    Recently dealt with Edicron for some replacement valves for my phono stage.

    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.

    http://www.vacuumtubesinc.com/Vacuum...llofShame.aspx

    Weber Valve Bias Calculator

    http://www.webervst.com/tubes/calcbias.htm

    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.html



    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.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.

    I really like this site as it has pretty pictures...

    This site also has nice pics. It's a shop but the link to the pics is on the left-hand menu.

    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:

    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.

    I've bought thousands of tubes from the states and I think I only ever lost one package and had a few damaged due to crap packaging.

    You may or may not get fleeced for duty (almost certainly if sending EMS [express mail] because it comes through Parcel Force).

    If shipping via normal USPS, chances are you'll get away with it. But...if it's insured, then the sender has to put the true value on, so it's more likely to get nabbed.

    Expect £4 handling fee (PO) or £13 (Parcel Force) + duty + VAT.

    Thanks for that. You don't happen to know what the rate of duty is do you? the valves themselves will cost around £95. Si.

    Not sure, I never managed to work that one out. I'm sure it's some complex formula or other. Way less that the VAT is the main bit...
