Illuminati (2nd Degree)

Hey-Hey!!!,
ON the peanut tubes, the 5687 is the same size as an AU7/AT7/AX7 ( heh-heh-heh...).

There is one more thing y'all may want to do. Prepare for adding a second 9-pin socket so that you can run the 12B4 with its lower gain.

The mods are simple: 6 LED's instead of two.

and of course the second socket. Heater current for two at 12.6 is .6A instead of .45 for the 5687. Minor tweaks of the supply *MIGHT* be required if you want to hit the heater voltage +/- 1%
regards,
Douglas
