and don't forget to apply some dielectric grease onto the rubber nipples.

reiner,
honestly you can't really do much to this device. Sometimes you can prolong its life with replacing the main capacitor (the blue cube thing under the black plastic cover; but read below), but very often it turns out that it's just an old horse: the coils are bad, the transistors are burnt. You know what they do with old horses.
And it's the epoxy on the PCB which doesn't allow you to do anything there and which will make you destroy many chips and pcb traces while trying to dig into scrambling thru this naughty thing.

Zig

P.S.
Yep, C900 bulletin board features the best geeks and specialists over the whole TSN, but you've got to try your own 'NG900 & OG93' one first before dubbing your post here. Die Ordnung muss sein!
See the BB list on the top of the web page.
