You can, and I did but it ain't no walk in the park.
I did 20 years with NCR repairing computers down to the component level, so I'm a pretty good hand at soldering too,
but those relays were/are a real challenge.
You have to buy them in lots, I bought 10, used 2, sent some to onehundred80 and the rest to tighed1.
