I am interested in a copy too. Thank you. Gerhard

Let me try to find it! Ah, found, here you have: http://www.4shared.com/office/fDjyCD9K/Tek_AX-3557_TM500_Module_Teste.html Hope it is useful to you :)

Alexandre, I would be interested in having a copy of that schematic. Would it be possible to post a copy? Cheers, DaveD

USPS Flat Rate has a 20 lb max shipping weight for international. 73 Jim N6OTQ

Hi there Dave! I believe you CANNOT PLUG ANYTING into a TM-50x mainframe before checking it. BTW, I think I can create a small tool that you plug in each slot and tests everything (transistors,

I may be miss-understanding something but flat rate allows 70lbs so minimize the volume and put it in the smallest USPS flat rate box that it will fit in. If it won't fit in a large flat rate then

Hello everyone: Been long over due so, First lest me say what a awesome group this is, a several members have really helped me out a lot over the years. I have been able to help several members

If you could possibly divide it into 2 pieces, both under 20 pounds, the cheapest way would be 2 USPS flat rate boxes. Otherwise plain USPS.

OK, glad to hear that! Raymond

USPS, with you own packaging. but it will take about 4 weeks to 6 weeks to arrive !

Hello group What is the cheapest way to ship a 35 pound block of steel (not literally but just to convey density and robustness) from CA to the Chek Republic)? Eric

I purchased original NOS Tektronix p/n tunnel diodes listed in the 475 manual.

Hi, A pix of the 7x03 prototype as a min load in my A7704 acquisition unit. seems happy. Jerry Massengale

It sure looks like it is. Does anyone with an original Tek 7K extender confirm that the wires in the custom ribbon cable were 24 gauge except for the coaxes? Thanks, John

Well for 100 W into 50 Ohms you will have 70.7V rms or 100 V peak.? If the 'scope can handle that, you don't need an attenuator.? If it can't, you can cobble an attenuator from a pair of resistors

Also make sure that the 2 boards, A2100 DVM analog board and A2000, DVM logic & readout board are only connected/touching where they should. There needs to be a small space (say 1mm or less) between

You don't want the scope attenuator to be the dummy load. You can make a simple pick-off tee with the main signal going straight through, with a high resistance tapped off, feeding a termination

About ten years ago I built a dummy?load out of some huge 850 ohm?power resistors I?picked up at a hamfest. I?mounted a pair of heavy copper wires like a pair of rails?and then soldered the

That is because most sellers think they are just wires and are scrapped.

I know what you mean. Those tiny connectors are a PITA. When I first got a 7D01, I searched a lot for the probes, and considered even hard wiring some kind of cables into the front-end to go to
