7G7 is the same as 1232. 7AG7 is a "preferred" substitute (lower heater current). The NJ7P site lists 7AH7, 7H7 and 7L7 as substitutes although the 7H7 is a semiremote-cutoff pentode instead of a sharp-cutoff pentode like the 1232.

The 7A7 is a remote-cutoff pentode.

I would stick with the 1232 or use a 7G7.
