I have 2 Triplett meters, a modern telecom one model a telecom specific Local Loop Tester Model 4, and a really old one, a 666R. That high voltage the model 4 has is used to apply 45-47 volts to a

I have two 475s that I acquired about ten years ago, and still going strong. I've never even opened them up. Ed

Ting, With all the component replacement I did on the secondary sided rails, I was not too concerned with the P-P. I did measure and record them both before and after replacement, but I did't know

Interesting. My new variant will have a external input and a internal RC schmitt trigger relaxation oscillator. The external inputs will be unterminated, 50ohm to ground, 120/82 ohms to Vcc/Gnd for

Another old 475 with original caps, eh? Maybe the design is particularly robust, or they got a really good batch of caps that year! ;-)

I too have a variant of the NC7SZ14 fast edge generator. Mine follows a 28MHz DIP crystal oscillator so the rep rate is fast enough to use with a7T11. It is air wired with SMD components directly on

Since the focus of interest is line noise ripple, I used the bandwidth limit switch and HF reject triggering to damp out most HF stuff. Using the Line as trigger source should also help.

Ed, Congratulations The 7J20 is indeed as rare as hen's teeth. Fewer than 100 were made, and more likely it was only 50. It is a real oddball plugin of interest to a very select group of chemists or

Hi David, Thank you for your reply. As I said before the problem is in the partly connected Q3005 Transistor. TM5003's and TM5006(A)'s have the same Transistor, but differently connected. On this

There are several screws & standoffs that allow you to disassemble the sandwiched boards. They are visible from the left side. You need to remove the knobs and separate the faceplate first so you can

Hey! ?I claimed "dibs" on that one if one should come up in the spring cleaning! ? I have thus already licked that chocolate chip cookie! The one from Craigslist sounds like it could be it. ?At

Curiously I never found it to be as bad as people claimed. I tend to fall asleep in the dentists chair and only wake up if they want me to do something. I think being an engineer helps, since if

Yes, I need the 7J20, can you ship to Spain :) I will pay shipping costs of course. Regards Mmiguel De: TekScopes@... [mailto:TekScopes@...] Enviado el: viernes, 1

I was just looking back through old posts here, and noticed someone had mentioned a 7J20(?). I never heard of this one, but recall that I stumbled upon a craigslist ad about a week ago while looking

Well it seems not. But anyway I found what I needed (I think); under Manage My Groups it is possible to change email address even though My Accounts does NOT permit a change (I've just confirmed that
