echips are ok if socketed but most are socketed but have extra connections on because of faulty pins so they had to add extra circuits and trimmers to get them to spec
as a lot of the echips voltage reference was not to spec so they had to do these mods to get it with in the specified region
you will find on the ref333 boards that these mods are incorporated into the pcb and the chipas a lot of the echips voltage reference was not to spec so they had to do these mods to get it with in the specified region

and since you have two and one works, why not open them both, disconnect the power supply in each and with a VOM measure the Powersupply of the "bad" one against what the VOm shows for ther good one. It maybe that as you said, the problem is elsewhere but both power supplies maybe good. If so that would be useful to know in terms of parts. Lorne
