sorry i can't help.

I have just joined your group and reading through the posts show you have a lot of knowledgeable and helpfull folks here. I don't want to be a brain picker, but are newbie's allowed to start with a

I'm trying to locate a CRT to repair my Sony/Tek scope. The Part No. is 154-0866-00. I'm willing to pay a reasonable price for one. I would also consider purchasing a dead or near dead 336 scope to

I need a Fixed film resistor for a TEK 464 scope. Part no 307-0431-01 Thanks in advance Rob

Hi Rick, I might have some of the caps you need but I will need Tek Part Numbers to do a good search of my stock. Stan w7ni@... Rick Davis wrote:

Anyone have or know where I might be able to get one or both frame adapters to adapt to my C30 camera: A 016-0269-02 for a TEK 475A to C30 and/or a 016-0248-00 for 7000 series to C30. Thanks in

Hi, I just bought a 7704A which works, but poorly. It only has a bandwidth of 170MHz and the tube blooms badly at a low intensity. It looks like it needs a new tube but does anyone know whether a

Looking for a source for the Sprague 68D series caps used on the rectifier board of the 7633. Apparently Mallory made a cross at one time. I need the 9600uf for sure. I suspect there will be others

Hi All, What will be the replacement part for 151-0487-00 ( a transistor) from the power supply of Tek scope 7603? Many thanks. Regards, feng

Digikey has a limited number of HV caps. You can always make series/parallel combinations too... You'd probably want equalizing resistors in the case of series strings. p.s., I've probably

My Tek model 570 vacuum tube curve tracer seems to have lost the ability to keep the high voltage running. When it is first powered on, I get a nice trace, but the HV oscillator tube (6AQ5) looks

I am looking for the 'lock down assembly' for a TEK MOD-3 scope mobile cart. I am using a TEK R217 rack cart and would like to mount a lock down for my 7904. Anyone have a spare or any idea where I

I was going to suggest that maybe, with questions like that, you could use a copy of my book (OSCILLOSCOPES--Selecting and Restoring a Classic) that is full of such descriptions and includes both the

1A5 is an amplifier with differential inputs and up to 50 Mhz bandpass, depending on sensitivity. It has an input for a special differential probe P6046 and also has a comparison power supply

Does anyone know the difference between the 1A5 and 1A7 differential plug ins? thx ----------------------------------------------------------------- Michael Dunn | Surround Sound Decoder &

Strip off any easily strippable parts, hardware, knobs, etc, and sell grab bags of Tek parts. Tempting :-) Could you post a rough list of 7000 modules...? Any particularly "interesting"
