That is the correct way to set the amp's carrier with the tuner on the back when using the stock driver tube. It's basically a JB 150 driving a pair of 3-500Zs.

Most of the originals were OMRON.
Some are...MHE402PG-UA-DC6 2A28VDC/120VAC
Another OMRON...MHE405PG-UA-DC6 5A28VDC/120VAC
Have also seen Magnecraft... W67CSX-6 NOM VOLTS:6 RES OHMS:52 CONT RATING:3A
Hope this helps,

I have used the 6LW6's to replace 8908's in a grid driven "modulator" type amplifier where the cathode and suppressor are both grounded. Output is lower though, usually about 2/3 to 3/4 of what the 8908's would do.

The 120 VAC could possibly be the contact rating. What is the coil resistance? If it is in the 100 to 180 ohm range then it is probably a 12 VDC coil.
