    I have the following data on the Altec 1570A: circa 1954; 165 watts at 3%
from 70-20,000 cycles; " The 1570A utilizes only 2 tubes in the output stage,
and they are the reliable 811A triode transmitter type rather than the light
weight push-pull-parallel  receiving tubes found in other power amplifiers. A
design which includes only 10 vauum tubes eliminates the heat problem  caused
by other amplifiers which require from 20 to 48 (sic) tubes to do the same
job." cost: $297.
 
     I assume the 1570B is merely a refinement of the above. It appears to be a
theater amp, but of high quality for its era. Mono, of course.
