First off, your requet caught my eye as I'm looking for an audio amp that goes down to about 40Hz and hasthat kind of power. I'd use it for my bass guitar. They are easy to find. Any music store will sell you a 500W bass amp. What about using a very large 500W output transformer to impedence match a "normal" amp to the load. I'm thinking about tube amps that had an output impedance of about 1M ohm that used transformers to drive 8 ohm speakers. About a 100,000 to 1 ratio. You could salvage the transformer from an arc welder to re-purpose as your output transformer. These are designed for close to the specs youd need What are you driving? -- ===== Chris Albertson Redondo Beach, California _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
