Is your EDCOR 15k:600 gaped?
here is a quote from the auction listing:
here is a quote from the auction listing:
These transformer are special design custom made for Tube Pre-amp. ( 6dj8. 417a. 5687 ).
The Transformer Core is Z-10 with air gap .It allow dc. current not over than 30ma. So the pre-amp circuit do not need any expensive couple capacitor.
Primary impedance : 15k ohm ( DC.current not over 30ma.)
Secondary impedance : ( 600 ohm series ) ( 150 ohm parallel )
Frequency Response + --1.5db 20Hz-----25K Hz
Weight 1 KG. with packing.
