Vacuum Tube Equipment By Greg Sage
Vacuum Tube Limiter
Designed with a solid state side chain inside of a tube input-output stage.
This allows for very fast attack-release times and a wide range of ratio.
Also has a solid state meter driver.
This design has 4 separate highly regulated power supplies,
also with soft-start tube heater circuits.
Vacuum Tube Compressor
This design uses an optical circuit in a tube feedback loop to give very high squashing abilities.
It incorporates attack, release and scale along with a tube input-output stage.
This design has 4 separate highly regulated power supplies,
also with soft-start tube heater circuits.
Vacuum Tube Direct Box
In 1980 I started working on a DI design using a tube for the input stage.
The tube gives a very high input impedance, around (10 meg ohm) that wont
load down guitar or bass pickups like traditional transformer based DI boxes did.
The tubes output stage was paired with a high quality balanced Jensen transformer.
Vacuum Tube Mic Preamp
Dual channel tube mic pre’s with phantom power.
This design features dual variable gain stages (inside feedback loops).
This approach is unconventional, but I never liked the sound of input pads.
Variable gain stages removes the need for input pads and keeps the source sounding very open.
Input pads always sounded to me like a someone put pillow over the mic.
This preamp design has both high and low output gain stages.
The design has 3 separate highly regulated power supplies,
also with soft-start tube heater circuits.
Vacuum Tube Mic Preamp
Single channel tube mic preamp with phantom power.
Designed with a single variable gain stage with lower gain amplification.
Many of my mic preamps are low gain stages, which is all that is needed
for recording drums, guitars and some vocals.
This allows the tube circuit to run open in it’s optimum operational range
without padding it back.
This gives a very open, fast response sound.
This preamp design has 3 separate highly regulated power supplies,
also a manual soft-start tube heater circuit.
