Where to get tube spec sheets, pinouts

[Zero Cool]

Looking for tube specs sheets for 6AS7-G, 12AU7, 6922 & 6CG7 tubes please if anyone has them on knows where i can find them.

Frank's tube data pages. Do a quick search, you'll find it. Pure gold.

See this page, download and install the TDSL-PE. It provides links to a lot of datasheets (Frank's tube data pages included). http://www.duncanamps.com/tdslpe/

"The TDSL (Tube Data Sheet Locator) Personal Edition provides information right on your PC for a large number of vacuum tubes.

Advanced searching facilities help you to compare different types and make substitutes for hard to find vacuum tubes.

It is intended to be of interest to amplifier technicians, amp modifiers, hobbyists and students. "

Here's a nice collection of links:

Frank's has s-loads of specs as downloadable *.pdf's. Those types are pretty common, so you'll probably find them there.

awesome thanks!!! Very cool websites!

I have searched, but cannot find data and curves for 6LW6.

Can anyone help?

Thanks

Here's a little bit of data:

Most people know that the 6LW6 is one of my favorite tubes, but I still don't have a data sheet for it. It is the octal version of the 6LF6. Some data is here:

Similar to (but higher dissipation) the 6LX6:

Also similar to 6MH6:

I have found at least 5 different constructions of 6LW6's. Some have "40 watt" plates with no extra radiating fins. Some have similar plates with fins welded to them. I have seen two different types of the "fins" on GE made tubes. Some Sylvanias have heat radiating fins, but they are different than the GE's. Due to an unfortunate drop test, I got to examine the insides of a GE 6LW6. It also had little fins welded to the inside of the plates.

The different flavors of 6LW6's do act somewhat different in linear operation, especially as the screen voltage approaches (or exceeds) the max spec. The bias voltage can vary by 50 volts (at the same plate voltage and current) from tube to tube. The finless versions should be kept under 40 watts dissipation, but the finned Sylvanias and GE's are cool at 60 watts, with glow appearing in the 75 to 90 watt region.

Last weeks experimentation had a Sylvania running at 80 watts for 2 hours with the screen grid at 500 volts. No visible glow from the grid or plate in a dark room.

Geek & Tibelab,

Many thanks for the information. Tubelab, it was of course your experiments that prompted my request.

I still like the look of the 6HV5 though!
