Bear me in mind for an 88 tube only Steve if there is one going cheap?
Mine will do about 850mW max

Thanks

Of course I want to see the oldest one in the room! Could be a nugget or two in there.

Done as a preregulator, they work just fine. Done as the sole current limiting element, well, you'll have issues. They have a huge inductance, and lots of stored energy when in series with a plasma tube. Yet done carefully, this design of PSU will usually fit in the OEM LEXEL laser heads.

Laser ionics used a water cooled graphite resistor as the preregulator on their power supplies, this is not a new method.

That is possible, if he purchases the lot.
