I made one of these a couple of weeks ago , or should i say my version of one. It works a treat, the recommended Nuvo-Therm Tranny is silent and golden.
I haven't got round to posting my piccys on my webspace yet , but the project is really easy and cheap to acomplish. I have owned an MF X-PSU in the past ( about 10 months ago ) and sold it as the sonic benefits that it provides in no way justify the unbelievably high prices that it commands on the S/H market. I just couldn't afford to keep it given it's value and performance. I think there is one on e-pay right now that is upto £250 with days to go. My previous firsthand experience of this device ( as a critical owner/user) tells me that that auction is about £220 over budget !
DIY is the way to go with this one, although it probably won't look anywhere near as cute as the original, that ( the basic cast ali tube) was a design classic (imvho), that came out at just the right time.
