Manley Chinook Owners Tube Rolling

Are those tubes amprex?

I got mine here. Huge upgrade.

yes parts connexion or percy audio both sell them.

yes, bugle boy amperex tubes.

Keep in mind that only one of the tubes per channel in the Chinook (6922, I think)  is actually being used for gain and is therefore likely to have an affect on sound quality. The other tubes in each channel are used as part of fancy Cathode follower output stages. Cathode followers add no gain, and usually have little to no effect on sound quality, so long as they are in good working condition. Also, I would agree with others who suggest that you listen to your unit extensively before thinking about tube rolling.

Thanks All,  Will Listen first:)
