mikee55 · 16th March 2006, 02:39 PM

I'm temporarily using a chip amp,since my main amp blew its output trannie.I am BLOWN away!IT came from a pair of Sony PC speakers,and put 7 watts up my 12" Goodmans drivers.(Mad).Anyhow,has anybody used a pair of back to back transformers as a cheap Isolation transformer?What did you use,and what improvements were made?
Please chat.
Thanks mikee55

You may be interested in this . Apparently it works very well.

If those are Goodmans 201 drivers that you have, they will repsond very well to being driven by a GC (mine run beautifully on 12 volt SMPS).
