Almost all UK TVs used series-string heaters. Normally
P-series valves (P
= 300mA heater), or their equivalents (such as the Mazda 30xx series (30,
again, meaning 300mA).
Some of the ones I remember in that Ekco were definitely in the 30 prefix
series -- pretty much unknown here- but there were P series (well known
here) equivalents or near equivalents, needing only one or two base wiring
changes!!
Loved the OT tube/valve list- lotsa memories- and not all bad!!
