Yes indeed a great article...
I grew up in NW Portland in the 60's-80's, I remember Sunn amps being used with local bands and every summer there was a festival at Wallace park where they would crank those babies and you would hear them for miles. Probably one of the first amps I ever recognized....
I then worked within blocks of where the old factory once built them in Tualatin...
Right now I own several Sorado's, 200S, Sentura II, Studio PA, Concert PA, Model T's, and acquiring my third Enforcer (would like to hear the real sory behind them), someday I hope to acquire 1200S as well.
It would be a pleasure to meet Conrad someday if I have the chance as I pass through West Linn regularly.
