Dynaco MK III Monobloc

Before Dyna, before Dynakit, the company manufactured transformers. They realized that between the Output and Power transformers they had most of the parts value of an amp. So, they put out the amp kits.

I think the 60 watt monoblock was over $120 when the rule of thumb was a dollar a watt.

I'd have to agree that $3K is high, for a pair of Dyna Mk III's. A really nice(operational and stock) pair, might bring around a grand on eBay. Matter of fact: (http://www.ebay.com/itm/Dynaco-MKIII-tube-amplifiers-pair-sequential-serial-numbers-s-n-tags-on-100-v-g-/110835587093?pt=Vintage_Electronics_R2&hash=item19ce50d815)

Wasn't the Mk III a 35 watter; sometimes referred to as half an ST70?

They can be wired to run in triode mode, and will do 30W. In pentode mode, they are rated 60W @ <1% THD / 50W @ <.5% THD. You may be thinking of the MK II(actually rated as a 50W amp, but did 35W @ .5% THD.

That's right; thanks. That's how my cousin used them; wired in triode. He drove a pair of Quad 57'S. I still remember that beautiful midrange.
