HARBUCH ELECTRONICS - Toroidal Power Transformer
Made in Australia (Sydney)
I suspect Harbuch is going through a period of "transition" as their website appears to be only partially active and I read somewhere that the original owner (Rod) was retiring
Model: ANTRIM A2413/F
15VA Total power output capable
Label on one side of the core reads:
HARBUCH ELECTRONICS PTY LTD
ANTRIM A2413/F
PRI-240 ORG-ORG
SEC1 15V/0.5A RED-YLW
SEC2 15V/0.5A BLU-GRY
(Old Australian Made "Boomerang" graphic sticker to the right side)
DUAL (Fully isolated) secondaries:
15V @ 7.5VA (around 500mA full load) EACH Secondary winding
Epoxy "POTTED" centre of the donut with a drilled 4.75mm diameter hole for the mounting bolt
NO mounting hardware supplied (rubber or plastic discs, metal disc and central bolt) BUT with this transformer you only need a bolt/nut
The underside has a silicon rubber "washer" formed already and the potted core is deeply recessed, which means your mounting bolt can be quite short.
This transformer was used in our production of audio preamplifiers, input stages using dual rail 15V supplies
If you do prefer to use a rubber base pad or steel top washer, I have found SOME mounting hardware and you could click HERE to see what I have at the moment.

63mm diameter
28.75mm height
All primary & secondary flying leads 180mm length
All leads are stranded wire, colour coded pvc insulation.

TESTING:
To confirm the transformer is functioning properly, I have made some simple "open circuit/no load" tests ON EACH secondary winding
ALL Secondaries measure 17.83V AC output (2)
EACH IS ISOLATED FROM ANY OTHER WINDING
