I recently emigrated to the US and needed to get a 120v power supply for my old amp. None were available – MF stopped stocking them a long time ago and I couldn’t find one one ebay or any of the other usual suspects.
I found John through an audio forum and contacted him – I thought I would take the opportunity to get the amp and DAC refurbed and John also exchanged my power supply for a US voltage one.
Having listened to the amp again – wow – crystalline clarity, great presence – lovely sound.
Would recommend to anyone. Very nice chap too.
