Just received a ebay disk I ordered for "how to build a 4 pill amplifier" and after reading it I realized this is much more than I will ever use/need. It claims 1000 watts out at 80 watts peak in and 17 volts at 65 amps. Doesn't say if it is useable for ssb but has no switch for it just a power switch and a remote jack. I feel I could build this but just don't feel it is cost effective. This disk only works in a computer dvd and must be read and picture viewed one at a time, You can view pics in slide show but must read the instructions on how to build step by step. I paid $3.99 for the disk and $5 shipping only to find out that it is a burned disk and the envelope is marked $1.05 shipping. This was bought from bottinijohn on ebay. Just thought I would let you know in case you had looked at it. The info seems good but unsure about cost effective.
