Clarke Hess Model 828 Calibrator search for documents

[Detzi]

Hello there,
i have laied hands on a broken Model 828 Calibrator    which only gives around half the output it is supposed to. I openend the device and there is nothing obviously broken. To make things easier, it would be nice to have schematics and or a service manual. I already E-Mailed them but got no response. If you have acces to such documents, i would be very pleased if you could share them with me.

Good find Try searching for RFL 828M (RFL made them before Clarke Hess). I do have a copy of manuel but need to work out attaching it (too big, and this is my first post!!!) and cant remember where I found it on the web. Mine had the ramp up knob smashed into theswitch board behind and transistor on the rear panel with dodgy connection. The manuel I have gives theory of operation and some basice waveforms to check, I have not found a full schematic yet.

  thank you very much Sir! 
Having Signals for the Testpoints is great. That will help me very much!
A list of used parts spares me the eventual search and can be used as a quick reference.

That manual is a hell of a lot better than starting from scratch
