I'm no expert on valves and have limited experience beyond restoring several Hacker Mayflowers, but I will say that the Mayflower uses a dual section 47uF smoother. Now the Mayflower has a 7 watt push-pull output stage. With that in mind, 47uF - while OK as far as the rectifier might be concerned - seems overly large for this tuner. I'd be inclined to agree with Keith's suggestion
It is surprising that no-one appears to have a schematic. Rogers were well-known and highly regarded, and plenty were sold. I've enjoyed viewing the pictures - it does seem to be a well-made unit. Interesting that they didn't simply buy-in a continental front end. Looking forward to hearing how this restoration goes...
