Bryston serial codes-how do you get date?

Know I got an email fom a prspective seller but unfotuntely didn't write it down nefore the email got deleted.If amybody can help me out be apprecited.Was really looking for an 4B ST but fellow who gave me info was early in bidding on Ebay with a B60 and I think it had not only the serial code but also adate code stickermaking it a snap.I am getting impressionm that folks are spending same amount on Brystons that is 16 years old verus one that is 4 years old which any small updated to cicutry before new series seesm to not make sense just because well one if practically new the other is at the end of many amps life spans.Not sure if the ST's will last 25,35.or 50 years (certainly they are better built since 20 years when it comes to amps is end of life of the average Bear.But want to know what I am looking at if serial is given.Checked Bryston site and it wasn't much help beyond touting 20 years.
Much thanks

I have a 4B-ST, but I can't remember if the date of manufacture is part of the serial number or is a separate date code on the unit. What I do know is that Bryston was very helpful via email when I had questions. I emailed them several times asking about the age and repair history of various used Bryston amps and they always responded within 24 hours.

Send them an email - I am confident that they will answer your questions.

You will need to brush up on the pythagorean theorum, and have a slide rule to calculate the date!

I just sold a 4B THX through Audiogon last weekend. While my ad was posted a bunch of people asked about the serial number and build date so I e-mailed Bryston. They didn't give me an exact build date, but they did narrow it down to within two years.
