Well, thanks to this thread, I found a taker for my M50. To be honest, the only thing these things are really good for is to learn on (I guess the EQ is useable). I was thinking about trying to mod mine just to practice my pathetic soldering skills, but I'm glad it's going to someone who actually wants to use it and must now learn about gain staging for low noise and how to clean pots and switches. I remember I paid $2000 for it back in '86 along with an 80-8 for $2500. I still have the tape deck and you can pry that from my cold stiff fingers when I die.

O-amps swap-out & smeary sound.

Unsure of protocol in referencing YTube sources so will keep it general; an excellent 15min-odd M-5a walk-thru & “tear-down” showed o-amps to be 4559s. Mention made they were top-notch in the day but that sound would certainly benefit with modern day swap-out. Was interesting to this newb that I could clearly see that component number imprinted. Sooo, I bet my 5B has 4559s too, which were mentioned as upgraded from the previous model’s 4558s. Will enquire into “LMEs” when overhauling the board (again thx Jim).
Have also noticed all 8 channel Aux Send/Rcv loops are missing those RCA-RCA jumpers (They’re on the 4 Sub-mstrs & Expansion jacks though). They’re those factory RCA patches that look real flimsy. Question; can I instead use the ones that look like giant staples that I’ve got on my 244 Portastudio?
Also, are those Solo buttons suppose to latch when pressed or has one gotta engage something else first? Glaringly obvious to more experienced ... sorry.
So I bet until I fix the Jumper issue I ain’t gonna get any sound from my board.
Cheers 4 now ...

A gentleman I worked with modded his Model 5 with a pair of 9V batteries providing 18V phantom for the mics of the time, usually AKG 451s. Made some nice records with it - notably Kate Wolf's Back Roads.

About all you need to do is add feedback phase compensation caps to the opamp feedback loops lacking them and add some local .1 uf psu bypass caps. DC offset is so low most of the el coupling caps can then be removed.

Wow, what other mics were used on that album? That album sounds ridiculous. Very clear, fat sounds. Other mics on her voice that you can think of than the 451? Thanks a lot for this bit of knowledge.

I think the OP may be confusing RCA jacks for 1/8"
Now THAT is a MAN'S studio......just looking at that photo makes me want to do a bump off the board, pull a firearm and forcibly confine some ****ty band to the storage room........Man, recording used to be FUN!!

The 5 is an ok mixer, as long as you don't fall into the trap of comparing it to real vintage high end gear. If it's in good shape (pots cleaned, connections burnished) it's can be a nice sounding mix board. Ok, so you're not gonna get a Neve, AMI, or Quad 8 flavor from it, but the channel strips are solidly built, individually framed, and have a decent xfmr mic preamp. When most people complain, it's about the EQ, which is a 2 band switch selectable range design. Heck, even that wasn't as bad as some would have you believe. At the time these were marketed, they were fairly state of the art & competitively priced for the budding home studio musician crowd. In fact, they were top of the line given the other options in that price range.

I have some very nice mixes from my Tascam Model 35 days. Tracks that still sound good run through much higher end, modern gear.

You aren't going to get squat on eBay for this gear. I'd say you are better off using it in a workhorse capacity, where some abuse is likely. It is built tough enough to handle that type of environment. Otherwise, I'd try to sell it local first, and not have to deal with shipping (it's real heavy).
Perhaps he mistook the RCA phono style connectors for ⅛? Apart from mic ins, Tascam series 5 used RCA.

*DUH ME! Thread is from 2007
