Certainly you should be using the correct power taps on the transformer for your local power (220V).

If you look at the data sheets for the two ECC tubes, you should be able to determine if they are interchangeable. At an initial glance, it looks like the operating requirements and pinouts are the same. I am no expert on this. You might want to give them a close look to confirm, and then give it a try - could be an easy solution. The ECC82 may have been used to effectively decrease the sensitivity of the amp, for whatever reason.
