Default Harman Kardon tube Power Transformer ID

Hi all,
new to the forum,
was wondering if anyone had the wiring ID or a schematic
that had the wiring for a Power transformer labelled
FT2362705E and 1052 848, that came out of a Harman Kardon.
(it was either a Pre/power amp, or a receiver, but i do not remember the model #)

It was mostly trashed and when i pulled them i wrote some stuff down, but not all of it.
It had 2 dual El-84 outputs, 6 preamp tubes, and i believe a 5ar4 rect.
Output transformers had 8/16/32ohm taps.

any help would be great

Hello Voxacthirtee, I am going to guess that the amp you took apart was a H-K A224, also called the trio. I know the amp, as I have one in my basement my father bought a year old in 1960. If you send me your email address, I can email you a .gif of the schematic that I downloaded from the net. And if you have the output transformers and are interested in selling them, I may want to purchase the OPTs.
