How long does Class A have?
Hi Guys/Gals
I have a Sugden A21SE which is a Pure Class A single ended design, I absolutely love this musical amplifier with its strangely plentiful 30wpc, it runs hots as they do, I always enjoy watching the faces of my uninitiated friends when they touch it after I mention they get hot, lol.
But in this modern green era I wonder just how long do Class A amplifiers have before Greta Thunberg gets wind of this inefficient method of creating sound and pisses on the parade?
Thoughts?

Why don’t manufacturers list the amount of amps (current) their amplifiers and receivers put out. It is nothing to do with watts. It all has to do about current. Why? if they can’t do it they will miss out on a sale. Listing the amount of current and watts and close to double into 8 then 4 and 2ohms, will give an indication if the amp can drive nasty loads, that so many of todays hiend speakers have. Not good for so many amps, Tube, Class-D and many Mosfet, have trouble into those speakers like Wilson Alexia 0.9ohm in the bass, your big BJT (Bi-Polar) output amps do well there Krell, Gryphon, Agostino, Mark Levinson etc etc Cheers George |
holmz As my amps run on 230v I guess they draw 1/2 the current and 1/2 the power?If your amp can run on 230V or 115V, it will consume the same amount of power on 230V or 115V. P = V x I That's why switch to 230V mains will draw 1/2 the current of 115V mains, and you need to install correct rating fuse accordingly for proper protection! http://pumred.fullrange.kr/2019/04/0416_parasound_hint_6_halo/0416_parasound_hint_6_halo_07.jpg |
