Yesterday I forgot C251 and C252 on the sub PSU board. I did them today, along with re-soldering all wires ans cleaned everything.
Later today I went ahead with the new binding posts and speaker wires. I bought some professional gold plated terminals from CMC. I had some Van den Hul Snowtrack speaker cable lying around and thought that I could use that in the B-2. Maybe it's a bit over done, but I like it. I actually use the same wire as actual speaker wire between amp and speakers.
For the binding posts I made a plastic (not sure what the real english name of the material is) plate which comes at the place of the original speaker terminals. After some measuring and drawing I drilled 8 holes of 9.5 mm. The binding posts are 8 mm, but then I had some room to get them aligned. I chose to mount the positive terminals all the way up in the hole and the negative all the way down in order to gain full strength of the metal back plate.
I crimped 8 mm gold plated rings directly on the bare wires with a small amount of solder for strength. The gold plated rings are directly mounted on the binding posts for maximum conductivity.
The plastic plate mounted with painting tape in order to draw on it:
Make sure to start with a small wood drill (2 mm), after that in small steps to 9.5 mm with metal drills:
The final result of the plate after sanding:

End result:
I already test fitted the power board. No problems with the thicker wires.
Next up: the Triac switch, because one connection of my power switch has broken off.
I already have the parts and the schematic, but I'm not really sure how to wire with those two transformers. I'll have a look into that.
