Two weeks ago he unveiled his latest find. Back in the 60's he knocked off the early Sunn amps using stock Mark IIIs in their bass rigs and made his own clone brand and actually produced several dozen units under his "Paragon" brand. He has retrieved two of them, Number One and Number Five. Basically a tone stack and a stock Mark III bolted into an amp head. One of the Mark IIIs has what he refers to as an original Dyna "potted" transformer, which is apparently quite rare in the Mark IIIs and superior in some ways? He opined that he believed Dyna started as a transformer manufacturer and went into amps but not sure about this, or the rarity/value of a potted tranny or if it even means anything or what the heck it is...anyone?? It seems to have a more rounded look no bolts or sharp edges.
I will get some photos for your review and interest but phone camera just did not do it justice. Historically I found it interesting that the Mark IIIs were well respected and were the basis for many of the relatively high power tube amps that were to come.
