Sascha,

the L4PS schematic I have is the one for the type L4B-1 (on the front =
cover).  The resistors shown across D1 through D14 are listed as R13 - =
R26, 150K, 1/2 watt.

  Hi,

  I downloaded a schematic diagram for the L-4PS (Power-Supply of the =
L-4B).
  I compared it to the one came with my L-4PS.
  There is a difference in the resistors used in the =
high-voltage-generation.=20
  My schematic tells me there are no resistors in parallel to diodes D1 =
to D14 - but the dowloaded schematic is showing one resistor for each =
diode.=20

  Does anybody know why there is a difference and maybe the type and =
rating of the additional resistors?

  I read few days ago drake changed the output-voltage of the L-4PS to =
about 3500V in the last few PS ever produced. Is that right? If so, does =
anybody got a schematic of the changed PS?


  Thanks, 73's
  Sascha
