Hi,

I have bi amped using a ST35 like tube amp for my Altec horns and a MOSFET amp for the bass. The sound was very good and the 15 watts was enough power for normal to loud listening.

I went back to my second MOSFET amp for the horns when one tube went out. I really can't say that I could tell any significant difference between the two. The tube amp may have been a bit smoother sounding but it is hard for me to say given that my hearing in the upper ranges is quite diminished.

At one time, I had a monster tape-playback system with 15 of them in it. A few of them went away when it was pulled from service, and I still have two ST35's use in various applications. They sound like most good tube amps of the time, and Dave Hafler's design was intelligent with the Williamson output. I would not hesitate to use them, or even the newer reproductions. Anything close to 15-Watts into an Altec horn will send your ears bleeding, so the power level is plenty.

Thanks guys for the feedback...I know 15 watts is more than suffice to run altec horns... I have a cheap Samson amp running them now and when the 2 watt light starts to blink its time to run

I use a pair of Quad II monoblocks into my 802's & I am very happy with the sound,much smoother than when I used passive crossovers.

Hi Dan;

The Quad II's I'm using are from late 50's,they use a pair of KT66 power tubes with a GZ34 rectifier & a pair of EF86 for the driver stage.
They produce aprox.18 watts & are dead quiet as far as any noise.
They sound great driving the 802's
I'm biamping & using a mosfet power amp for the 416-8B crossing over at 500 with a 12db octive slope. I don't have the specs but you could find them easily on the net.
