It’s fascinating to me to have first hand information about the radios and TV used in the USA. Many components used were introduced either at similar times or perhaps a little earlier in the USA such as silicon power rectifiers. Many circuit designs such as the totem pole power with the sound output valve, voltage doublers in the PSU did not get used in the UK, perhaps voltage doublers but rarely.
With electronics like other disciplines, there is more than one way to do a job, some due to contraints such as 117v power or just convention.
Thanks usradcoll for the info
