WANTED Manual for MTR90 MKI

[mg73]

does anyone have an PDF version of the manual for MTR90 MkI?

 

[Michael Tibes]

I am not entirely familiar with the MTR 90 History, but I belive I have a copy of the manual, though on paper only. If there's no other solution, I could scan it, but it might take a while til I get it done...

Hi michael.

i mostly need the alignment partchapter for the transport.
But if it´s not for Mk1 don´t worry.

thanks.

How do I indentify what MK it is that I have? I just know that it's an early MTR 90...

Otari decks have a big tag on the back with the exact model and serial number on them. Also should say "made in japan" on the lower left corner of the tag.

Now where that tag is on an MTR I have no idea...

Have you talked to Brian Roth over at gearslutz.com? He's one smart cookie when it comes to tape machines.

I don't have a "secret decoder ring" for the serial numbers of Otari machines.

However, the Mk1 machines had a cluster of "jumbo" fuses installed in quarter-turn holders on the panel located on the left side of the electronics array, towards the bottom. I believe by Mk II the fuses were replaced with circuit breakers.

Yep my machine has those big quarter fuse holders.
But some said that there were alot of revisions of the MK1

Michael,


There are a lot of mark to look at, but a distinct mark are, if there are a fast wind "jogging" fader in front of the heads, it is a mk1, or if there are a tape editing/splicing block instead for the jogging fader, it is a mk2.

(and if the head top cover are in metal/chrome, it is a mk3)

[Michael Tibes]

OK, so my machine seems to be a Mk1 then... I have a paper copy of the users manual and the circuit diagrams. But I don't have alignment procedures for the transport - if I get you right that's what you're after?

Michael

 

[mg73]

yep that´s what I want
got some new rollers and swingarms and need the correct guidence.

Just wondering if you got the information you needed. BTW, the serial number indicates the machine was made in May of 1981 (ignore first number, next two are year, next two after that are month, rest in production info, suffix letter is referred to as "Lot" number). With that date and lot, the machine would have been one of the later Series I machines built.

The series I had TONS of mods done to it. For proper alignment, it is important to get the instructions that match the Lot and what ever mods have or have not been done to it. I used to work for Otari (87 to 91) and for an Otari dealer before that. Don't have all the manuals anymore but I know someone who does so if you still need the alignment procedures, let me know.
