This is info on the SRP31 and 31C, I don’t have under chassis layout information for the /D.

The differences described for the 31 and 31C are record deck and pickup cartridge.

The amplifier is identical using ELC83 valves in push pull.

The SRP31D with ECL86 valves has a similar upper chassis layout, I can’t confirm underside, be surprised if layout was a lot different.
