[R-390] B+ Ripple

[quartz55]

I'm getting less than .01VP-P ripple in general on the 2 AF/PS modules I have.  However, I seem to be getting some jumps, but they are still less than 0.1VP-P.  I'm wondering if this is a typical thing, or maybe it's something on down the line?  Both AF/PS modules act the same in the same radio.  I can see the jumps on the DVM as spikes on the 'analog' display part, but on the scope, there doesn't seem to be any relation to timing, it just randomly happens to jump, maybe once a second or so.  I'm measuring at C606 pin 5, the DC volts is around 200-205 and I'm using the rectifier tubes in the PS with thermistors in the AC line.  New caps mounted under the chassis.  Comments welcome.

Actually I've got 3 of those thermisors left, I ordered too many.  If anyone wants them, let me know, just mouser price plus postage, I could probably send them in an envelope but I might have to add $.20 for un-machineable mail. CL-90's.

Merry Christmas everyone.
