Theses never shipped with P1 tubes that I know of. This set is the only application of the 3KP4 AFAIK so there weren't tons of replacements laying around even back then. The TV37 was the cheapest pre-built TV on the market when it was sold and had the smallest screen you could get...Short of portable applications that set probably wasn't desirable enough to put a CRT in once it was 5 years old.
I also have seen first hand a power rectifiers tube in one of these sets fail and pop the CRT heater... I'm just glad it wasn't my set.
