Why is it that some folks list 6L6's at 23 watts and some list them at 30 watts.
Whats up wid dat?
Most 6L6's are 30 watts. Some of the 5881's and low end 6L6's were 23 watts, but that's not the norm. I always bias AB 6L6's at 70% of 30 watts, 5881's at 70% of 23 watts.
I noticed on http://aga.rru.com/TechTips/disp.cgi?file=LV/BiasAdj.tt they show 23 and on
http://members.shaw.ca/house-of-jim/Html/bias_tables.html shows 30.
I'm kinda new to this so its be confusing me. Thanx for the Input Bob.
The first one also show the 5881 as 18 watts?
There are several variations of "6L6" tubes, each with a different suffix. To say "6L6" doesn't give enough information, a suffix must be used.
6L6GCs are rated for 30 watts, 6L6WGBs and 5881s are rated for 23 watts, etc.
Russian 5881s (aka 6L6WGC) do not adhere to the original (and CORRECT) spec for 5881s. They're neither 5881s nor 6L6GCs, just kinda similar to each.
I see said the blind man.
So I've got
NOS Sylvania 6L6GC's 30 watts
NOS GE 6L6GC's 30 watts
Mesa Boogie STR430 6L6GC's 30 watts?
JJ 6L6GC's 30 watts?
Are the Modern Designation of these additional letters being used correctly? In other words are the JJ's and MB's I have really GC's?
Excellent question! I know that many of the modern tubes DO NOT adhere to the original specs. Myles Rose can probably answer which ones do and don't.
