Hameg 205-3 broken!
This morning, whilst I was grappling with an Italian FM generator (and that's a story in itself), my trusty, owned-from-new, thirty year old Hameg 205-3 'scope failed! Suddenly, no timebase at all, and swinging the X-pos control from end to end moves the spot very, very slightly from side to side. I suppose it's a power rail or something of the sort. Fortunately, Rhode & Schwarz offer the manual for free download, but still...

Re: Hameg 205-3 broken!
Well, it looks like that was a simple one. The manual sensibly suggests a careful internal inspection and re-seating of connectors. Nothing obviously wrong, but I did re-seat a thick ribbon which looked a little loose. Turned on with meter at the ready, and was greeted by normal operation! Turns out that ribbon carries the drive to the deflector plates...

Pleased it was a relative easy fix as I've always thought that reliability is one of the great strengths of Hameg analogue 'scopes. I've been using my 203-5 today which, touch wood, hasn't missed a beat since I bought it a few years ago.

Re: Hameg 205-3 broken!
I've certainly used mine - all that's really wrong with it is a that a couple of BNC sockets are slightly loose and the coupler for the timebase trim pot has the usual fractured hub - I'll replace that with a metal coupler in due course. Not at all bad for somethimg I bought around Christmas 1990...
