Yes, I see that one now from Max Gain Systems and I will order one when they open tomorrow. Earlier in my string I misspoke, my amplifier is actually twenty six months old, not six months old, and out of warranty. Sorry about the verbal typo.
Flashback: I think I know what caused the failure in the first place. I wanted to check the tuning on the amplifier before using it and hit the WSJT-X Tune button while the amplifer switched to the wrong band. There was a loud chattering of relays coming from the amplifier and the HF Autotuner which lasted several seconds. The amplifier went into error alarm and shut things down. The hf autotuner was not harmed but the amplifier's T/R relay must have welded closed its contacts.
OPERATOR ERROR 
Again, thanks one and all for your support.
The actual 12/26.5 vdc coil in the GH-1 is field replaceable. An open coil is extremely rare, never seen that happen...yet. In some applications, a 26.5 vdc coil needs to be replaced by a 12 vdc coil..and vice versa.
On sped up relays, typ an overvoltage and drop resistor is used. Engineers at Kilovac told me on the phone years ago, IF you are voltage limited, ( say 26.5 vdc is max u have to use), then switch to the 12 vdc coil. Then 26.5 vdc can be used (in conjunction with a drop resistor) to easily speed up a 12 vdc coil.
Or say all ur spare vac relays are 12 vdc coils....and u need a spare for a device that uses a 26.5 vdc coil (or vice versa).... then it's just a simple coil swap.
Note, although you can buy field replaceable 12/26.5 vdc coils for the GH-1, they are not compatible with the Kilovac HC1 / Jennings RJ1A. Dunno if the HC-1 coils are compatible with the RJ1A coils. Max gain systems carries both voltages, for all 3 x manufacturers.
Note, Jennings is now out of business, toast. Gone. Any Jenning's relay u come across is either old stock, or used, or NIB, etc.
