Hi Peeps....... Just on the whim.... I bought a Promax Satellite meter from ebay..only 20£ ish...... as a donor more than anything...
Problem is there are two devices I cannot find a data sheet for..
See attached photo's
The TFK . is it 929 or 626 ?? as the 2 is printed upside down.... I tried both numbers... to no result.

The TSC911 also seems to be untraceable ...

I am sure someone out there has info... yes they will be obsolete...and not obtainable, but I like my database to be as complete as possible.... If I dont have data the will be binned

Hi
I think that the TFK device may be TFK6060B which does exist but no data to hand unfortunately

TSC 911 is a Teledyne auto-zeroed op. amp. Perhaps someone has a mid '80s data book?

U6060B, TFK is only the brand name and not part of the type number.

Here's the TSC 911 datasheet (the U6060b is a bog standard for the time 1GHz prescaler)
