News sites are reporting Rush Limbaugh has passed away. I have mixed feelings about this, I really didn't agree with him on anything, but I'm saddened by his passing.

This lamp needs an actual ballast that can supply a very specific starting voltage and then drop down to its operating specs. It is a mercury vapor discharge lamp and just supplying 30v @ 1A will not work. here is a link to a spec sheet for the ballast that runs this lamp...

@jrmichler is correct on the knob. 2 normally open sets of contacts, one set operates in each direction, with a spring return to center (off). I can't find what the contacts are in the ebay listing though. Is the ebay part one you are looking to use to replace the other one? if you need...

I believe that the provider (Dr,hospital,spec) negotiates with the insurance carrier for reimbursement rates for each plan the carrier has, and uses that and the co-pay to determine if it is financially logical to accept that ins. Recently an ins. carrier wanted a cancer care center to start a...
