[Collins] 30S-1 problem

[HENRY LEWIS]

Help please!  Recently when operating with my 30S-1, on releasing the PTT
the amplifier hangs in transmit mode for a further 1-5 seconds.  This makes
it unusable, especially in pileups.  The problem is definitely with the
amplifier and not the exciter, as shorting the relay input on the back panel
produces the same effect.

Looking at the circuit, it seems to me that maybe relay K101 is actually
sticking, or perhaps it could be held on by a leaking C212.  I can't see any
other potential reason.

Has anyone else experienced this?  I would appreciate some advice.
