I'm seeking for a voice coil/diaphragm for a Altec 808-8B treble driver.
The one I have has an 8 Ohm VC and I would like to match it to my Leslie tube amp (16 Ohms). Could anyone sell one to me or name a source?

If you find that the 8 ohm diaphragmed driver is too loud, stick an 8 ohm resistor in front of the driver ( this will pad the level down some and help match the amplifiers output impedance better ) .Altec 808-8B 16 Ohm voice coil sought

Great Plains Audio is the source for current production Altec replacement diaphragms.
Also, the Radian 1228 aftermarket diaphragm for Altec drivers is available in 16 Ohms.
I'm not so sure. If he's using the original on the other side, current replacements will not match it.

- Personally, I'd put in a phenolic diaphragmed driver ( for the extra durability ) / ie; a JBL-2461 or JBL-2470 .
- Mind you, this Altec is what he appears to have on hand .

In what respect? The lead attachment? GPA sells the conversion kit, also. Radian as well, probably.
No Simbiotik anymore, but GPA makes a Pascalite equivalent for high-power installations:

Simbiotik diaphragms, a hybrid with a Kapton surround, as I recall, are no longer available.
The Radian diaphragms are similar hybrids.
GPA offers Pascalite, a different alloy than the standard aluminum, for use in high-power applications, instead....
