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
=20
Does anybody know why there is a difference and maybe the type and =
rating of the additional resistors?
=20
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
