Kenwood 922/ Tokyo HP Plate Xmfr
Offering an OEM plate transformer for either the Kenwood TL922 or the Tokyo High Power amplifier with a pair of 3-500's. The plate transformer has multi-tap 110/220VAC primaries with 1400VCT output. Kenwood OEM part number visible in the digital. Has 4 mounting tabs for convenient chassis or side panel installation. The transformer was removed from a fully functional amplifier with wires cut sufficiently high above the solder tabs so the color code stubs are still visible to facilitate easy reassembly. Will produce 3600VDC at 1 amp in a typical doubler rectifier board circuit. Taps are also imprinted for easy ID. Transformer is also well suited for a compact, small footprint homebrew desktop amplifier project. Note:Accompanying filament xmfr sold.

Well since it looks like a total rebuild of the B+ supply...couple good components above.
Those Xformers from the old BTI amps are stout...I just recently rebuilt a 3-1000Z/BTI LK-2000 and using the FAR circuit boards...that hold the 12/filter caps...worked very well...3600VDC@34uF filtering using (4)20kv @ 3amp diode blocks for the doubler.
However the Drake rebuild board would do nicely also on either of the xformers listed above.I have a second BTI xformer which will be used with Harbach's board to make a upgraded PS for my Drake L4B...
Just remembered this is the desktop version...WOW spacing may be an issue...Most likely a true Hammond Transformer replacement may be required (They own the Peter Dahl name now)...Hold onto your wallet!!!
