This site offers freeware PC based test equipent such as a spectrum analyzer, oscilloscope, signal generator and frequency counter. It appears the author is an engineer at Sunfire and was part of Carver before that.

Nice stuff and the price is certainly right.

Thanks for posting that - have you tried any of the software?

On a totally different topic, I had not seen your site before and was intrigued by your SC150 amps.  It's the first DIY site I've seen featuring them.  I scratch built the Rozenblit T8 OTLs and love them, but a friend has rather inefficient speakers and has been looking for something that would provide 100W/channel.

Have you been satisfied with the SC150s, and would you recommend them?  What were your approximate costs to build them?

Cheers
