[time-nuts] pts 160 power problem

[EB4APL]

Hi,

Since this thread is about a PTS repair, I think this is not too much 
OT.  I need the manual for my PTS 040, I already have one for the 160 
from Didier's site and while both models are similar end employ most the 
same modules, I would like to have the specific one for my model.
According to PTS web site this model is still on production, but I think 
that asking PTS for one would cost me much more than I paid for the real 
thing.

If anybody knows were I can get one I'll appreciate very much.

Regards,
Ignacio, EB4APL
