Well, the parts arrived today, but just barely intact. Box was crunched and split open along one long side. It all appears to be there though, so it's a testament to Joe's packing that it all stayed in the box. I'm doing the conversion first leaving the O/P stage Quasi Complimentary. Will do some listening tests and then convert the beast to Full Complimentary. I will be using the new chassis and the back plane boards when I go that route. Joe said the old 700 Transformer will fit the new chassis, I assume the front panel holes will also line up with the old style front. If not I have adjusters here.
On another note I read somewhere about some one putting this amp back into production and such. Has anyone here ever considered building this as The Super 700M? Using a toroid power transformer and an air tunnel for cooling? This thing sure produces gobs of power once converted, is way under heat sinked but may be able to produce even more power if built as mono blocks with a slightly larger transformer. I'm thinking 2kva on the toroid for each mono amp, I'm estimating the original transformer taking it's lower efficiency into account at not more than 1.2 to 1.5 KVA. In the early 70's BGW produced the Model 1000 power amp that you could actually arc weld with. Needless to say they nicknamed it The Arc Welders Special. I worked with some of these amplifiers for Sensurround way back and they were extremely powerful. Anyway, I have cloned Krell's and many other power amplifiers and line stages over the years, so the thought of a WOPL Super 700M sort of popped into my mind.
The 700 amp picture is mine as received. The unit actually cleaned up almost like new.
