| The M73
is based on the coveted 1290 preamp circuit used in modules like the
1073, 1081,1084. They have an incredibly smooth character and just seem
to make everything you send thru them sound even better.
The M73 is
a dual channel, three stage, all discrete, Class A, transformer
coupled preamp. The M73
utilizes an all discrete transistor design and offers a Direct Input on
both channels as well as Phantom, Phase, Pad and Impedance switching.
The three stages of amplification provide the user with 80 db of gain
output via a Grayhill stepped attenuator. The M73 also offers
an impedance switch at the microphone input between 300 ohms and
1.2k. The higher
impedance is really nice for Ribbon microphones but works well as a
color option as well. We use Carnhill UK transformers to keep the
sounds as close as is possible to the original.
These beautiful Dual
Channel Class A Hot Rod preamps are handmade here in our shop in
the USA and are completely hand wired like all of our models.

My parents taught me
to invest my money wisely and that I
shouldn't simply be buying something, I should be investing in
something. As my
dad was heard to say after a long debate over the new fridge " I only
want to buy this fridge once!"
understand that Audio is your business and is an investment. I have
designed all of our preamps and compressors not only to sound second to
none but to last for years and years to come.
