True; He was a Sound and TV studio engineer during the time I was growing up, but he had extensive knowledge of electronics so could have been a Field/OB engineer before that. Prior to joining the BBC (year?) he worked on the Taff Vale Railway (age 15), married (~1921), and became a regional sales-man/installer for gramophones in SW England and a violinist & cellist, as was his wife (Hilda Winifred Griffiths). I have photos of them with cellos. There are 1930's adverts for a shop in Plymouth that sold radios,etc, and the owner was a Phillips, but I've not found any details as to when it was started/closed but it's present use as a premises is well documented for recent years. Some newspaper clips suggest he/wife may have awarded Certs/medals at Music competitions in the SW around the 1930's, and he was charged with a "black-out" offence in the WW2 period and fined for showing a light.
