Hello, this forum is extremely helpful.

I ordered a Maxon TBO-9 True Tube Booster and apparently it comes with its own/unique power supply called AC2009. Below is what the Maxon website states:

"The performance of the tube is kept stable and reliable thanks to Maxon’s unique heater inrush current control, which feeds the tube with a lower startup voltage to extend tube life. The complex multi-voltage operation of the TBO-9 prompted Maxon to develop a unique power supply for this model – The AC2009. The AC2009 provides very consistent high current that is regulated and filtered to provide stable, noise-free power to the TBO-9’s circuit. The AC2009 is auto-sensing, so it can be used anywhere in the world by simply changing out the detachable plug cord on the output side of the PSU."

And below are the specs of the Maxon TBO-9:

Input Impedance 500K Ohms
Output Impedance 10K Ohms or less
Maximum Gain 52 dB (1.6 KHz)
Equivalent Noise -110 dB or less (IHF-A)
Controls BOOST, DRIVE, TONE, LEVEL
Switch BYPASS/EFFECT (mechanical TBS)
In/Out INPUT, OUTPUT, INVERSE OUTPUT
Indicator BYPASS/EFFECT LED
Internal Circuit Voltage 30 VDC (DC-DC Converter)
Current Consumption 270 mA / 9 VDC
Dimensions 74 mm (W) x 124 mm (D) x 54 mm (H) / 2.9” (W) x 4.9” (D) x 2.13” (H)
Weight 560 g (excluding AC adaptor) / 19.75 Oz.
Power Supply Maxon AC2009 (no battery operation)
Accessory Maxon AC2009
Option Adaptor type (for foreign countries)

So now the questions. Would it be safe to power the Maxon TBO-9 with Pedal Power Digital or with one of the high current outputs with PP2+? Also, which cable would be necessary?

Thank you so much!

Yes. According to the TBO-9 specs, Pedal Power Digital 9VDC or Pedal Power 2 Plus high current 9VDC outputs will be able to power your TB0-9.
