Hi guys,
Yesterday eavening I've checked my new TSZ07 9 Track Tape on my VS4000/90
the first time, it worked flawlessly. Later I've switched it of with the
power button on the fron paneel.
This morning the Drived stinked. A smell like an burned transformer.
I've pulled the powerchord and leaved to go to work.
Now I have dismounted the PSU and looked inside: Shit!
There are 2 board in there, the one with the big Heatsink in the middle has
on one edge an uncooled TO220 Transistor (or something looking like one)
and a wirewound resistor near by. The entire area around them is burned
black. Noch chance to read Parts values or so. The PCB is bad also, burned
to carbon. Interestingly this PSU (and the entire Drive) is still
working... no fuse blown or something. :-|
Guys I need urgently an schematic of that PSU to replace this part of the
PCB. It isn't the first time that I'm repairing switchmode PSUs even w/o
any schematic, but this one really looks bad.
The drive is a TSZ07 DEC Drive, I think it is the same as the Cipher M995S,
or the otherway around it is a relabeled cipher drive.
Regards,
Holm
