[ICOM] IC-756Pro Linear amp SEND relay kaput

[Dave_G4GED]

Hi Guys
Looks like I've  just "blown" the non-Icom Linear amp control SEND relay 
contacts, (max 16V).
This port's now stuck to ground, permanently "ON" tx.
Seems my own fault for carelessly connecting it for a few moments to my 
TL922 that has +100v RL control line. (Altho' you'd think this facility 
could be made more versatile & robust.)
Wonder if anyone knows how to go about fixing this fault or is it a job for 
the Icom workshops?
Mni tnx in advance for any help
