AX84 Moonlight Amp Build Project

Those tagstrips look very similar to what I used in my AC15 build.

I could get up to 3 leads into the holes on each side of each lug/tag which made things a lot easier on real estate consumption... 6 component wires per tag and then the huge hole in the middle for big multistranded cables from underneath came in very handy ...

My only concern was voltage rating between lugs wasn't specified by my supplier, so I ended up leaving lugs vacant when next to any lug with any sort of anode voltage or higher HT on it... Low voltage lugs like cathodes or decoupled tone components I felt were fine when next to earth lugs.

Yep, that would be a concern, you definitely don't want the voltage between two adjacent tags to end up exceeding the dielectric-strength of the insulating material and causing a leak, especially if one tag happens to be the one with the negative grid-bias supply for one of the power valves, I'm not sure what the dielectric-strength of Phenolic is, I think it's something like 300V DC or so per so many milimeters, or I could be wrong, on the other hand FR4 Fibreglass will definitely have a higher dielectric-strength.

From looking at the pic of the tagstrips from Evatco, it looks like they're made using FR4 Fibreglass.

Edit (04/05/2023):

Seeing as I just recently ordered a set of 10 of these 28 X 2 tagboards from Evatco, I can confirm that they do indeed use 1.5mm thick (roughly) FR4 Fiberglass as the insulating material, the tags themselves looked to be tin-plated and fastened to the insulating material via brass eyelets with an inside diameter of about 3 or 4mm, this is actually a good and useful thing since brass is solderable so you could use the brass eyelets as well as the tags for mounting components and wires, this gives you more layout options.
