My second question is what do you guys think about Acopian power supplies? I

Hi all,
Can anybody lead me to information on the Tracor 895A Linear Phase / Time
Comparator? A simple google search doesn't turn up much.

for Tracor 895 at $20. I just got a Montronics Freq Diff meter manual from
them.

Hi, I dont know about other counties but the oad shedding is certainly still
dont this way in the UK, BUT the incremental frequency adjectments are
corrected for the mean daily frequency to be correvt at 06:00 in the

time!!

Hi all,
I also have a Tracor 895 and have a copy of the manual. It is all discrete
stuff , no IC's.
If you reqire a copy, that should be no problem.

Hi Tom:
Nice overview.
Charles and Ray Eames did:
Powers of Ten http://www.imdb.com/title/tt0078106/
Toccata for Toy Trains http://www.imdb.com/title/tt0051091/
and the Eames chair which is still available from Herman Miller:
Thanks I'll give that a try.

How can it have (as a clock)?
