On Sept. 9, the Beatles will release a 14-LP box set containing the mono mixes of many of their most beloved albums. We've teamed up with Diffuser.fm to give one lucky winner a copy of this excellent collection, 'The Beatles in Mono,' courtesy of Apple Records.

'The Beatles in Mono' includes the band's first 10 albums -- from 'Please Please Me' through 'The Beatles' -- and a three-record set of non-LP singles and B-sides entitled 'Mono Masters.' (For the Beatles' last two records, 'Abbey Road' and 'Let it Be,' they used identical mixes for both the mono and stereo versions.)

Housed in a 12" x 12" box, 'The Beatles in Mono' also contains a 108-page hardcover book with new essays, rare photos and a historical account of the mastering process. The mastering engineers cut the records without using any digital technology, and worked off the transfer notes written by the wizards who cut the original albums in the '60s. You can also purchase the box set at Amazon.

For your chance to win the 'The Beatles in Mono,' follow the instructions in the widget above. Sharing your entry via Twitter will give you more chances to win. The contest ends on Monday, Oct. 6, at 11:59PM Eastern. Be sure to read our official contest rules, and good luck!
