Besides, if this is for VCFed, wouldn't they be tax deductions for operating expenses?

I recently replaced my garage/workshop fluorescent lights with LED lighting. They have a similar form -- long tubes -- but they give off a much brighter and whiter light. Food for thought.

That's why I mentioned 3M #2080 (blue tabe with orange labeled core). It's also got an adhesive that won't mar the paint it covers nor does it leave a residue that must be removed. *IF* a paint has excessive solvent nature, I go with automotive masking tapes but interior latex wall paint is not that type of paint.

More Heath manuals
by Richard Cini 09 Mar '16

09 Mar '16

All — I was able to obtain a Heathkit H11-2 parallel module and manual, and the H11 system manual. Each contains the diagram booklets, which is pretty key. Both are pretty rare from what I can tell. I’ll start scanning them and will post them to my site this weekend.
