This showed up last week at a local Auction place, the inspection and auction was today and I snagged it for a C note (+ 13% buyers fee and taxes).

I believe it's a BV20C based on the information found here:
http://www.thevalvepage.com/tv/pye/bv20c/bv20c.htm

It seems to be complete and in good shape, other than the CRT cup is broken
(I was nervous as hell they would neck it before I got it) and it's missing those Bakelite rings mentioned on that page.

This thing is tiny and light, Smaller than an Admiral Bakelite console, Lighter than a GE Locomotive! I carried it the 100 feet to my truck with little effort.
It has four casters on the bottom that appear to be OEM.

These late 40's British sets look a lot more Pre-War than their American counterparts.

The CRT has a Loctal base, not sure how to test it, would an adapter on the B&K using the 10BP4 settings work?

Of course it's also runs on 210-250 volts AC/DC so I'll need a step up transformer (but not a Variac :D )
Does anyone know if this is a flyback HV system or "Brute Force"?

The Red things are apparently EF50 tubes, not capacitors.

6.5KV? It's a safe bet this one is a widow maker. ETA: WAIT--If it's AC/DC, then it can't be "mains-derived EHT" because you can't step up DC with a transformer. d'oh! :twak: And yeah, an EF50 is kind of like a British 6AC7. Loktal base on those too, istr.

I've restored a 1956 model PYE but it is obviously nothing like yours. What is that big lug sticking out of the top of the CRT bell? As far as the EHT system goes you'll have to remove the big round cover to reveal what's inside. That set would have to be very rare I reckon. Hope the CRT is o/k.

The lug sticking out is the evacuation nipple, it has a rubber cushion on it to protect it.

The only post war American CRT I've seen with that feature is the 12WP4 used in a couple Philco Models in 1951.

I don't have an adapter to check the CRT but the heater works.

Very nice!!!

Perhaps start a thread here to get plenty of advise on the set
