Title: Matching tubes?
Post by: corndog71 on November 01, 2013, 04:08:26 AM

I just ordered a Reduction kit and after reading a few posts about one tube being louder than the other it got me thinking about getting matched tubes.  From my limited knowledge I remember hearing/reading that voltage gain stages should match in gain but cathode follower stages don't need to be matched.  Could someone tell me which triode sections should be matched in the pair of tubes for Reduction?

Reduction uses two dual triodes as Seduction did.  Each tube is its channel'sl two gain stages.  Neither is a CF stage.
