Tube amp for a somewhat difficult load

There is a product called the Zero Autoformer that I recommend you investigate along with your amplifier search. You can find information regarding these at the following link. http://www.condor-connection.org/asog/tweaks/ps/index.html

My speakers are rated as a nominal 8 ohm impedance and benefited dramatically by using the 2X setting of the autoformer.

I do not use any speaker cable, just the Zero's, with my monoblock amplifiers. They are a truly tremendous product.

i have a little tube research 80 watts triode . it has a larger power supply than audio research 600s . it will drive the hales like no tomorrow. where are you ? i will show you.

I own the Tube Research Mono 100's, (Less than 100 watts in Triode pair of KT-88's, I can tell you that they can drive a difficult load easily. You may wish to take Kirk up on his offer.

atma-spheres ,jadis ,vac,wolcot, sonic frontiers, conrad, etc; all these amps are worth a try. they are all damn good amps. i have owned jadis 200 monos ,conrad premier 11 ,12s and 8s, sonic frontiers power 3s. on and on. i would of been happy with any of them if i had not heard tube research. i use to enjoy trading amps preamps etc. now tube research has ended my trading , buying selling . i now trade buy and sell with secondary systems only.
