The Satchmo is a very high quality preamplifier that uses an SRPP driver stage. It is designed to compete with the very best. The circuit design incorporates a high voltage regulator that keeps the voltage to the anodes at the optimum value. DC filament power helps to create an amplifier with low noise and exceptional sonic qualities.
Specifications for all Satchmo Preamplifiers are:
Frequency response 15 HZ to past 25 K HZ +/- .5db
At 1 volt into a 50K ohm load.
S/N in excess of 90 db at 1 volt.
THD under 0.5% at any frequency.
Maximum output into 50K ohms in excess of 20 volts.
The Satchmo can be designed and built to your very own specification. Options include:
your choice of attenuator
number of inputs /outputs
There are various levels of phono stage available and these can also be produced as stand alone units starting at £500.
All Satchmos are hand built using point to point wiring with silver wire in the signal path, Kiwame carbon film resistors, LeClanche or Mundorf coupling capacitors, and JJ802s valves.
The base model with Alps volume control, two outputs and four inputs built in the customised Italian case in the photo costs £1,100
