Vacuum Tube - 6L6GC, JJ Electronics

I've got a Krank Rev Jr20, came with 5881 from the Krank Factory, when I bought it secondhand it had a busted GT-6V6-R tube, looking to replace them, would the JJ-6L6GC work? If not what tube would yall recommend? This amp is "cathode bias/non adjustable" Thank You, Tony

6L6 tubes are interchangeable with 5881s, but a 6V6 is not compatible with the two.
