Hello Sammy

The answers are here

PThe PB-010AA Chassis was the First Cobra 148 GTL-DX MK2 version produced. There are a few notible differences between the AA and AB Chassis. The below picture is of a 010AA Chassis, notice how the 3 tuning pots VR3, VR4 & VR6 are all orientated the same way round.

The mkII has the PB-010 . The Superstar 360s I have allhave the AB variant and I was just wondering what the difference was between them .

The front of the board differs slightly from AA to AB, IE: Beep circuit but apart from that not much else at all.

I have seen a few AB's where both sets of crystals are present with 6 tuning inductors, But not for a long time.

Then its being switched wrong, I have seen it done before in the PC-879AB where one leg of TR33 is switched to ground which only mutes the beep tone, Simply switching the one leg of C146 [beep timer] will knock the beep off completely with no delay.
