PL700 Rebuild

Will do thanks for the help

You have eyes of an eagle @Sunnbobb, three of the four were close to 10 ohms however the one you pointed out was 34 ohms.
10ohm 500mw 1% ok here or step up to 1 watt?

Found a solution for the turrets and lamps as well.
Ordered 10ohm 1 watt metal film resistors

Yes, I went with 1w as well.

On the units I've restored, I've gone ahead and replaced the 10W resistors on the back plane. Every one I've replaced has been out of spec. Just a thought.

I meant to say 10 ohm..

 

[Overundr1]

figured that yes.

Power switch and arc suppression?
Is there a forum approved switch that both looks period correct and can handle the current, also could use a ac snubber cap or perhaps a cl-80 style to tame the input jolt to the mains?
Hopefully get the bias resistors for the back plane today

While cleaning up wiring noted the ac line to the original switch had extremely dodgy soldering (weak connection) so add that to the list of things that need to be checked for safety when working on one with unknown history. Have found more poor/cold solder joints on this amp than any of the tube gear I have been through btw.
