Title: Help locating service manual
Post by: dENc58 on May 07, 2020, 03:38:37 am

Hi to all
I am new to the forum and I need some help
I have pulled out an old oscilloscope from storage and want to repair it, but I need a service manual or at least a schematic for it
it is made by Soar Corporation, model number is MS-6020
I managed to find an operating manual for a similar series of scopes but no sevice info
The scope is functional but needs some work
Can anybody help

the MS-6020 is very similar to scopes like
AARON / APPLICATION BS-615 BS-310 BS-612 BS-620 BS-625 & the HUNG CHANG OS-650   

the two big clues are the layout and the same CRT part number

if you google image search on
"BS-612" oscilloscope
you will find a series of schematic images from www.radiomuseum.org (http://www.radiomuseum.org) which I believe will be very similar to what you have.

Thanks for your help Harvey,   
The pictures do indeed look like my scope.  Unfortunately the pictures on the Radio museum website are small unusable PNG images of the schematics.  Fortunately, once you pointed me in the right direction I was able to find useable schematics on the BAMA website.
Thanks again
