Default Wobbel Messplatz Curve Tracer WM-20

Hi Folks

I have a WM20 which the Signal Generator has given up the ghost along with some other issues

I'm curious to if anyone could point me to a service manual for this beast, it looks rather like an piece of older HP test equipment as first glance.

Unable to find anything so far so any assistance would be appreciated, I dont really want to bin it

Cheers

MM

I found this link: http://www.tube-classics.de/TC/MyEqu...tequipment.htm. It at least tells you it's made by Wandel & Goltermann.

Looks a nice bit of kit. Telford show the manual for the WM50 - http://www.telford-electronics.co.uk/manual.php?alpha=w but give (forgotten his name, Phil??) a ring, he's very helpfull.

Ahh, so you ended up with the one at Sunday's garage sale. Well done, they are a very handy widget - the sweep generator is grunty enough to drive speakers directly - I use mine for alignment when doing compression driver diaphragms etc. Sorry, have no data. Strangely the sweepgen is temperature sensitive and sometimes doesn't kick off on very cold days (hardly an issue in sweltering Aucks at present).

Apart from which, unless you're a German speaker, that's a wonderful name for said kit!
