DW505 type 3: What is the resistance specification for armature opposing pole pairs? Also, isn't each pair supposed to be isolated from the other?
Measuring across the commutator opposites is a rough check - if each pair has the same resistance it is probably good but even then there are no guarantees. I have never seen the armature resistance stated for any motor though that doesn't mean such figures don't exist.
It would seem logical that each pair should be isolated but that generally is not how the armature is wired and each commutator segment is the termination of two coils.
In reality there is only three ways to test an armature - either build it into a motor and see if it performs ok, use an automated motor fault analysis machine or one of the dedicated armature testers such as an armature growler.

Need a schematic for a victrola radio model vta 750
The fashion for nostalgia radio with a modern sound has brought about a clutch of models from only a few manufacturers.
I have only encountered one such that was basically an in-house cabinet with bought in internals, the quality of which was probably reflected in the price and as this was from the lower price bracket the internals were from different sources and badly matched.
I know of no reason to assume other models would be substantially different because although popular they haven't sold in the high numbers that would justify purpose built internals and so the chances are an experienced audio engineer would probably recognise the circuit board as being from a popular hi-fi and be able to provide you with details.
