  • I bought this vintage tube amp...

    Here's a Maas-Rowe Carillons Model 500 50 watts church carillon tube amp.



    Can anyone give me some pointers about that speaker output? What is it called and how does it work?

    Cool! Looks like a PA amp from a church. Looks like you're missing a power tube. It has a tube rectifier. Looks to be 2 channel at about 35 to 50 watts per channel but the channels share one preamp. If you're thinking about making this a guitar amp you want to either take it to a tech or use it as a base to learn about building/repairing amps yourself. Lots of old PA amps have been successfully converted to great sounding guitar amps.

      this is a Carillon amp, designed to run a set of church bells. I repaired these when I was in High School....which was the last time I saw one.  These are not unlike 60's era Bogen school PA amps (which I also worked on). These amps are not easily modified for modern musical use or hi-fi, but it can be done...the output connector can be replaced with an XLR or a 1/4" jack, but check the resistance and wattage before you hook a loudspeaker to it! THE output resistance is variable depending on how it was connected. The chime out put has a fixed output resistance,...IIRC there are two other modules tha tshould go along with the Maas 50W...but I could be wrong, it has been a long time...

      I don't have specific specs/diagrams available, but I converted some of these as bass amps and PA amps in the past...they generally do not work well for guitar, although they could be repurposed, I suppose. Oh, very wary of the capacitors on  that beast!!!
