Info sources for DIY tube amp build

[Twigman]

I have been toying with the idea of getting an all valve head.

I have toyed with the idea of giving Matamp a ring and dropping £1.5k on a GT200....but it feels like a lot of moolah.

Then I thought i I could make my own, <Top gear>[i]How hard[/i] [i]can it be?[/i]</Top Gear>

So I started to trawl the interweb looking for info.
There does not seem to be much out there.

So....what info sources do you suggest for a DIY 150-200W all valve bass amp potential build?

I'd ideally need circuit diags, parts suppliers, costings etc etc

Some of his text is a bit suspect (he refers to the tone control inductor in the SVT as a 'transducer' among other nonsciences) but it's full of schematics.

For top quality iron you could go to http://www.sowter.co.uk/

and for glass envelopes of vacuum: http://www.thetubestore.com/

Everything else you should be able to get from Farnell.

Much better off buying a fixer old amp and rebuilding it. Old PA or something, the layouts on the Mhuss Hiwatt site are probably the most useful thing as a build resource.
