So about the improvements:
The service increases the headroom of the unit, widens the frequency response, lowers the noise and increases the detail of the three dimensional image. Our primary goal is to turn this already good sounding dual channel tube preamp into a tube that professional studios and critics alike would reach for in thier mic pre aresenal. They are warm, robust and sonically excellent for Vocals, bass and any number of sources you would think to reach for this type of design.
We perform and number of mods on these units and gut the inside of these units so it is a lot of work, but the results are well worth it.
On these units we have modified the input, output and buffer stages with High performance Burr Brown opamps for optimum fidelity.
Coupling and de-coupling is also performed throughout the circuit using premium Pansonic parts for better frequency response, lower noise, longer life and more musicality.
The power supply is then modified for even better headroom and lower noise for the whole design.
New JJ Tesla tubes are then installed for a warm robust tube tone.
