Be cheaper to build an Axis Face

The thing was $185.00 new, I tried to sell on eBay a while back for $150.00, but it didn't sell. It's not the NKT version either, I paid for the regular SF, but was sent an NKT version, & sent it back cause it sounded grainy to me. So this is the NKT version(w/trimpot for bias), but with 2N508 Ge(General Electric) trannys with the original boxes the transistors came in also. I've got the bag, box, and manual also. If you've got a Marshall Plexi or an old tube amp of some sort, this thing will light it up. It would be cheaper to build Phillip's version, but PM if interested.

Hmm 2N508 you say?  I'll have to source some of those and plug em in!  Hopefully soon some will pop up on eBay.

I think Mike has them all! I never see them anywhere, but good luck!

I think you're right!  Ebay sure didn't turn up anything.  I did a Yahoo search and some of the old electronics surplus houses have some for sell, but their prices are usually VERY steep...sometimes up to $5 or more for a single transistor.  I got my 2N404s off eBay for about 80 cents each when I bought a bag of 10 NOS Texas Instruments pieces.  

I think I'll keep grabbing all the 2N404s that I get get ahold of for now  I still want to try out some 2N404A.

I looked too, nothing. While we're on the Ge subject, anybody try the AC128/01 heatsink transistors. Are they pretty much the same as the standard 128's, gain and character wise? Any more consistant? At first glance, you'd think they'd hold up better when the temp goes up, but who knows?

Here's a page that gives some detail on different types of the AC128, including those AC128/01 that the eBay seller has been auctioning recently:

I've been eyeballing those auctions, but I've never bid on them...I wish that he would put some up as "buy it now"...waiting 6 or 7 days annoys me like nothing else...but I've always been impatient

Phillip

Thanks, for some reason, I was under the impression that they were higher gain. I know what you mean about those auctions. Waiting all that time is like watching water boil. :x  Just once, I'd like to be the guy that finds a whole case of them in a corner of some warehouse.

I got a couple of those modern reproductions of the AC128...they suck.  These days they're also remarking/restamping various no name Germanium transistors as NKT275s and selling them on eBay as "Genuine NOS" NKT275.  I'd say that over 90% of the "NKT275s" that have sold on eBay are restamps or reproductions because the real ones are so hard to get.

Those are definitely real AC128/01s, though.  As far as I know, no one has gone to the trouble of trying to fake the ones with heat sinks.

Phillip

What do the modern repro 128's look like? Are they the metal cased, top hat style? How are they usually marked?

The repro AC128s look like the one pictured under #3 on that AC128 page.  The originals didn't have the little flange around the bottom of the case.  They looked like the NKTs and lots of other part numbers.
