Anyone got ANY of the following:

Dimensions
It's same connector as B136, must be more than 202mm up to 340mm long, maybe same height & Depth (about 95mm to 102mm, likely not exactly square cross-section).
The B137 is a High Capacity B136, both "balanced" packs for 25mA filament valves.
AD3 is larger capacity and size, than the B103, and followed closely by the B136.
The B103 is for 50mA tubes, so older, but the Sky Emperor/BEREC Commander and possibly both versions of Sky Monarch (AM version adds 2nd DAF96, DL96 and DM70) use it though later 25mA tube sets as they have more tubes. The AD3 would also have been designed for 4 tube 50mA (250mA) radio unlike B136 and B137 designed for 4 tube 25mA (125mA). OP tubes take x2 current. There isn't much HT current difference maybe 8.5mA on later sets and 10mA to 12mA on early models.
There is an erroneous listing of AD3 as 102 x 191 x 51mm, but it's likely 143 x 283 x 70mm
The B136 is 200 x 102 x 92mm (fits properly in Sky Queen)
