Sunn Coliseum Bass manual?
Mark Marsh
I just acquired an older Sunn Coliseum Bass head (not the one with the red
knobs). Does anyone out there have a users manual for one of them? Fender
offers the schematic, but not the manual.
Thanks!

That DL is an exe. This is probably the manual:

Sadness, though.
The TC40c is a tube guitar amp manual, and the coluseum300 is a newer, biamp
version.
Oh well...

What exactly do you have questions about, Mark? I can't think of
anything I've seen on a bass amp that would require explanation...
Maybe post specific questions here, and someone can help?

Corey-
Minimum and maximum impedance load and RMS wattage/distortion at each?
Are the speaker jacks in parallel or series (I've seen amps where they _are_ in
series)?
What are the electrical characteristics of the pre amp out?
What are the electrical characterisics of the power amp in?
Like that. :-)

It's been a long time since I worked on a Sunn Colleseum bass amp, but if
you're talking about the solid state Colleseum amp, as best I remember, I
think the RMS wattage was 275 to 300 Wrms @4 ohms, the speaker jacks are in
parallel, the pre out is something like 2 Vrms max @ 1K ohm and and power
amp in is around 1Vrms for full power out, @ at least 10 K ohm, and probably
quite a bit higher than that.
Back in the early seventies I was using a Colleseum board and two
Colleseum power amps biamped into Four Altec A-7 speaker cabs with Cerwin
Vega speakers and JBL drivers mounted to the original Altec horns. The PA
was very loud and clean, we drove the Sunn power amps very hard and they
never complained. Out bass player was using a Colleseum bass rig for a while
until he traded it for the Ampeg rig with the folded horn 18. There is some
info about Sunn stuff here:

After looking at the schematic at
http://www.richbriere.com/The_Sunn_Shack.htm, I'd say with a +-50V supply,
the output power would probably be more like 250 Wrms @4 ohms, assuming a
+-45 volt swing at the output. It looks like it should be able to drive a
two ohm load as well, meaning power out at 2 ohms in the 350 to 400+ watt
range. We drove our Sunn Coliseum power amps into 2 ohms all the time with
no problems.
