Re: Fourier Components "Sans Pareil"??

Posted by Dr Legendre on October 21, 2004 at 15:01:34:
I can tell you beyond the shadow of a doubt, that none of the Fourier components were in any way designed by Ralph Karsten. However, when Fourier went out of business in the mid-90's, Atma-Sphere attempted to do service and support for their existing customers. One set was repaired.. but upon power-up a large, hi-voltage cap exploded and violently ejected itself from the chassis, leaving a dent in the Atma-ceiling. It was found that the cap, which was rated for some 340V, was being run significantly higher than that - either due to faulty design, or improperly selected components.
After these events, it was decided that the Fourier amps were far too problematic to deal with. If we could not offer a repair solution in good concience, then we just simply could not offer a repair. From that point, we declined to service any more Fourier equipment. To this day, all that remains is the dent.
