I am the proud new owner of the Dodd amplifier. Rich took great care in handling this transaction, thanks.
I have two 35AH batteries in parallel powering the amp at two 18AH batteries in parallel powering the preamp. These reside in battery boxes behind the chair in the photo.
The Dodds are running the GR-Research NS3S speakers which I believe are 92db sensitive and the 15 watts powers them to more than enough volume. I will be inserting a line level crossover at about 80-100hz to free up the base. The GR-Research sealed servo-woofers can more than handle bass up to 80-100hz.
If anyone knows the input impedance for the Dodd Amp please let me know as I need that spec. to build the crossover.
FYI, in the photo, the wrist band is a reminder for my wife to turn off the amp and preamp so that the batteries recharge (small price to pay for no AC line noise).
