I bought one of these little beauties from one of the troops a couple of weeks ago www.ebay.co.uk/itm/25VA-24V-Hifi-linear-power-supply-amp-DAC-external-PSU-with-display-/111591718795?pt=LH_DefaultDomain_3&hash=item19fb627f8b and I'm using it ( set at 13.5 V ) with my Amptastic Mini-1 . This little Chinese PSU is an audible improvement compared to the one which is supplied with the Mini-1 .
For some reason the seller doesn't inform prospective buyers that the voltage of these PSUs are adjustable . I had a play this morning and was able to adjust the output on mine down to 5V and up to 24V . So it seems that they can be used with a variety of kit . Furthermore it's a 20 minute job at most .
The adjustment is made via a little brass screw to the rear of the transformer . Sorry , but I'm not an electronics engineer ( nor a photographer for that matter
) so I don't know what parts are called ,and it requires the minimum of tools , a Philips screwdriver , a little flat headed screwdriver , and an Allen key ( £1 shop specials )
The DC cable can also be improved making another audible upgrade .
