Sony/Tamradio Output Transformer ID

Good day all,
trying to inventory my transformer shelf and i have these output transformers which were pulled from old Sony RTR years ago.
unfortunately, i can’t remember the model. They were definitely 6aq5 single ended and look almost identical to the Tc-500a outputs.
The housings have no numbers stamped on top, only at bottom rail there is a ink stamped #370117. It does have 600 & 8 ohm secondary taps like the 500a
and similar resistance readings.
Are these in fact Tamradio outputs and has anyone come across these before?
Regards,
Susnick

Measure the turns ratio applying a small ac voltage in the secondary from another traffo. A 5 or 6.3vac suffices. And measure the primary voltage taking in mind that 200-300V can be. Measure it using a vom ans coccodrile clips avoiding take contact with your hands. Usually a 6AQ5 or 6BQ5 use 5K to 8 or 3.2R.
