Pioneer SA-708 amp - Power Transformer secondary voltage

Hello,

This great amp has transformer shorted on primary (it worked for many months).
I would replace with a toroidal, however not sure of secondary voltage.
My guess is around 2 x 30V AC, but schematics do not show this.
I see in the schematics raw DC around 43V.
Anyone an idea about this ?
Tx !!!

Hello
Tx for your answer.
I was lucky : had a similarly shaped spare transformer 2 x 35v @ 3.6 amp
Put it in place with a diode bridge of 6 amps and it is singing again !
And I swear that the sound is better, louder and more dynamic
Raw voltage is slightly above than in the schematic
All is well
Tx again

Hello!

The secondary voltage is around 2 X 35V AC, because the schematics show 46.5V and -46.5V in collector of Q1 and Q2. I hope it works!
