I'll edit and update this entry as I go rather than continually add new posts

Information Resources:

the place I always start when I need info on valves is;

http://tdsl.duncanamps.com/ click on the software tab and you can download a personal copy of the search database to hold on your PC. Or use the online search, this (and the PC version)has links to data sheets.

http://hktubeaudio.homestead.com/ the Hong Kong Tube Audio Club - go to the main menu option & tube info for their tube shoot-outs.

http://www.jj-electronic.sk/ JJ valves home site

*A book worth reading "A Taste of Tubes"* Download or view from the link below

http://www.anthemav.com/OldSitev1/pdf/taste.pdf

Western Electric links - this link takes you into their archived tube spec sheets, but there are other interesting sections to go to as well

FAQ section from Vacuum Tube Valley

http://www.vacuumtube.com/FAQ1.htm

The Vacuum Tube Inc. "Hall of Shame" an article about some of the more common fakes and poor re-brands, some even perpetrated by the manufacturers themselves.

Weber Valve Bias Calculator

The BoatAnchorManual Archive

http://bama.sbc.edu/

It's big, it's American,it's flaky, it's got a strange name, but if you're looking for a manual on vintage Americana stuff, it the place to start, more odd manuals than you can shake a stick at! Patience and the refresh key are all you need (unless the file is in DjVu format, then you'll have to download the viewer - but its free). They also have a mirror site with all the same stuff again at;

http://bama.edebris.com/manuals/

Sellers WEB based:

http://www.tubetown.de good prices for new tubes (cheaper in many cases than the UK)reasonable postage, mainly a muso' site but still OK for audio stuff.

http://www.chelmervalve.co.uk/index.htm probably the biggest stock of NOS valves in the UK (least thats what they say)

http://www.tube-shop.com/uk/home.asp Every one's favourite? Well certainly not mine - totally useless, inefficient bunch who I've never managed to have one successful trouble free purchase from.

https://www.watfordvalves.com/order_frameset.htm Another of the usual suspects – watch out for that postal charge if you only want a single valve

Sellers eBay (that have provided good service):

big.daddy! (shop is 10x10 Electronics )

vintagelectron (US based, but I've had batches of tubes shipped over that have been cheaper than in the UK, even when you add in delivery and tax!)

tubeprofi (shop is TubeProfi Shopbased in Austria) usually good prices for new JJ's

Testers General Reading:

Good reading for testers in general, but especially for US ones

http://tone-lizard.com/tube-testers/

Testers, New Production:

http://www.amplitrex.com/the best looking high tech' one I've seen so far - no USB Connection though

http://www.hagtech.com/vacutrace.html

http://www.vacuumtube.com/toppage31.htm

http://www.transcendentsound.com/tube_analyzer.htm

http://www.britishaudio.co.uk/tubeimp.html

http://www.maximatcher.com/

Testers Old:

http://www.crowthornetubes.com/valvetest.htmusually has somethingof interest, but be careful and research before you buy.

Tutorial resources:

Download the Audio Classroom Series from AudioXpress

These Selected sections are very useful.

some more shops (based in europe andseemingly cheaper than the UK stockists). note that i've never tried them myself, just saw them listed on a zerogain thread:

http://www.audiotriodes.com

http://www.eurotubes.com

Eurotubes is a US company and distribute JJ tubes. But they are real enthusiasts and if you need to know how to bias your Fender/Marshall/.....then they have some nice little videos to watch :note:

bad service from http://www.hotrox.com

i ordered two sets of valves, both sets had faulty valves, they sent them in a jiffy bag,they denied it, i got the proof they did, both sets i sent back, second set i sent back they claimed they where ALL broken, had to claim off the post office, i lost £35 and no valves.

Wouldn`t recommend `em chaps.

Apart from the need for good packing and maybe insurance, are there any other problems with buying tubes from the States, ie.Import duty and stuff like that. Si.
