In this case the "assembler" needed flogging!

This was a very interesting post Henry, I have one of these and it seems to
be working OK. I have everything except the cal cell is dead. I would like to see a pic of those jam nuts that you shouldn't touch if possible as I thought about cleaning the card reader.

Hi,
The calibration cell simply verifies that the meter is 100 microamps and a total of 250 ohms. And it contains the limit resistors for the leakage test. I wouldn't worry about it. Incidentally I wouldn't use any silicone lubricants on the card-reader pins. While the original organic grease has stiffened with time and needed to be replaced, it was probably carefully selected to do its job. On the Cardmatics I've repaired, I've used a grease originally supplied to General Radio by Oak, but I have no idea where to get more of it. It was described to me by the GR engineer who gave me some, as "Beacon M325" grease. 73, Alan |

For noisy TV tuners back in the 1960s when I was working in a Radio and TV
shop we used Lubriplate white grease that came in a small black and grey tube that resembled travel toothpaste.We sprayed the wafer switch in the tuner, rotated several times and then applied a light coating of Lubrplate with a small stick and rotated several more times. On turret tuners we cleaned the pads and wipers with contact cleaner on a Qtip and then applied Lubriplate. This was in Norman, Okla where the humidity played havoc with tuners making them intermittent and after the treatment we never had call backs. Somewhere I have a partial tube of this stuff but haven't located it as yet, so I used DeOxit on the Hickok switch matirix but would have used Lubriplate if I found it. After about more than 20 moves there's lots of possiblities where it is. Two local auto parts stores didn't have anything but silicone grease which I haven't used except as a heat transfer aid on power transistor heart sinks. I think that Lubriplate would be a good lubricant/protector unless there's something better that I don't know about. I'm guessing that there's something better after 40 yeats and would be interested in what users have used Now to repair number 2! 73 hank wd5jfr "Alan Douglas" adouglasatgis.net wrote in message ...

Very nice going, but I'm not able to see your photos (server doesn't have that newsgroup) so could you describe for the rest of us what this connection looked like? thanks, - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
