I'll order one and give it a try. Bob.

I use one of these and love it for close work: Carson Optical Pro Series MagniVisor Deluxe Head-Worn LED Lighted Magnifier with 4 Different Lenses (1.5x, 2x, 2.5x, 3x)

Just a quick word of caution. The A5 board is a multi-layer board and there are interlayer conductors to the pins of the NVRAM. You really want to use good desoldering equipment and techniques when

I have a scope that fails 04 my need calibration and can't I find the 2445B NVRAM in files section can someone point me in the correct direction? Joe

I need the nameplate above the crt on the front panel. Anybody have one laying around? Thanks! Marty KL7AM

What do you like most in you 2468B (vs 9374L)? I am interesting because i use (and have) many analog and digital oscilloscopes, and 9354L was the fist DSO i liked, mostly because great

Hi, Also have anyone transferred the 2445B NVRAM content into the 2445A SRAM? There is a 2445B NVRAM file kindly uploaded by Mitchell Kobierowski in this forum. Technically it's possible to upload

Hello, I'm still struggling with 2445A calibration. Good news - I have completely repaired and calibrated TG501. Bad news - I don't have neither the tunnel diode pulser nor the PG506 and I don't

I have a couple pair of the cheap loupes. The 3.5X are pretty handy for general work and I use them quite a bit. I also have a higher power set but those are not very good since they shake with my

Robin, This may sound gross but I have a near mint 7704A that I bought for less than the value of the 7T11 sampling timebase that came with it. Since it is the only one of my 7000 frames that splits

IIRC the 468 ROM's came in three revisions, -00, -01 & -02, where -00 and -01 were Mostek. The -02 had the same digital content as the -01 but were CY7C264 EPROM's. The Mostek's are unreliable and for

Hi Roger, A 7603 would be lovely. I have a working ish but in needs attention 7704A with plugins that I’d happily swap for it. I need the space but don’t want to skip anything unless I can

Dear Menahem, Sergey, Harvey, Chuck and others, thanks for your advice, I did end up buying it as a refurb seems within my ability. Fortunately I do have a desolder station and can replace the chip

Dave - my continued and grateful thanks for the hard work in scanning these unique documents. They are a superb resource for us in restoring and repairing our Tek gear. Craig

This may need a special USB 'Y' power cable to get enough current to operate. I had to buy them for some external hard drives, and a DVD burner.

Based on requests we have scanned the 151- transistors and it is now on tekwiki.org. It is 762 pages. We have been asked about OCRing the document. That would make it searchable but the experiments

Probably the same as the stuff used to tie old electric motor windings. I think it's just called "lacing cord" and there are a few different varieties. Some are heat shrinkable. I have a spool here

I'm tossing around the thought of restoring a 468. It has Mostek MK36694J-5 and MK36693J-5 ROMs. Are these something that in order to do a proper restore need to be replaced? I had originally planned

I think they might be good. They have a clear part that is big like safety glasses, so maybe you can fit your prescription lenses in a frame under them.
