NAD: SUNN Coliseum 300

big +1 here. i have a "silverface" Coliseum and it is a beast in every possible way.
LOL.

What kind (how many) cabs do you have? If you have two 8x10s or 4x15s, you will never need another amp.

One of the top 3 bass sounds I've ever heard in my life was a 70's P-bass through that amp. (through a 2x15).

Between that RD and the Sunn, you don't need anything else. (cept for the cabs)

No offense intended, but if you can't make a Coliseum 300 and and RD Standard work for you, then it's time to take up the clarinet.
 
It's a shame yours was damaged in shipping. Sorry to hear that. You should definitely try to find a way to get it sorted out. It's an awesome amp. It's one of the last things on my "gotta have" list.
 
I'm just wondering what could fall off that would prevent the amp from putting out it's full power?

I did notice that the input overload light never came on......no matter how high the gain was set or how much I attacked the bass.

I'm wondering if it's something with that?

Everything seems to work just fine.....just loud talking volume when the amp is cranked.
 
I have a working one in my room.

Lemme know if you need any help... i might be able to help out! :)

Mines a white logo, but otherwise, they are exact same.
 
Compressor on or off, doesn't matter.
(I can get the compressor's "active" light to blink)

gain switch on or off and the gain maxed out.......no overload lights.

I can also get the power amp limit light to flash too....but it's still quiet. I doubt I could wake up a sleeping baby with this thing.
 
The "thing" inside rolling around was snapped off screw and nut. It was one of the ones that hold the fan/tranny down.

Otherwise, it's dirty, dusty and overall old....but I don't see anything inside that would indicate any issues?

I'll clean the jacks when I have time........if that doesn't work, I'll have to take it to a tech.
