  Tube substitution chart on the Net?
Does anyone know of a comprehensive tube substitution chart on the web? I know there are all sorts of books one can buy, but I'm looking for the economy route first.

That's a great set of references! Thanks! I always wanted to get access to such info but really don't have a need right now hence didn't press the issue.
I have been reading many of your posts. Many times you sound anything but "clueless" such as in this post!!

Hey Thanks everybody. Glad you liked them and hope they are of some use.

Since you liked those I will add a little more. Here are a few sites on tube numbering, dates and codes which is always confusing.

Tube Numbering explained:

*) Åke’s Tube Numbering: w1.871
* Triode Electronics, Codes and Dates: www.triodeel
*) Tube Numbering Systems (Frank’s site) home.wxs
*) Philip, Valvo & Mullard Valve Coding: www.cs
*) Tube Numbering (MachMat’s Site): www.machmat
*) Russian encoding system: www.arrakis
*) Coding systems: www.arrakis
*) Brent Jessee’s Amperex, Mullard, Philips, Valvo tube codes: www.audiotubes
*) Phillips factory and tube codes: www.triodeel Note that all Philips subsidiary companies (Mullard, Valvo, etc) and all factories that made tubes under Philips license used these codes (Ei, Toshiba, Siemens, etc) so it's not limited to European Philips tubes.PDF file.

I remain
