[Amps] How to Bypass TR circuitry in Alpha 86

[Mark - N5OT]

Hello Power People,

I have an Alpha 86 where something has failed resulting in a fault.  
Since this failure mode began very shortly after the amp received the 
newer and stouter PIN diodes, and the amp was not subjected to excessive 
abuse, I believe the control circuitry itself may be wonky. I would like 
to take my chances, bypass the internal TR circuitry and also the 
control circuitry, and use an external TR switch I have on the shelf 
(Ameritron QSK-5).

Unfortunately 100% of the time at the first dit the control circuitry 
bounces the amp out of transmit mode rendering it unusable.  I would 
like it to stop doing that.  I fully understand the risks and am willing 
to take them.

Suggestions?
