Default Black Star Apollo 10

OK, you came up trumps with my last request for service info on a Levell audio osc. How about a Black Star Apollo 10 counter timer? There seem to be a few of these on sale just now, hopefully someone has some info please?
Thanks, John.

Should that be Apollo 100? Telford may help - http://www.telford-electronics.co.uk/manual.php?alpha=b

Black Star Apollo counter.
Could you post a photograph please. I have information upon several Black Star counters. None called Apollo, but that firm often seem to market under several different names.

There's a rough picture of the Apollo 10 on the first page of the attached pdf file, with a sketch of its front panel on the fifth page (numbered page 3).

Apollo counter.
The nearest I have is the Meteor counter. Uses the usual 7216 I.C. with a Plessey/GEC ECL divider for the higher frequency models.
This may give you a useful lead to the circuit. Your model may just have more elaborate switching.
So I attach the circuit. Let us know how well it compares with your actual machine.

Thank you Diabolical artificer, WME Bill & Hysteresis, for the information & links. I forgot to mention that I allready had the opperating instructions for the APOLLO series counter timers which all seem to have pages 7 & 8 missing. Looking at the Meteor series circuits is possible that the basic counter and display circuits are the same but as my instrument will not be ariving untill after the weekend I 'cant say yet. The complete dearth of any circuits for the Apollo series seems strange as the Meteor seem to have quite professionally produced circuits. The instrument I am having is supposed to be in full working order. But I have a "thing" about having circuits/manuals for all the test equipment I have.
WME Bill, when it arrives I will let you know how it compares.
Regards, John.

Hi John,

I've scanned my Apollo 10/100 Service Manual and put it in my Google Drive temporarily (~15MB):-

https://drive.google.com/file/d/1L6g...ew?usp=sharing

Since it doesn't appear to be available anywhere else I'll upload it to ElektroTanya later (when I've checked up how to...).

Cheers
Barry

Hi, Trigon, Thank you very much for downloading a copy of the service manual for the Apollo series counter timer. It was just what I was looking for.
