Well, as least I was right on the load thing!

What value of resistive load should I use? 8ohm for example?

I am familiar with working with electronics. I am not familiar with tubes, though.

Checking the values of capacitors and resistors... I will need an schematic to know the actual "book" value, i guess. I will look harder on internet.

To check the transformers, any hint please... I dont know the specs of this transformes, hence I dont know how to check them..

This is going to be my "check and repair by wire" post. I will ask a lot in order to get it working.

Thanks
