if it is any help, the schematics except the antenna coil are virtually identical between yours and mine AH-162. They even kept the part numbering close.
So, the set is simplistic, easy to align and quick to recap.
When re-capping, make sure you make C3, the antenna cap, 2nF 600V at least or better yet a Y-type 2nF.
Also C14 should be X-rated line filter cap, any rating used for 110V AC line.
Other caps do not have to be rated as they shown, 400V or even 600V - they simply used what was available. 250V rating is just fine across the whole radio.
Oh...don't be surprised if you find out that many caps are not of the value that they are shown to be in the sch. Emerson as I understood was known for doing that. I guess it did not even matter much. I found probably half my caps being different to the extent of an order of magnitude.
