Just wanted to contribute to this compilation of long-gone electronics surplus dealers. From the late 1960s through the early '80s, I knew of three such stores in the northern Virginia suburbs of

I just stumbled across this about BNC repair: https://patents.google.com/patent/US4416143 Ed

Tek had a very strong "do it ourselves" attitude. Since they had to make many jigs and tools they made many of the tools even one could buy them I use to have a small collection of parts used to make

Lorn... Ah, in time... about your writing: Since between pins 2,3 and pin 1 there's only the base-emitter junction of the IC's input transistor... if the input is at 0,7V or so, it's expected that

A quick search found this in a few

Dennis guesswith the pictures is correct. It was made by Tek. Tek had (when I was there) part of it's model shop a tool modification and manufacturing department. There was at one time a catalog of

hi Lorn, On your previous writing: Look carefully... it's more likely it's socketed than not. Tek used a lot a kind of socket that is made of individual socket pins that go directly on the board...

Hi Larry, I just uploaded some pictures of the tool. They are at /g/TekScopes/album?id=45980 Dennis Tillman W7PF

If I'm not mistaken, 1/2" 6061-T6 aluminum tubing with two slots cut in it 180-degrees apart would do just about as nicely as anything for that. Thanks, Barry - N4BUQ

Yes, that BNC T-wrench on ebay is yet another form of installer. I have two different kinds from long ago, both commercial tools, but I have no ID or source info. One is made just like a nut driver,

Hi Peter, Besides the check to the power supply's capacitors, as Chuck noted and, as you will notice follwoing up the threads, is a kind of "standard" advice for all equipment of this vintage... It

Ok, cool. So I need to isolate whether the input transistors are leaky or whether there's a problem with the chip. The transistors are socketed but the chip is not. So it's not practical to casually

Someone here mentioned a BNC installation tool. I took that in context to mean a tool that holds a chassis-mount female BNC jack while tightening the backside nut but I don't find any such tool when

Hello Lorn, I also own a 464 and mine also had a problem triggering... And while looking at your description I looks like deja vu to me. On mine one of the FET transistors of the input circuitry were

Hello Vaclav. This forum doesn't take attachments...It's sort of controversial, but bottom line is that it doesn't. You need to post the pictures to the photos section and... since there's no way to

I would appreciate some assistance to find out why my 464 has this problem. I do have a shop manual. PS this is? my first post here so please no flames if I did it wrong. Vaclav in Houston TX

I have two 465s. I have repaired one. They way it is constructed does not lend itself to be easily repaired. One must be patient with repairs on a 465. Also be very careful about moving boards around.
