Hi

I wonder if anyone can point me to a web site that has a comprehensive
set of definitions of tube base types showing the dimensions (pin
numbers, length, diameter etc) and their accepted abbreviation (eg
B9A, Ct8, B9B etc).

I have a number of tubes where I find difficulty with base type
specification, especially those of WWII European military origin. Some
examples of tubes where I don't know the base type include AF100,
RGN564, LD1, LD2, VT4C, RG12D60 (all have different bases). Oddly
enough specs, pin outs and even photos of individual tube types can be
found but many base names and their accepted abbreviations are hard to
find.

I have searched many of the well known tube web sites, but those with
base details only carry a few common types, so I would suggest that
anyone who can help replies to the list as this could be of interest
to others.

Thanks Simon

Check out Franks Electron Tube Data at

http://www.mif.pg.gda.pl/homepages/frank/

you will find the AF100, LD1, LD2, VT4C (look under type 211), RG12D60.

RGN564 is a 4 volt filament tube and the equivalent is a Philips 1803
tube which does not help much

Hi Lionel and other respondents

Thanks for coming back, but I am afraid that I didn't make my request
clear. I have all the data I need on the INDIVIDUAL tubes listed, but
what I was looking for is details of the dimensions and official
abbreviation of the base/holder types that they use.

eg I know that the base type for a 12AX7 is a B9A and that for say a
6V6 is base type IO, or an 80 is a UX4.

I am searching for the base type codes and the dimensions for all
smaller tube bases or holders, especially European types.

eg what is the base type for a tube with 8 pegs, 4 on each side and a
diameter of 150mm (used for an AF100) -- is it a G8L, a G8A, 8AA or
what

It is the codes for the tube holder types that I am after, not specs
for the tubes thermselves which are easy to find, as you say.

I hope this clarifies the matter

Regards

Simon

For most American tubes, they are available in the RCA Tube Handbook.
Reprinted versions of these are available from Antique Electronics Supply.

European ones are harder, but the Telefunken handbook is a big help, and
turns up used occasionally. Also there is a book called the "Electron
Tube Vade Mecum" which is extremely useful for European types.

Hi Scott

Thanks for your comments, as you say US stuff is easily available, as
is UK info.

There are some excellent web sites giving tube data, both for specific
tubes and good generic stuff such as the coding built into various
manufacturers/country tube type numbers as well as factoy idents on
some tubes.

Looks like bases are too hard, but maybe some knowledgable person may
post something on the web one day.
