I have 4 two tube 50+ year old T12-30 36 inch fixtures that have the old magnetic ballasts - 
one has a failed ballast and looking for magnetic replacement ballasts looks like they are close to non- obtainium. There are plenty of "electronic" replacement ballasts - 

Philips Advance Ballast RELB-2S40-N 
3.6 Ballast shall comply with the requirements of the Federa l Communications Commission (FCC) rules and regulations, Title 47 CFR part 18, Consumer (Class B) for EMI/RFI (conducted and radiated) 
2.5 Ballast shall be high frequency electronic type and op erate lamps at a frequency above 42 kHz to avoid interference w ith infrared devices and eliminate visible flicker. 

I read the paper by W1MG on Home Depot selling "industrial " ballasts vs "residential" but nowhere does it say a "residential" ballast is in fact RF quiet in our uses. 

Anyone know if if this Phillips RELB-2S40N is quiet . Are there any brands/part numbers of "electronic" ballasts known to be RF quiet ?
