Here it is!!
This is a stock 5150! There are NO mods necessary to run this setup. Now it will sound better with a bias mod but it's NOT necessary. I put this combination together especially for you guys who don't want to hassle with the bias mod or do not have anyone you trust to do it.
As you can see by the bias meters on the left even very hot 6L6GC's only pull about 10 milliamps of plate current where they should be pulling about 40mA ( the far left bias meter ).
The KT88's are pulling about 32mA ( the right bias meter ) where they should be pulling about 60mA. But, for you guys who are happy with the stock tone or just don't want to mod the amp then this Integrated quad with the JJ KT88's in the outside sockets and the JJ 6L6GC's in the inside sockets will get you even more low end thunder and a very fat and punchy all around tone. The only thing necessary to install these is to clip the rather useless tube retainers from the two outside sockets so the big bases on the KT88's will fit. ( Note the clipped retainer halves sitting on the amp.)
This Integrated quad runs 99.00 and is plug and play, I repeat PLUG AND PLAY!!
