UPDATE:
Just put the eminence governor speaker in and took out the G12-85. The Celestion had a lot of movement (since it has been used since 2001) and the new gov'r speaker was really stiff (since it was new). I thought it would have an impact on the sounds, but I think it sounds great so far. And if it will only get better over time (break it in) so be it!
Installed the Weber Beam blocker. Now when i crank it up, it sounds as if the sound is more dispersed and not directional. I'm not dropping my jaw here, but it does what they are meant to do and I like it alot definitely worth the money.
Replaced tubes and rebiased. It had winged C Svetlana EL-34 power tubes and Groove Tube 12 AX7A's. I replaced them with JJ ECC83S preamp tubes and JJ EL-34L power tubes. The Volt Meter was supposed to read 42.5 or so and it was reading 49.5 (too hot). The tubes were a nice orange and not red so I twisted the microadjuster just enough to where it read 42.5. Different than biasing a Marshall but very easy on the Rivera. But it's nice to know if I ever need to put my backup tubes in, it will be running cooler than hotter because I had to dial it back.
When I first plugged it in, a fuse blew after about 5 minutes. I've had problems in previous amps (Peavey Classic 100) with the 2 quartets of EL84's cracking near the pins and blowing a fuse and needing replacement tubes. So I checked all my tubes to make sure they 1. weren't broken and 2. were seated properly. I replaced the fuse... and its been working great ever since.
I had the chance to compare the eminence Governor to a 4x12 Vintage 30 Marshall Cabinet, and I thought it was pretty close. I consider that a compliment to the Eminence Gov'r because A. it was cheaper, and B. it was made in the US. One thing I'd add is the V30 has an ear piercing knife edge shrill tone that needed to be dialed back, while the Gov'r it was not necessary to dial back anything on the amp.
SUCCESS! Will post to youtube whenever I get a chance.
