[Boatanchors] 6550 tubes

[w6om at cox.net]

The 6550 is a popular tube out here on the Left Coast with Am'ers as 
replacement modulator tubes in the Viking Ranger.

You need to crank up the grid current to 90 mils but once done stand back. You 
have a Ranger that sounds rich, full bodied and like a commericial broadcast 
station.

I did it in mine and could not be more pleased.

Enjoy
