Need Information On Valves

I need some info on valves types 6AN7, 68H5, 6M5, 6V4 and 6BD7. I
have one of each from an old radio I scrapped out for parts, and need
more information like type, function, pinout etc. All I know is that
they're 6 volt filament, miniature types. Not enough to be able to
use them in any future projects.

This site has some of these,

Are you sure that 68H5 isn't a 6BH5?

Might be. The writing was worn off the valve, I was looking at the
valve type label on the radio.

Yep, enter "tdsl search", which take you to the best valve data search
engine on the web, http://tdsl.duncanamps.com/tubesearch.php

** Thinking about that valve line- up again - you could make a nice sine
wave generator, going from say 10 Hz to 100 kHz. The two RF pentodes can
form the (Wien bridge) oscillator, with a dual gang radio tuning cap for
frequency, the 6V4 providing AC rectification and the 6M5 used as a cathode
follower for low Z output.

Maybe the 6BD7 can rectify the output signal and drive a moving coil level
meter.

Matter of fact - I have such an audio generator myself using a 6BE6, 6BA6,
6V4 and 6BQ5.

IIRC, 6BE6 is a pentagrid, generally used for mixers. What's it doing in an

** It may be triode connected, for low distortion. The original unit dates
from the mid 1960s - but has had several revisions and upgrades since
then. The dual tuning gang is turned by a 30:1 reduction worm gear, so has
near perfect resolution and re-settability.

The mechanical design part was done by technical staff at the Kodak plant in
Coburg, Melbourne.

Something like this maybe?

** That chassis and valve line up looks exactly like the one used in a large
HMV radiogram bought by my parents in around 1956.

It had a 4 speed Garrard auto-changer turntable with a Garrard / Ronette
crystal PU in a die cast tone arm !

Push pull 6M5s delivered about 8 watts into a 12 inch Rola 12H permanent
magnet speaker - all in an open backed, shiny rosewood cabinet.

What tone !!!!.
