what's the symptom? The 6561 was reliable enough. I can't remember
changing any in the '80s (but VIC-20s were already almost estinct when
I started repairing commodore stuff, so don't flame please).
As far as I remember, the 6561 was only used for the VIC-20.
Some IC traders might have them in stock, but I'd say it's a question
of luck to get good chips instead of bad/fakes nowadays.
I can help in troubleshooting your VIC-20 (as surely many others here)
if you're unsure.

Best regards
Frank
