Я бы уточнил:
Audio Dynamics Corporation (ADC) was a manufacturer of very high performance magnetic phono cartridges.
The company was founded by Peter Pritchard in the early 1960's. ADC was sold to BSR in the late 1970's.
Ну а БСР это британская фирма, не имеющего ничего общего с БСР Лимитед:
Birmingham Sound Reproducers BSR (Monarch); Great Britain bsr GB
Around 1970 was born also "Monarch" as an under brand.
In late 1970 BSR acquired by Peter Pritchard a new brand.. during 1975. No other notices of this new brand. Now is indicated as “A BSR Company” with a large availability of phono cartridges and replacements stylus for many type of cartridges.
BSR closed all divisions in 1985, then moved all offices to Hong Kong, as “Astec(BSR)”.
