Noticed in another thread an 8L is upcoming on the persons restoration list. Making separate post so more visible. The G228's have a 20 uF 50V electrolytic capacitor on them. I have had two short. When they short its a race between the trace on the board burning up or the backplane 30 AWG wirewrap wire burning up. One was on an 8/I I was restoring where the backplane wire providing the power burnt up at power on. Wasn't shorted before power on. The other was I saw one G228 had a burnt track while I was washing the cards in an 8/L. I had not applied power at that point so that was old damage. Usage history is unknown. As a minimum I would recommend applying current limited 30V to the capacitor on each card out of the machine before initial power on. Low enough limit may allow the capacitor to reform without shorting. The same part # capacitor is still available for protective replacement. The capacitors don't read shorted before power is applied. Unknown if they will short if the machine is powered on periodically. I've head lots of reports of all the failures in 8/L's. I replaced the one G228 and some bulbs but otherwise the machine was fine. It did need a lot of cleaning and I did do my normal power supply reform and checkout.
