Hello folks,
For those who might be unfamiliar, this amp has a stadard arrangement up to the OT config. It uses 2 ea OT's who's primaries are basically connected in parallel & then to 4 ea EL34's.
Looks like the power out to each OT would be 100watts. I've got to think that with 2 equal loads connected that the total power out is 100wts. With just one load connected it still looks like it would still be delivering 100 watts.
The advantage to the different OT I'm guessing is the ability to mix speaker impedances & still match them.
The actual question is whether or not the amp can be run safely with only one OT connected to a speaker. I can see it wouldn't be unstable as the OT with the load on it would still be providing a loaded Neg FB to the PI. But what of the OT with no load...
Personally I think since the primary impedance of the power tubes would be satisfied by the loaded OT, then all should be OK.
Apparently Marshall claims it can be run safely this way...just wonder what y-all think. thanx, glen
