The caps, resistors, tube sockets were replaced, but the circuit is original. I think this amp with the Heresys will make a good match - hope so.

Good choice! In fact, an opportunity... - CometCKO 18:34:46 02/27/07 (2)
I used my Dynaco for a brief while with Klipsch Cornwalls and liked the sound a lot. I think you'll be pleased! And you should never run out of amp headroom either, which is good for longevity of both amp and speakers.
In fact, you might think about wiring the amp in triode (or having your tech do it, if you're not comfortable doing the mod). It's about $2.00 in resistors and some wire, easily reversible if you don't like it. But I think you might.
Just my $.02

  You can check out posts on the Dynaco in triode mode in the Dynaco Doctor forum here on AA
  Here's a clip from that board:

  The triode mod is probably the simplest of them all without changing anything on the circuit board. All you have to do is place a 100 Ohm resistor between pin 3 and 4 of each output tube and remove the ultralinear taps. This allows the EL34 to run in triode mode instead of the stock ultralinear. Power output will be reduced by half and dynamics won't be as powerful but the mids really shine.

    I'll keep it in mind. Seems that the Dynacos are great for tweaking, but I haven't got it yet - want to see what it sounds like. It's already been tweaked by someone with much more experience than I. My guess is that it sounds pretty good as is. Later on though....
