VIBROGRAF M 700 LED SCALE

[JerseyMo]

anyone have instrctions oh how to use  a VIBROGRAF M 700 LED SCALE?

[AndyHull]

Not much available online. That image may or may not be of some use to you. Have you just bought one?

[JerseyMo]

I was given one to sell on comission.  Can't get much to happend on the device other thatn to see the power lights come one.  I think the mic is bad.  Oh well this will be a sold as is......or also useful as a very large paper weight or door stop

[JerseyMo]

well, given my curisolity and the fact that I was once a "pinball wizard" I had to have a look inside this device.  Sure enough just as I thought there was a chance that something on the power supply was not quite right.  This volatge regulator was broken off the board. UA78M12HC F7911 - 12V bipolar 3 pin.   $14.00 on ebay   will do some voltage testing before I order it.  So about the "pnball wizard" - long story short is I was the lead technican for an amusment company for 10 years.  1980 - 1990.  It was an assistent directory at Columbia University that gave me the nickname of "JerseyMo".

this post is kinda old, but maybe the guy offering the manual is still active.

thanks, its been quite sometime since I login in there but will check it out.  For now I have removed the broken leads and ordered the regulator.  for the cost its is worth a shot....

[JerseyMo]

well I got it to light up some more after replacing the 12v regulator.  Make sense since the 12 v runs the audio.

any way  Not sure just how it works but if I unplug the mic the leds do shut off.

Interesting. Do you have any better images of the boards that show the IC part numbers?

Is that device  heatsinked on the case next to the power board another regulator or a power transistor?

Any date codes on those chips?

Is it a mix of analog and digital or all analog?

What does that long steel roller at the front do?

no more pics, as I have put this back together and will listings it fr sale  "AS IS".

yes, that is another regulator and I'd say it was the 5v.  

did not look for date codes.  all digital that roller is just part of the display assembly.  

Was a fun porject and I was happy with the result and even more that I was able to remember the bascis of the electronics related to the power supply.

Sorry Guys, 

I am  located in Germany.  Enjoy Measurement instruments related to  Time and Frequency Systems and have dabbled with the usual timers, hence keen to keep in touch with this topic. Not a watch Tech myself but more into electronics for daily bread.

Just joined up, & received the  email abt Forum rules. no reference to any commercial activity. How may I contact you  Jersey Mo. I believe a personal link for contact is allowed.

Nice to be here.

More pictures of inside.   I just now notice all of the ITT components. They had a huge facility on route 3 East, a few miles from where I now work.  The location has recenlty been converted to a shopping mall.

Is yours faulty?

[JayMcleran]

Did any of you guys ever find a manual for one of these. I just purchased one myself and would be willing to pay for a copy of a manual if someone has one.

 

Thanks Jay

I  have a manual for the Vibrograph MU700 if some one is still  looking.  I don’t know if it is acceptable  on this site to respond.

It would be acceptable if it was a PDF and preferably not a super huge file size. Just on the rare cases somebody actually makes it here to find the discussion.
