I have several tx for sale-
         A power tx, dual primaries 120/240, hv secondary 1800 ct with
taps at 660 ct. 
        (common ct)
                used silicon rect for the hv, a 5U4 for the lv.
        FIL #1, 5V @ 3A
        FIL 2, 6.3V @ 6 to 7 A.
                This brute weighs in at 36 lbs and has a 3 inch stack.
                I estimate the current capability at 900 mills or more.
                        this was used to run a pair of 7378 tetrodes,
class A  in audio service.
                next-
                              the output tx pri ct looks like about 5k
ohms, the secondary can be 70 volts on
                         one winding and 120 volts on the other, the
lamination stack is 3 1/2 inches at                                      
  about 18 lbs.
                        yes, there is an input choke - heavy, 3" stack
about 45 ohms i think.
                                any interest pse contact  jackiv at juno.com
