[time-nuts] FTS 1050A What to do??

[paul swed]

no pix needed. Manuals fine
Thats quite a nice oscillator. 20 watts ac and 8 watts DC. That makes a nice
reference indeed. Easy to run on battery. The 20 W on ac is because of the
transformer and regulator inefficiencies. I just changed a xformer out to a
switched lo noise supply. Went from 16 VA to 3 VA no load. Nice power
savings for a 7X24 thing.
