Default Spitsbergen Amp with PA630

Does anyone on this forum know anything about the Spitsbergen amp that used the PA630 current conveyor IC? (Come on Jan, I know that you're out there!)

In answer to some discussion in another thread, the PA630 was indeed patented (USA # 4,983,930) in 1991. (If you look that up, you'll find out who I am!) So, even though the circuitry was published in an IEE/IEEE textbook, it was patented, and it still is. It is licensed to Wadia and used in their high end CD players under the name "Swift Current".

Regards,

Linear
