Has anyone done the magnum upgrade to an 88 amp? How did it compare to the stock 88?

Buckingham: E80CC is not a direct replacement for 12AU7. They often come up on Ebay offered by sellers in Europe. I am looking into modifying a Pilot 232 power amp to run one in place of it's 12AU7, hoping that it will flesh out the tone a bit (make an EL84 amp sound more like an EL34 amp:-). The E80CC uses the same pin out (I think) and it is taller than a 12AU7.

Bradz, the tube can be bought at the tube store, and Dekay is right ,its not a direct replacement, but you can use it in the 66 after you have Mark change the fuse out on the line stage. If you don`t do this it will blow the fuse after a few days, and you will end up changing it . The sound of the unit with the tube in it is awesome , the bass is tighter the mids are about the same ,the top end is extended. the tube also sounded to me more transparant. It also has more gain, the dynamics are much better. You will like the Magnum 66 on its on , but that tube is very good, another tube to try is the 7316, I have not tried it , but the word is, this is a good tube as well. Do the Mod and you`ll like the unit much better.

Bradz , also the unit I have is a Magnum 66, and it does not sound as good to me as a stock 99, very close , but no cigar. The 66 Magnum is a very good pre-amp, much better than most of the others out there, it just not going to keep up with the 99, and if you do the magnum on the 99 , well you right back to the begining, the stock 99 will sound way better than a stock 66, same goes for the Magnums too. I have the 88 ,but I don`t have the magnum of that unit , so I can`t say much on it, I `m going to do it soon.

Drumsgreg, so if I was to upgrade my 66 to the Magnum version and with the mod you mentioned to use the other tube, would the cost be $250. or more? I've been pretty happy with my 66 so far and haven't done any tube rolling so, I think the upgrade to the Magnum 66 instead of going to a 99 would cost less and worth a try. I noticed on your sales feedback that you use to have Maggies and sold them to someone. Did you happen to have the 1.6qr? I'm using:Cary 303/100 cdp->Coincident cst ic.->Rogue 66 stock->Coincident cst ic.->Odyssey Stratos w/ cap upgrade->AP Oval 9 biwired->Magnepan 1.6qr. I've also considered adding a Rel sub with the maggies and think that it might be a better upgrade than going from the 66 to a 99. What would you think?
