Tone arm holes do not line up - best way to attach TT?

you are going to have one shot at the hoop with tape, there is no second chance at proper location. think about some sort of guide pins to get it exactly right the very first time.

drill new holes, or acquire a new arm board (if your tt uses arm boards) and have that drilled according to the template.

double backed tape will work, but it’s like using it to attach your phono cartridge. it will compromise things. the precision will be reduced.

i know Haas turntables exist, but somehow cannot find one to look at by searching. do they use arm boards? or is the tonearm base screwed directly to the plinth?

Another way to go might be to find a thin template of wood you could screw down into the existing arm pod, that would accept wood screws to attach the Reed. You might need some washers to avoid the screw going too deep.

this is assuming you have sufficient play to adjust VTA height, it would still be less than ideal but likely better than tape. The least bad approach.

the top of the arm pod is not big enough to allow tape to fully grip the Tonearms base.
