THE GREAT MULLARD MAGIC BLOG — POLKINHORNE

These were selling like hot cakes in 1951 and details of their build and performance featured in much of the Mullard official literature of the time. Here we see Arnold Polkinhorne doing something with a Philips valve voltmeter.  Just look at that fat bottle EL37 lurking on the chassis as well as a stash of more MHSVT in the background. The fun cotinues as here is Dorothy Prinkle nimbly constructing and lacing a wiring loom for a MHSVT - looks like she's using the silicon covered wire display from Phil Marrison's BVWS stall - haha!
