Hello all,

            Looking for a few H38 ballasts for some springtime projects I have lined up. Prefer
NOS, but used, working would be ok, too. Also looking for (and I know it's long shot) a can style ballast for either (or both) 100 watt MV & a 175 watt MV.

Thanks,
bob

Hi Colin,
          Since the time I posted, I've snagged 2 100 watt ballasts off eBay. Not dirt cheap, but reasonable. I think that's your best option. what's your ebay user name.....so we don't get into a bidding war with each other   Mine is rja1

best regards,
bob

I have a free 100W merc vapor ballast (H38) with a metal capacitor, it is NOS. $10 shipping and its yours. Though it is 480V only (not multi-tap)  or can be used to get 60V output as a step down transformer.
