It's a matter of semantics. :-))
I usually rate them as EXACT, GOOD or Doesn't Exist.
In a pinch, the substitutes listed will work, but certainly not as well as the 6HS6 which is far superior than the subs mentioned.
Yes, I have tried them and do work with degraded performance...I'm an old tube swapper from way back. ;-)
I have never seen a 6HS6 bite the dust. Again, just to feel safe, buy a spare or two...As I stated in my original message.
I'm kinda partial to Sylvania, Mullard and Amperex.

Jay -
Have you actually used any of those subs in an R-4B or other receiver?
I'm curious, because I've not had much luck with any of them. In the Premixer stage they all give a slightly lower output but aren't too bad, but in the First Mixer the gain and AGC characteristics are altered significantly.
Based on my experience, I would consider them "fair" subs at best! :-)

6AG5
6AU6
6BA6
6CB6
My advice...Locate some more 6HS6 units.

hi,
I find myself with only 2 good 6HS6 spares - just wondering if there are
replacements or equivalents for this tube or should I look for 6HS6 only.
This is for my R-4B.
Thanks!
