I am unsure which direction you are going, as the thread title and your last sentence seem to say opposite things.
Obviously you need to be able to supply the required heater current.
It is unlikely that a well-designed circuit for one of them will also be a well-designed circuit for the other, as the two valves have different characteristics. However, if you are not fussy about sound quality or the circuit is badly designed for the valve it has then a swap may be worth trying.

I am interested in this amplifier. But I just curious. Can I replace 6SN7 into this amp?

I bought many 6SN7s for my Cary AE1 project. However I want to purchase 300B integrated amp that I can utilized 6SN7s in my inventory.
I just found 1 product SSRP

However it is 6H9C. So it can't be replace. I have to find other.
