     Sorry, David, but I'm a little confused here, there was an implication that the set was a six-valver with two VP133's. If these were 2 IFamps, that suggests good gain and selectivity, if one was a tuned RF amp, it would fit in with the overall screening in keeping LO radiation down. Either way, it smacks of something a cut above the crowd.

     It was designed to spin to 20,000 rpm, but the inherent problems – and the enormous production costs – spelled the end for the seven-valver, and Yamaha embarked on a six-valve (three inlet, three exhaust) version that apparently addressed many of the concerns.
