[ARC5] Circuit Help Needed

[J Mcvey]

looks like it's a stable reference voltage for the feedback amp.That's a whole lotta stuff to get 250 volts!
Is that good for 300 ma regulated or something like that?
You could probably get by with one big nasty tube instead of 3 .

 Good Evening All I picked up a nice home brew power supply that has a fewitems that are stumping me.    The photoof the circuit in question is http://www.k3msb.com/temp/img005.jpg It’s 700V unregulated in and 250V regulated out.     I haven’t been able to figure out what the6SL7 or OB3 regulator are doing in this circuit.    I’vetriple checked my schematic (which I obviously had to hand draw from staring atthe innards of the power supply).
The circuit does indeed work.
