Hi Vinnie,
My 2 cents. 71A has a mu of 3. KISS rules on ALTECS !!! You can do a Direct Coupled tube amp, a simple two stage amp, if you use a mu of 70 or higher tube. I suggest mu of 100.
I would be able to send you a complete write up, on how to design and build such a circuit, just send me you email address. I've already done the write up.
Have fun with whatever you do !
Low powered tubes like the 71A require one to have great transfer efficiency, ( wiring ), inside the amp, to the speakers, and inside the speakers, to get the most of them. ALTECS are very sensitive to this !!
