    Dynaco Mk IV's

    Were the Mk V1's a good amp?  They seem to be pretty rare.

    Think of them as a single channel St-70. Same everything in the circuit except the power transformer is smaller.

    Are you asking about the Mark 4 or the Mark 6?

    Indeed, I read the topic line and missed the "V1" in his question, which would be a "6", not a "4."

    Anyway, the Mark 6 (VI) was a 120 watt mono amp from Dynaco that used a 7199 input tube and a matched quad of 8417 output tubes, that were hard to find even when the Mark 6 was being manufactured.

    Never seen one in person, much less listened to one.

    I have a pair of near mint Mark VI's and 4 quads of NOS 8417's which cost me dearly...

    Dearly is putting it mildly. Even single tubes are what ... $85 for decent. Times 8 adds up quickly.

    Rumor has it you can convert the amps to use either EL34's or 6550's ...

    You can convert them for 6550's with some component changes but I opted to keep the circuit original. I have not used them yet but will do so when I redo my living room and connect them to my Klipsch speakers.

    I apologize for the mucked up title.  I was asking about the 6's.  Thanks for the pictures (gorgeous) they must be the Holy Grail of the Dynacos.  Were they offered as kits or were the all factory assembled?

    They were available as kits. I have two original, unbuilt kits.
