dr5chrome Posted April 5, 2020 Report Share Posted April 5, 2020 Hello - New to posting on this forum, but a minidisc user for years. Anyway, I haven't been too active the past 4 years or so on my system, which includes the 940. I see the 940s have skyrocketed in value. I thought I would pick up a 2nd unit as a backup because I believe mine is having an issue with the drive unit. Its glitchy. Given the increased prices for another unit I thought with another lesser unit I might be able to swap out the whole drive carriage. I have a JE-630 stuck in storage as a backup. it doesn't sound as good as the 940 and doesn't have MDLP. I thought id sacrifice the 630 for parts. To my surprise, the drive is totally different. Are there other decks that have the identical drive as the 940? If so, are the electronics, boards and laser identical? ..the ribbon connectors the same? thanks a bunch for the insight! dave w Quote Link to comment Share on other sites More sharing options...
