Ronnie,

I don't have a 90801 but I'm sure I could figure out what to do with =
those terminals if I could see the schematic.  If you don't get an =
answer send me an electronic copy.  but do it today (12/19) as we are =
leaving for a Christmas trip tomorrow morning.

73,

  well I have become the proud father of a fairly nice 90801. I plan on =
using=20
  this for a driver for a 813/805 homebrew rig.
  all I have is a schematic and there is a might of confusion here.

  There are two terminal strips on back. TB-1 and TB-2

  the schemtic  shows TB1 to have ground, -, 6.3v, 1(???), LV and HV. I =
think I=20
  can figure out those voltages for a 6146. I would like to know what =
the=20
  terminal marked I or 1 is for?

  Now.. TB-2   what goes here? I see where it is marked 5763 C-, Screen=20
  resistor, screen, 6146 cathode and 5763 cathode, then ground.

  HOW does one hook everything up to this?

  I have a power transformer that is 800V centertapped that should give =
me what=20
  I need, though maybe lower B+ than I would like, but it will suffice. =
All I=20
  will need is perhaps 20 watts of drive for the Class C 813's

  hep me hep me

  Everyone have a very Happy and Safe Holiday Season

  Thanks in advance
