Just looking at the welwyn w22 screen resistors. The data sheet states they are rated at 200V. The 10 watt version is rated at 500V. A little long to hang of a socket tho..
My 71' SL/A has very similar ones in it that have a 'W' in a circle, im guessing that welwyn has been around a while.
Over at Metro, they have these in their store as screen R's. These are the same type used in many wrecks, so does the 200V mean anything?
Im starting a plexi build in a tweed 2x12.. cant wait to have it running, i had it dummied up with cement R's but those green welwyns look very cool
Welwyn screen resistors voltage rating?

Re: Welwyn screen resistors voltage rating?
Volatge rating is across the resistor. A typical screen R will only see 20 to 40 volts across it, so a 200V part is fine.Just looking at the welwyn w22 screen resistors. The data sheet states they are rated at 200V.
Now part of the TT electronics group, Welwyn Components have been around for more than 70 years...My 71' SL/A has very similar ones in it that have a 'W' in a circle, im guessing that welwyn has been around a while.

Ahhh sooo. Cheers!
Welwyn
I started my working life at "The Welwyn" in 1972. I actually worked in "A" factory , where they made the vitreous enamel W series. Back then they were in a town called Bedlington - N.E. England. Their name came about because they first started up in Welwyn Garden City. They were always conservative in their resistor ratings (V & Pwr). Nice to see they are still around.
