Please send me the list of plug-ins. I repair them as a hobby. grbosworth@... Gary wrote: -- Gary Robert Bosworth grbosworth@... Tel: 310-317-2247

Does anyone know the generic part number and manufacturer for the Tektronix part number 151-0405-00? It is an NPN Silicon darlington transistor in a TO-126 package. It is used in the power supply of

Hello, I looked at these.  It looks like all are SD, not USB.  I also need a 26 pin interface.  HXC did have one USB emulator with a 26 pin interface but it is USB type B.  Not quite what I

Well, Dennis, in that case, I'm in the same boat as you; I already have enough stuff in my garage lab in need of repair.  And not enough time to do so.Hopefully some retired folks with more time on

Have a look at http://hxc2001.free.fr/floppy_drive_emulator/ HXC may already have one or , from experience, seem happy to program one for you.

I have quite a few 7000 plugins in need of repair and I don't have the time to do it. I have two goals in mind: 1) be sure each plugin goes where it will do the most good; 2) Learn how to become a

I remember enjoying your story a couple weeks ago about you meeting him. Oddly enough later that day after reading your story I was out shopping with my girlfriend who just so happened to purchase the

If the little AC/DC/GND switch can handle the voltage. Tektronix was silent on the issue, which usually means you have to hope you are lucky. -Chuck Harris John Williams wrote:

Thanks John. Is there a chance that even though that capacitor was spec'd at 600 volts there may be a possibility that other components in the circuit aren't - that they tossed in the 600 VDC rated

From Tim P (UK) I have a manual, thanks - in fact, after perusing the schematic, I realised that my +38 V on the +30V test point is the UNREG voltage. So, maybe the erstwhile +30V is not being

Jamie the input capacitor is specd at 600 vdc. That means that the input dc plus peak ac should not exceed 600.

Tim, TekWiki has a complete 5441 manual. http://w140.com/tekwiki/wiki/5441 It doesn't have "voltage and waveform" data but has the schematic, board layout, adjustment & Theory of Operation info. Do

Of course I've nev<cough>r put a cap in backwards... I don't have a 51xx scope, but I looked at a bunch of 51xx manuals & schematics in the course of figuring out 5D10/mainframe interaction

The advantage of 100X probes P6007 and P6009 is that the divider is (mostly) inside the probe. Then the input capacitor sees not a high voltage. Albert

Thanks Nenad. This gives me some things to think about. I also do have a 1A1 plugin so I may go with that. It is rated for 600V but to your point due to the age I'm really pushing things to the max. I

( I sent this some time ago but I think I only sent it to myself, I'll try again) When I was servicing TV's (mid 60's!) we carried, in our tube caddy, tiny auto-transformers that would, for most BW

I finally found the time to check the DAC sample-and-hold circuits for the Intensity signals, and they tested perfectly fine. Both the readout and display levels (ROIR and DIR) at the output of the op

Hello All, Can someone tell me which USB floppy emulator will fit and function in the TDS3000B scopes? I found some on ebay that say they are for the TDS3000 but they are a bit pricey. Tom

OK, I must confess I had the replacement cap in backwards. A new cap with the correct polarity fixed the -30V problem. I still would like some tips on how to troubleshoot the 5110 scope. The

I have (painstakingly) gone through my non-Beaverton Tek gear and the serial-numbers and here is the
