<strong>The</strong> 7868 is very close to the 7591 and 6GM5 electrically. <strong>The</strong> 6GM5<br />
is a 9 pin also, but not pin compatible. <strong>The</strong>re is an article by<br />
Gary McClellan in Glass Audio, April 1996 ("Yes, You Can Substitute<br />
for the 7591 Tube!") that compares these tubes and a couple of others.<br />
You can find a little data about the 7868 on my web page:<br />
