What exactly is the Tube Pre / Tube Supply?
They are high-quality analog preamplifier systems from Pink Faun, with the Tube Pre handling signal amplification and the Tube Supply providing the power supply.
What types of Tube Pre/Supply versions are there (e.g., MK1, MK2)?
There are several versions, such as MK1 and MK2; the differences mainly lie in the circuit design, components (such as tubes), gain, and control options.
How do you adjust the volume on the Tube Pre?
This is usually done using a continuous-variable or stepped potentiometer on the front panel of the Tube Pre.
Is there an option to disable the tube section?
Yes, there is often a switch (“TUBES OFF”) that allows you to disable the preamp tubes so that only the line amplifier is used.
What inputs does the Tube Pre have?
Usually several line inputs (RCA) plus at least one input for a phono cartridge (MM, possibly MC depending on the version).
What types of outputs does the Tube Pre / Supply offer?
Standard RCA outputs to a power amplifier or active speakers; sometimes balanced outputs as well, depending on the model.
How do you connect the Tube Supply to the Tube Pre?
The Tube Supply is connected to the Pre via a multi-pin cable; all other connections (inputs/outputs) are made before the power supply is turned on.
Are the parts compatible across MK versions (tubes, power supply, chassis)?
Not entirely; some parts, such as pipes and chassis designs, differ between MK versions and are not readily interchangeable.
How long do the tubes need to warm up for optimal performance?
It usually takes about 2–5 minutes for the tubes to reach operating temperature and for the sound quality to fully come into its own.
What are the output impedance and signal level of the Tube Pre?
Typically, the output impedance is about 600 Ω and the maximum output level is around 6 Vrms in line-stage mode; different specifications apply for the phono input.
