O2 Headphone Amp with agdr Booster Board

Jul 24, 2018
For sale, my O2 headphone amp with agdr Booster Board modification built and installed (see here for details). The O2 was bought as a kit from Head 'n' Hifi (see here for details) and built by me.

I'll try and dig out the original O2 op amps in case you wanted to revert the modification. Not sure why you would do that! Comes with original PSU.

All metalwork is silver. In excellent cosmetic condition and full working order.

Reason for sale? I have too many headphone amps and headphone amp projects on the go. :)

Looking for 100GBP. I'm based in the UK but would ship overseas if the buyer covered insured courier.
