For sale is my Eastern Electric MiniMax Phono
preamplifier.  It comes with the original
substantial factory packaging, manual, Baldwin-branded NOS 12AX7 tubes, and
heavy duty power cord.

I am the second owner, and the unit presents as new.  I am picky but can find no defects.  Build quality is substantial, weighing in at
a hefty 15 pounds.  This is a tube-rectified
design, using a 6X4 rectifier, with three 12AX7s in the output section (the
center tube sporting a metal RFI shield). 
Under the cover, it is a classic tube design: point-to-point wiring, ceramic
tube sockets (not plastic), and a choke in the power supply.  The front panel features only a power on/off
toggle switch, a blue LED power indicator, and a rotary play/mute switch.  The back panel has an IEC socket so you can
use your own power cord if you like, a grounding lug, a switch for either MM or
MC inputs, and three pairs of inputs. 
There is one pair of MM inputs and two MC inputs for high and low output
cartridges.  The MC inputs connect to the
expensive and rare Permalloy core step-up transformers used to increase the
voltage of low-output moving coil (MC) cartridges.  You have not heard great vinyl until you have
heard a MC cartridge into a high quality step up transformer into a tube
preamplifier!  Inputs and outputs are RCA

In January of this year, I had the preamp upgraded by Tom
Tutay, of Transitions Audio.  His power
supply modification is well known and highly regarded among Eastern Electric
phono owners.  He added much more energy
storage capacitance to the high voltage supply, replaced 2 diodes with superior
diodes, replaced the output coupling capacitors with a larger value, and
more.  The result is increased headroom and dynamics, and improved low
frequency extension and definition.  The cost for the Tutay modification was
$350 dollars. 

You can roll in your own preferred NOS 12AX7s and take the
performance up even further.  This is a
great sounding, highly regarded phono preamp period, and a giant killer at its
