Safety

UK valve chassis: mains-derived HT rails stay charged after switch-off; original Hunts/TCC/Erie capacitors and the mains transformer are the two failure points. Value is set by untouched transformers and original cosmetics (silver/black livery), not by the valves fitted.

What moves the price

Sold-price aggregates are not collected yet, so the archive gives no figure — condition, originality of the transformers and a documented recap move this model more than any list price.
