    The little Virtue ONE.2 looks like a real bargain, has the same chipset as the M901?

    I recently picked up a Virtue one.2 second hand from someone who had already shipped it over to Europe. It's got the upgraded power supply they sell. Really an impressive little amp, so far. I do believe it has the same chipset as the Sensation. It's exceedingly easy to bypass the volume pot, which results in a more forward, immediate sound. I'll also be swapping out the capacitors to get closer to the Sensation's specs. The other differences being more inputs and copper posts (as well as the really tempting tube buffer option).

    I'm still burning in a hlly tamp-90 that had a horrendously long stay in French customs before I give the two (destined to different set-ups) a comparison.

    Be interesting to read your impressions. I used to have a 90. Nice little amp.

    No, the PSU can't supply enough current It might well turn on & work at very low volume, but as soon as you start turning it up the PSU will go into current limit & the voltage will drop like a lead balloon

    12v 500A
    I could have sworn that said 12V 500mA a minute ago?

    Yes, only has a quarter of the required current. You could try it the other way round though, to see if there is any improvement on the Cambridge.

    Yeah, it's a no go i'm afraid - too little current output

    Hi There, I also have a Mini-T, but with the 12v 5A SMPS, additionally I have a Muse M21 EX T-Amp, for which I bought an upgraded 60W linear PSU, which makes a massive difference to the Muse...

    http://cgi.ebay.com/ws/eBayISAPI.dll...#ht_2362wt_812

    ...however it has only just returned from repair (as of 25mins ago), I started a thread on the repair in the DIY section about 5 weeks ago if you want to check it out. Mark et al were very helpful in the problem resolution...thanks again guys it's sounding very good again.

    So buyer beware!!!

    I'll try it with the Mini-T when I can check out the polarity in better light, out of interest has your Mini-T got an adapter on the amp end of the power lead? I've just noticed mine has, which can't help...
    Cheers, Will
