Still need to take away a good 5 cm on the headshell, but at least now I can properly test it. That Acoustic 402 cab with JBL speakers will be the last cab I would ever sell
Performed the last modification. A red LED located inside the head shell between the screen HT supply and the screen grid resistors. Lights up when the standby switch is engaged and tubes are under voltage. Lights up stronger when the screens are drawing current. That's it, all done
One of the coolest features of the amp. The stereo jack socket with 1 ohm resistors, and the accessibility of the bias pot. Great for power tube rolling. Installed a pair of Philips metal base.
