Amplifier kits x 3
« on: June 11, 2018, 06:03:05 PM »
I am dismantling and selling the parts of my Naked amplifier.
The sale of the parts are conditional to ALL the parts being sold and paid in full.
The amps are really great sounding and very powerful. I have no need for such a powerful tri-amp anymore. Now using a 7 Watt amp.
