I just bought a Marantz Model 140 amp and it has the original wood case. I should be getting it next Friday. Of all the vintage mid-70's Marantz units I have, none of them have had wood cases while in my possession. Before I take it to my tech to go through and restore properly, I may want to remove the wood case and re-finish it myself. (the case) I'm curious how the wood case is attached? Are there set screws? What holds it in place? Does it slide right in and out or is there more to it? Thanks for any info!
