tell me about the Mark III Coliseum

[Neeklaus]

thanks for the awesome info guys!

 

[Neeklaus]

hot damn, i just scored one.

 

[mentoneman]

more confusion
I had the mark IIB coliseum 300 series which I had modded to simulclass at mesa hwood

ran 34/L6 for a while, but in that amp preferred all 5881s

the 295 and 400 power amps could also run 34/L6 combos but you have to remove ghe chassis lid on the 295 to fit/accomodate the taller 34s

395 could not run both tubes without modding.

Congratulations ..... that is my favorite Mesa amp of all the ones they have made. Just a great amp.

 

[mentoneman]

hot damn, i just scored one.

just a though
these amps can sound weak if not retubed with freshies
if you have the capability you could have the seller send to boogie for a factory checkup
then boogie sends you good as new and screaming!

[Neeklaus]

[stephen sawall]

Looks pretty clean.

.... I still plug in my Mesa amps from time to time.

 

[blackba]

Very nice It looks like it has the R2 volume mod, which is a good thing from what I have read.

 

[Duke309]

Looks like a great amp, R2 volume mod will be nice. I still need to do that to mine. That will be expensive to retube though. Speaking of which i need to retube mine

 

[stratotone]

Mine is a lot rattier than yours...

how does simul class work? 4 6L6s and 2 EL34s?

Is there a Simul Coliseum? Every one I've seen has just had a "Full Power/Half Power Switch" and they were all 6L6s.

Yes, I am the original owner, and bought the amp new in 1986. I have the 13th one of approximately 200. It is Simul-Class (Was an option) but is Simul-Class--ALL the time... There is no way to disengage the Simul-Class circuit like on the regular MKIII line (which has the Class A or Simul-Class Modes switch on the back panel).

I can run all 6L6s, or the middle 2 tubes, can be exchanges w/ (2) EL34's. It's 180 Watts

Holy Shit! Look at the size of the PT on that bitch! Did they use that PT on the Coliseum heads exclusively? That think must weigh a f**king ton!

Yes, exclusive to the MK Coliseum

Yes, heavy... In the case it weighs nearly as much as an SVT-- but as our friend mentoneman says, "Big tone is-- Heavy".

Believe it or not, a Randall MTS head is even heavier.

+100 on that! I lugged mine around enough I think it gave me a bad back!
