Thanks for all the info. It is cool to know the standby switch is unnecessary. I read something like that online as well when I was trying to figure out if it was added. Online said that the switch would actually cause a larger power surge than just letting it gradually all power up at once since the standby would limit the power until it was switched causing the warmed up load to hit the tubes.
Yes, but that's sorta neither here nor there. Standby switches are fine, mostly, but entirely not necessary. They're more a convenience for repair techs, tbh. They can be problematic with tube rectifiers if implemented incorrectly but on this amp its not gonna do anything detrimental to have one (other than being inconvenient to flip).

I suppose it is stupid to thing an 80 watt amp would be quieter than my 120. Honestly it is a little. I can turn this up to like three or so vs one on the 120. LOL
Half power is only a fraction less loud than the full. Speaker type and the number of them will make way more difference in volume.

FYI I like greenbacks but they are 25 watt rated. I am worried a pair of those would struggle with the 80 watt amp?
Keep in mind that "80 watts" is kinda subjective. That may have been what Orange claimed but It's two EL34s with plate voltages about the same as a 50 watt "JMP" type amp. I'd consider it ~50 watts.

I had mine tested (in 2 tube / 80w mode) by my old tech for output and it pushed about 110w cranked so it'll tear the ass out ofa pair of Greenbacks. Would not recommend.
Cranked will register more than the rated amount for sure. The way they rated these things back in the day, and the way we still use, is *clean* power. So turn the amp up till it breaks up, then measure and you'll get somewhere close to 50 watts. FWIW speakers are rated to match with amps, as well. So when Celestion says a Greenback is rated at 25 watts they mean it can go with a 25W amp, not that anything over 25W will kill the speaker. Its pretty fuzzy (no pun intended).
