Title: I just saw the damndest thing... Post by: W7TFO on December 09, 2009, 04:21:52 PM Some guy was using a bank of 8 automotive ignition coils (like the one on your 65 Chevy ;D) as an output match from a single big pentode to a speaker. Seemed to work OK as an autoformer.
They were in a parafeed with a blocking cap arrangement. Bandwidth notwithstanding, this could be the answer to the shortage of cheap mod transformers, and would cut down on a lot of unnecessary driving in the neighborhood.... :-X Title: Re: I just saw the damndest thing...
