If anyone wants to try a supply with an active second stage rather than the passive filters in those things, just let me know.

Some of the options seem insane as well. For example: http://www.townshendaudio.com/hi-fi-home-cinema-equipment-vibration-isolation/hi-fi-home-cinema-vibration-isolation-equipment-stand-rack/ Well, it may be valid to question Max's sanity, but I dont see why you point those supports out as insane. ...

The safety standard is covered in IEC 60065:2014 Audio, video and similar electronic apparatus - Safety requirements

Exposed valves also fail on the temperature front.

If you want real thermionic street cred a scope clock takes a lot of beating.

You make valve gear, you know perfectly well if you sent any of it to a test house it would amost certainly fail as would over 90% of valve gear, if not 100%. The product in question that passed third party safely and emission regs is a valve based two box phono stage, so I can't agree with you the...

AND will it all become redundant when we say FECK YOU to the EU daft regs along with the EU itself and sell most to the US and the far east :think: Well, in general, I didnt see any reg in there that I would call daft, they were all based on the idea of not killing your customer. Most are based on ...

Not sure 'everything' from China is cheap crap, but I take your point. £7k to certify for CE is a pain though... No, my aim with these is to...

may well cost a couple of grand to make (can it cost more?), but the case and meaty transformer will account for most of this cost I reckon. I would check the price of good quality electrolytic caps as well. And lets make a guess and say it takes a day to build. So thats one persons wage for a day....
