Question re TL 922 amplifier

Dear All,

My kenwood TL922 has developed a strange fault.  When I switch it on (via
an 
Ameritron Soft Start module) I get a negative reading on the Ig meter 
of -50mA and a positive reading of around +100mA on the Ip meter with no
key 
down.

Keying the amp has no effect and the relay does not energise.  I have 
checked the ALC and relay connectors and the coaxial cables

I've tried starting it directly bypassing the soft start box and this has 
made no difference.   Obviously I do not leave it on for more than a few 
seconds as there is clearly a fault.  I have had the covers off and can
see 
nothing untoward in terms of burnt components and there is no burning
smell 
and the fuses don't blow.  Also both valves (3-500zs) light up.

Any suggestions as to what may be up before a trip over to Castle, has 
anyone else seen similar

thanks
