Re: Building a "reinforced" PS-503A

Dean, I understand that you will not help me in this one. I wish I had enough knowledge of electronics to design a circuit with similar features myself. Unfortunately it is not the case. So I have to resort to "reference designs", which I try to adapt to my particular needs. I used this circuit beca...

Building a "reinforced" PS-503A

Hi, last month I decided to build a new power supply for my bench. I have a Tektronix TM503 module and a PS-503A plugin, but I would like to have a "juicier" power supply, capable of outputing 3 to 4A. Since I have the schematics of the PS-503 and I am very happy with its features, I decided that my...

Semiconductor curve tracer for TEK TM50x module

Hello, I posted this topic some time ago and Dean Huster replied saying that he has modified a 5CT1N for that purpose and that he would send me some information soon. Well, time has passed, I have bought a 5CT1N and its operating manual, but I received no information. Then I am thinking in trying by...

Component video to S-VHS converter

Hi, I bought a DVD that has component video output but my TV has only S-VHS. Of course I could use the composite video input/output, but that would degrade signal quality. Does anyone knows a circuit that would combine the y Pb Pr signals to generate the Y/Cr signal? That would allow me to use the S...

Pulse Electronics plugins for Tektronix

Hi,
I have seen a couple of plugins made by this company recently in Ebay.
They seem to be designed for the TM-500 power modules, but I am not certain.
Also, I could not find any source for service/operation manuals for those units.
Any help?
Thank you

Re: curve tracer pugin for Tek TM-500

Dear Dean,
Yes, I am really serious about it, but I am still waiting for a 5CT1N to show up at Ebay.
Meanwhile I could buy a schematics of it and study your modifications, if you could send me a copy of what you have done.
Thank you a lot for always answering my questions.
Regards,
Rogerio

Fairchild 3817 clock IC and LCD

A friend gave me a large LCD display which I intend to use in an alarm clock.
This clock would be based on an Fairchild(!!) 3817 IC that I found in my junkbox.
However, I can not find any reference on how to use LCD displays with this IC (which is obsolete).
Any Ideas?

Tektronix TM500 rear connector

I am willing to make an extender cable for my TM-503 power module.
I bought a specially designed PCB that simulates the plug in side at Ebay, but I can not find the 0.156" spacing 28 position dual reading card connector, which will go on the other side.
Any suggestions?

Alarm clock with LCD display (non serial)

I came across a large LCD display which I thought would be nice in a digital alarm clock.
I checked the internet for a digital clock chip with the proper LCD drives, but to my surprise, I could not find ANY.
Any ideas?
