Today I 'failed' the -12 V supply again and got screen captures of the TBoltMon GUI with the TBolt operating normally, -12V failed short and -12V failed open.
I used a 5372A referenced to a Z3816A to measure the 10 MHz output frequency of the TBolt for normal operation followed by -12V failed short then -12V failed open. It would appear that the DAC voltage displayed is unreliable/inaccurate when -12V fails. I would be happy to send them to anyone who wants them.
