  • 12" flat faced circular CRT, 405 lines (system A) b/w TV with 5 channels VHF (Band I only as it's before 1955) tuner.

    The T.1125 is the console version. They are almost identical electrically and mechanically identical with the T.1215 and T.1415 (more detailed description in R&TVS). Unusually for Line Flyback derived EHT of this era these are AC only models, the T.1825 and T.1325 are almost indentical but AC or DC operation and PZ30 instead of Metal Rectifier, they are identical in appearance. The T.1225 is also very similar and the T.14T2 differs only in having a 14" Aluminised Rectangular CRT

    R&TVS don't list CRT type but it's focused by an adjustable permanent magnet

    About 2.7MHz to 3MHz Video IF bandwidth (Sound IF is 3.5MHz above Vision carrier IF)

    Warning Live Chassis. A Mains plug wire connected direct to Chassis. Aerial isolation capacitors should be safety types.
