Jeff Rowland Model 1

Good little amp get it, what Rowland was good at "linear amps", can "almost" do the wattage doubling act into each halving of impedance loading (below), would have to be BJT (bi-polar) output stage as complimentary Mosfets couldn’t do these figures.

Should be able to drive "hard to drive speakers" that aren’t too inefficient, like many of the mid/large sized Wilson or Martin Logans with their 1ohm loading or Maggies I noticed you talking about in other threads

Tested at
84W into 8 ohms
140W into 4 ohms
220W into 2 ohms.

I had one ( used it with a Rowland pre).. a little soft in the thighs.  I recommend using the balanced option.  Sounds like a good  find.

Get it if your speakers or system is already on the cool side.
The Model 1 and 2 are fantastic. They are a little on the warm sound side of the spectrum. I owned a Model 2 I still regret selling.

The "on" light on the button of these units tends to fail given their age. The parts should still be available from JRD and most qualified techs should be able to replace it easily enough.
