Snapper output tube story

Posted by M3 lover on February 17, 2017 at 10:21:26:
fin, this is what I was told by Manley staff.

The Snappers were designed with EL34s and initial production shipped with those. That is why you'll see EL34 identified on the top plate. Then they began seeing problems with quality from their supplier so switched production to 6CA7s. After some period of time they found acceptable quality in EL34s again so changed back again. That is how they are produced today and what they recommend for re-tubing. Sorry, I can't identify timeframe for the changes.

Mine had 6CA7s when I bought them and since they were strong I didn't want the expense of changing back to EL34s.
