That's one of the very earliest units, most likely mid to late 2020. 300mA is not enough for the pedal to operate, it will need at least 500mA.Hey, y’all! I recently acquired this PA here at TB and I have a couple of questions:

why is this one blue instead of space-looking? Is it a first gen or something? Anything I should know about this gen?
more importantly - what power supply do you use and how many max milliamps of current do you have this pedal plugged into? I have plugged it into a 300ma slot on a rechargeable power supply and last time it went silent after a while. Then I switched to a separate 9v 500ma wall wart and it started working again. Not sure if it’s the load on the PS or just poor quality PS.
All that said some people still prefer the sound of the original "mini-tube" Particle Accelerator over the later 12AX7 version. Hope you enjoy it, and I'm happy to answer any other questions you have.
