Telefunken M10 Bias

[Henkk]

Hello

I'm Henk and I'm trying to get my m10 up and running.
The Bias to the erase head is not a nice sinus but is distorted.(att 1)
The rec heads have an ok bias.(att 2)
The schematic of the V396 c card (att 3)
Ts1 and Ts2 get very hot but I pulled them out and they seem ok(ohm meter).

Is there someone who knows what is going on here?

Thanks Henk
