guess is that Ill have to talk to someone in the upper end of sales and explain about how getting folks who like to fix things in the store, sells other stuff also. A happy customer comes back. If it wasn't for the very low sale prices they have (read rebates), I wouldn't even go into that mess of a store. The check out line is the largest pile of BS I've ever seen.
Bob in phx (who now feels better after venting) p.s. I was spoiled by Tech America when they were here. Nice stock and good guys behind the counter. I never found them out of stock on anything. To bad the rest of the store sucked...

Bill, You might try circuit specialist in Mesa. They are pretty well stocked, but don't expect any low prices.

After wandering through the Fry's that opened here in San Marcos last June, what impressed me most was how many parts they carry that are useful for repairing old radios. I found good-sounding 4-ohm speakers (4", 5", 6"), 450-volt electrolytics, all kinds of film caps, power resistors, 3AG fuses, RF inductors and toroids, 70.7-volt line transformers (good for matching 500- or 5000-ohm boatanchors to 4- or 8-ohm speakers), bulbs (#44, #47, and dozens more), contact cleaner, all kinds of soldering stuff, test equipment including Tektronix scopes, and other things I've forgot. They even have some Philmore parts--I don't recall seeing that name on a parts rack since the 1960s. It's been a long time since I've found this kind of stuff stocked nearby.

As I said to the Fry brothers on opening day... "No more Radio Shack."

Thanks for the tip, Bob. I don't mind paying. I DO MIND driving 50 miles round trip, killing half a day, and finding only half of the parts on my list - thus accomplishing exactly nothing toward my project.
Seems to me the Fry's in Silicon Valley weren't much better.

There aren't any down here either. Thousand oaks, Coste Mesa, Burbank, Manhattan Beach....
All have either gaping holes in the stock, or what they do have, has the dreaded "A Fry's Sales Associate has checked the contents." tag of death.

Thanks Steve,
they even had the power transistors I didn't dare to ask (2SA909, 2SC1486). So I ordered from them.
Just a remark, I do have the NTE software (

) and was finding the "matches" but the NTE types are not really the same. As for Fry's, only if I'm really desperate and willing to pay extra I go and check out whats available there... Standard stuff (R's, C's) they are pretty well stocked here in Austin, but nothing exotic.
Thx,
AlKlecks.
