Here are some trace shots - sense tp low volt reg and reg board.
Looks like-50 and -5 looks bad on the low volt reg board.  Any suggestions?
In a good power supply will it power up with not being connected to main frame or go into burst mode due to no load?

Trusty 465 used - first tek I purchased in 1980.  Still going strong!
