    Secondary 2:
    6.3Vct, 6A.
    Secondary 3:
    800Vct     (400-0-400)   At  about 200mA.
    This is a fully tested, used item.
    It was carefully cleaned up, primed and repainted with a semi-gloss black for OEM look.   Looks very good and clean.  No damage to the case although minor blemishes show.   Electrically, transformer was tested for proper voltage and leakage resistance. I will not sell knowingly bad or inferior items.
    Bench testing of the HV secondary
    showed the following B+ readings, with an input of 117Vac.  Your line voltage will probably vary some.    Using two 1N5408 diodes and a 50uF filter cap, no load B+ was 585 Vdc.    Then,
    was 567 volts at 28  mA,
    was 564  volts at 37 mA,
    was 559  volts at 50 mA,
    was 558  volts at 55 mA,
    was 553  volts at 67 mA,
    was 535  volts at 133 mA,
    was 525  volts at 173 mA,
    was 518  volts at 205 mA, finally
    was 506 volts at 260mA.     Use this as a rough
    guideline
    for your application.

    Overall, approximately
    4 ½  x 3 3/4  x 4"  tall,    ~ 8 pounds.  Sits about 3" tall above chassis.
    Four 8-32 mounting screws.   Requires a chassis cutout for mounting.  Can also be mounted to a base or chassis with four (not included) 8-32x1" metal spacers.
    Useful to anyone
    who works on tube circuitry, for proto work, new project or repairs.
    This is a hefty, very well made transformer
    that should perform well for you as long as transformer ratings are observed.    However, since I have no way of knowing the life expectance of old electronics or your application, I must sell As-Is.
    No Returns.    No Refund.
