ThefrontpanelcontrolPCBchangedduringthelifeoftheamplifiers.
ThetwoPCBversionsareeasytoidentifywithoutdismantlingtheamplifier.Therotarycontrol
of the later version display PCB includes a push function, the earlier control PCB does not.
Operationoftheamplifierchangedslightlywiththeintroductionofthepushfunction.
In the event that a front panel control PCB requires replacement, the replacement PCB
suppliedwillbethesametypeastheoriginal.WhenorderingareplacementPCB,alwaysquote
theserialnumberoftheamplifierandstatewhethertherotarycontrolhasapushfunction.
NOTE: The two types of control PCB are not directly interchangeable. To replace an original
'non‐push'type PCBwiththelatertype'push'PCBwouldrequirechangesinothercircuitareas
andalsoupdateduserinstructions.
TheamplifieroperationalsoftwareislocatedonthefrontpanelcontrolPCB.

necessarytoprogramthePCBviatheamplifierprogrammingconnector.
