The schematic in pdf can be found here

The voltage at the collector of TS20 is close to zero volt whilst the other side of R76 (1K) is at -9V. I unsoldered R76, tested R76 it and it is ok. after that the voltage came back at the collector of TS20 and could hear the HT transformer kicking in. I switched it off tried again and same thing voltage at the collector of TS20 is close to zero volt.

any hints you would recommend?

Thanks

Thierry
