Drake Dial Filters (Was TR-4)

[Garey Barrell]

Pete -

I tried a "stained glass" colorant once and it darkened within a few
days.  I was told by the manufacturer that their product was intended
for glass used for lamp  _shades_  and windows, not for high
temperature bulbs.

I do leave my R-4's on all the time, but I suspect they reach maximum
temperature within 30 minutes or so.

I live about 5 miles from Norcross, so may try to look them up.   By
the way, Norcross is also the site of the first Vibroplex
manufacturing "plant" !
