Sigma made a 3-500Z amp in the late 70's/early 80's that was very well
done. They apparently did not import many to the states b/c you rarely
see them for sale. I had one about 15 yrs ago, the weak link was the
bandswitch. It was also an absolute nightmare to service.
Tokyo-Hy Power used to make a "HL2K" that ran a pair of 3-500Zs. It too
was very well done. Not very easy to service either.

Viewstar was Hammond and since they couldnt crack the US market they
approached B&W.
The Pi-L tank had a few problems causing lots of smoke and that was
redone.
Its the best of the 3-500 amps but its high price limited sales and it
was
discontinued.
