 does anyone have a good source for high value, high voltage

 Once again, thanks for all the great information. I am happy I found

[drakelist] L-4PS - Difference in Schematic Diagram

2004-12-01 Thread Sascha Starkloff 



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. 
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. 

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

I readfew 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

Hello all,

Someone gave me a x-tal set (x-tals and labels) for the SPR-4 receiver. He
thought it was usefull for my R4C, but it is not of course.
Is there anyone out there who I can make happy with these x-tals? I only
need shippingcosts payed.

Best 73, Dick/PA2DW

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.
