Rock and Roll Combos and potted transformers

My interest and history with Dynakits is strictly in the rock and roll combo world. Started using Mark IIIs to run Voice of the Theaters many many years ago and the love story continues to this day. I am currently jamming with a friend who owns a recording studio in Omaha and he is also a collector of old stuff. You simply would not believe the tubes, offbeat stuff and oddballs he has from the combo period of the 60's and 70's.

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.

Sounds interesting ...

Potted transformer?

Looks logical....and similar in appearance to what I could see on the top end. Looks more like the trannys on my Citation II rather than the rather sharp angles and bolt through assembly on the Dynas. Was there ever a stock Dyna potted tranny supplied with the Mark IIIs? Was it better/superior? Rare or aftermarket?? Just wondering, no biggie.

Hi,
To the best of my knowledge...The Dynaco potted transformers were never offered with their kits, although
I do have a pair of Mark VI amps factory wired with both potted power & output transformers. They are difinetly Dynaco iron. When I got these they were wired for 100 vac. I suspect these were intended for Japan.

Additional taps allowed me to rewire these units for 120 vac.

What happens if you smoke a potted transformer? Do lizards come flying out of the refrigerator?

Can't remember. It was an hour ago. But we are straying dangerously close to thread-drift here.

I knew I was introducing a target rich environment here....and suspected who might be the ones to start the inevitable puns!
