Side contact, P8 valveholder would need AT LEAST 38mm diameter cutout, for the style valveholder shown.
I've never seen any other types for P-based valves (mind, I've not seen many anyway).
Mike - your post 25 about battery sizes, move from accumulators to dry batteries, etc is interesting!
For the record, I do have a post-war Pye 67a superhet, released 1946, it uses 2V Mazda octal valves, but probably one of the last designs to use the MO base. Which is a shame really, the large spigot did allow the exhaust tube to sit within the spigot, so the whole valve could be more squat, have shorter lead lengths, and work better at low-VHF.
My own Ever Ready ensemble is, a 5033 mains superhet (4V B4/B5 valves except tuning indicator which is a P; Ever Ready branded, and their own type numbers); a Model K (all-dry B7G superhet), and a Sky Monarch AM/FM (all-dry B7G superhet).
The Model K is indeed a good performer (it'll be performing after sending this post), agree with your earlier post about it being a good chassis Mike.
I'm interested in the 5214, when it's working fully on-song, and how it compares with the Model K - Mike, any comments here?
* Edit - I now see we both posted about the MO spacing units earlier, must've been within a few seconds of each other
