Does anyone know whether this amp outputs 50 watts in 8ohms, or 50 watts in 4 ohms?

That amp doesn't support a 4 ohm load, only 8 and 16. It does 50W at 8ohm, probably around 35-40 at 16ohm. Just a guess though, the manual doesn't state the wattage for 16.


Edit: The manual is a little confusing, because the combo is different from the head. If you have the combo it will support 4/8, so for that it's probably 50W @ 4ohm. Not sure why they would do it that way if it's the same amp...

If the amp is a 50 watter, and has a 4 ohm and an 80 ohm, it will still put out 50 watts. The only time that it changes is when the amp has a stereo mode.

2 EL34's are capable of putting out 50 watts in push pull configuration, and that's what they'll do.
For example, a common PA poweramp can put out 1000W at 8 ohms bridged, and 500 watts at 4 ohms stereo.

A mesa boogie triple rectifier can put out 4, 8 and 16 ohm modes. it will still put out 150 watts at 4 ohms or 16 ohms, because the output transformer determines that. A valve junior has taps for 4, 8, and 16 ohm, but no matter what you use, it will still put out 5 watts, provided you use matching speakers.
