They were good radios, they have two separate controls on the board for SSB Mic gain and AM Mic gain that allows setting the levels for each mode.
Meter backlights were green for rx, orange for TX and a red lamp for modulation and I cut the traces to the pll, used pull down resistors to protect the chip and controlled the pins with miniature toggle switches.
You had to be careful with the pll, even static can kill it if your not careful.
Had lots of fun with that radio.
