Not sure, you'd have to check the schematic, but I think the original power rectifier should be a 5Y3. The Rectifier tube in the picture looks like a 5U4GB, and the adapter looks good from here. I've done the same subbing a 5Y4 for the 5Y3. It should be OK, but the 5U4 generates a lot more heat.
Courage will follow when Faith takes the lead.
