Re: Attenuator - has anybody tested??
I may be in the minority, then - I swear by my hotplate. Does it color the sound a bit? Sure... Bt with the deep and bright switches engaged it's not too bad (with them off, though, anything over 8dB makes the amp sound horrible) at all, and more to the point, my Rectoverb combo running with the volume halfway up at -16db attenuation sounds WAY better than the amp with no attenuator does at the same volume.
And that's the critical thing to remember - yes, it's not perfectly transparent, but is your sound betterat the volumes you'll be using it with the Hot plate than without? For an amp as volume-sensitive as a Rectifier, I wouldn't recommend owning one in an apartment without an attenuator.
I wouldn't run the Triple wide open and use the attenuator to control the volume - with 6L6's, the "sweet spot" seems to be about halfway up with channel volume at around 1/3 on my Rectoverb, though with E34L's you can go a bit higher. Muchpast that sweet spot though, and you go from poweramp compression/coloration to poweramp distortion, and for high gain metal rhythm stuff you actually don't want a fully saturated power amp - the low end tightness just falls away. IT's perfectly safe for the poweramp and the attenuator to crank it all the way up, but I just doublt you'll like the sound.
I can't speak to how the Weber compares to the Hot Plate, bu I know a lot of guys over at sevenstring.org own and like Webers.
