Half power switch

I looked, but I couldn't find any info in the repository about adding a half power switch.
Would anyone have a diagram handy, ( for us non-schematic reading newbies), or just some directions.
Would a 6 amp toggle switch be OK in that application ?

Many thanks ...sully

I presume you're talking about your Valve Junior, but it wouldn't hurt to tell people which amp you're referring to Especially with this being the 18 Watt forum! :D

Anyway, this post in the big VJ thread should yield your answer:

This is for a switchable pentode/triode mode which will reduce the power to approximately half.
