I think I will just poke the components leads through the tags and solder not wrap and solder!
More experiments needed on the biasing?

Definitely!
Anywhere you read. "Make a good mechanical joint by wrapping the wire around the tag with pliers. The solder is there to complete the electrical connection," just forget it. A quick blob of solder is all that is needed, especially when experimenting. You need to be able to take the joint apart without overheating the other components as you struggle to unwind your beautiful wrap while keeping it molten.
The good-joint technique is for when making a final version that you want to work reliably for 20 years. But not for the lab where you may change your mind about something after 5 minutes use.
Yes, please experiment with the biasing! You won't hurt the triode, even if triode bias is zero. The pentode won't like under-biasing as the current is only limited by the output transformer's DC resistance, so a bit of care is needed (but unlike a transistor, the ECL80 will not see instant death).
