Ur fine.

I'm just trying to be careful my mentor from years ago always told me never go to high in capacitance when replacing electrolytics.

It is possible to raise the B+ in doing this, though generally not a problem. The other issue might be exceeding the rating on the rectifier for a first filter cap such as 10uf for an 80. In this case I would not anticipate any problems.

Depends where. If it's the first filter cap, the B+ will go up, though as Russ said it is not necessarily a problem. The second cap (usually after the field coil) it is not critical at all, wthin reason - the more the better (they probably would use more but at the time larger values were not as widely available).
RE: 10 mfd in place of a 6 - jake wells - 06-01-2019
Well since i read the schematic wrong and this is a 25-40 cycle not the 60 set the first cap is a 10 mfd and the audio is a 6 mfd. So a 10 will be fine.

Jake, your radio is “now” a 60 cycle set. Having said that, 10 uf will still be fine.

...by that, Steve means that your 50-A will now be operating on 60 cycle (60 Hz) AC. So don't stress it.

Sounds good i hope it likes a pair of 10/10 @ 450
