Chet Posted August 12, 2019 Report Share Posted August 12, 2019 I have acquired a pair of AR LST speakers. The serial number is 00775 and it also shows under Acoustic Research Inc the number L-1672. I have being doing some research using your site but as yet can't absolutely identify how old these speakers are, can you help? Quote Link to comment Share on other sites More sharing options...
dxho Posted August 13, 2019 Report Share Posted August 13, 2019 They were made from ~'71-'76. Yours would appear to be early in that range. What requires knowing their age? Quote Link to comment Share on other sites More sharing options...
ra.ra Posted August 13, 2019 Report Share Posted August 13, 2019 Yep, early or mid 70's. But if you want more detail, many of the drivers from this era have parts number stickers with red ink on the backside near the terminals. The large type top number designates the specific driver, and below that will be a three digit and a four digit number - - - the four digit number indicates the week and year of that driver's assembly. And welcome to the forum. Since you are a new member with LST speakers, as part of your initiation routine, the traditional hazing ritual is for us to request pics and detailed description of your pair of speakers.

Chet Posted August 13, 2019 Author Report Share Posted August 13, 2019 Thanks for your replies. An elderly relative has died and I am clearing out their house. I will most likely be looking to sell these speakers so I was just wanting to gain more information about them. I am based in the UK and wonder if I should sell through a specialist hi-fi dealer or via the internet. Any advice welcome? Quote Link to comment Share on other sites More sharing options...

Extrapolating the dates of other LSTs; e.g., LST No. 00367 was built in August, 1972 and No. 00609 was built in December 1972, and AR was building around 60 per month during this period, on average. Therefore, I think 00775, an early style LST, was built in Cambridge around February 1973, just before AR moved from Cambridge to Norwood. The L-1672 is the tag publication number, I believe, but not the build number. --Tom Tyson Quote Link to comment Share on other sites More sharing options...

Chet, Those are in amazing condition considering their age. I don't know where you intend on selling them, but I would think they would fetch top dollar...er.... Euro...er pounds.... since they seem completely pristine. Good luck! --Tom Quote Link to comment Share on other sites More sharing options...
