Here is the answer I received on the DIY forum. i spent ALOT of time looking this up! Someone else confirmed my finding. The INUKE 1000 DSP amp is $199. It looks like a good cheap fix to get the MFW running again.
Mark Seaton .... any thoughts? Thanks

My questions are:
1) Will the inuke 1000 DSP work for me? The stock sub has a 5.5 cubic foot box, it is ported, 15 inch driver (4 ohms). The original amp was 350 watts RMS. Sub is tuned at - 3 db @ 18 hertz. The stock sub could hit 120 decibels.
- is there a better amp you can recommend is this price range?
- Can I get the inuke 1000 NON dsp version instead? (its $50 less)
- what features do i need an amp to have? high pass filter? EQ?
2) I will connect the inuke to my receiver with a RCA to XLR connector. Then connect the inuke to the sub with a speakon adaptor & then bare speaker wire. Is this correct?
3) After I figure out # 1- # 3 I may decide to use REW. Can I use my analog radio shack sound level meter 33-4050 to hook up to my laptop (sound meter has a RCA out). Can I use my YPAO microphone from my Yamaha receiver? Or do I need to buy a digital mike to connect to my laptop?
Any advice you can give me would be great! THANKS!
1) Inuke1000DSP is a perfect match. The Inuke's will do the their full power bridged @ 4 ohms, in one channel.
Exactly what you said. I would keep the DSP version as that allows you to EQ your sub, and add a highpass filter, because your subwoofer is ported,
2) Correct, wire the speakon to the back of the amp, but don't forget to wire the AMP's speakon connector as +1 +2 if you plan on using the Inuke bridged. (+1 -1 normally)
3) You should be able to do exactly what you listed, but I have never tried it with my MCACC mic. Don't expect very much accuracy around 20hz with those microphones though.
If you don't want to do that, a calibrated Umik or Dayton umm-6 mic from cross-spectrum.com works.
