Thanks for hosting this. My hard drive at home crashed and I didn't have a backup of this particular file.


Nice find, thanks for sharing.

Thanks Ki, I 'll probably keep an eye out if a good deal ever pops up on eBay for a USB 2.0 one.

On the other hand, if there are significan hardware differences due to age, then it is good to back up both.  Judging from the years and versions PG16811A and C, both deck should work with C version.
Just an FYI I did swap the two and report no problems.

With help from one of the TP forum members, I have successfully revived the IC10 from the 25/91 firmware set and have finally archived the complete three BIN files.
Cool that you got that worked out.

Ki, can you recommend a Eprom programmer and Eprom eraser? I fiqure it wouldn't hurt to own and learn how to do this.

Hey Ki, what do you know about the eproms in the Otari BIII-2.



Didn't catch your edit till now, nice research and thanks for the links.

I started to think more about this and realized that I could turn my spare MX5050 BII2 basically into a MX5050. The deck does need an overhaul but does work and is in decent condition.

This is not a priority project but I did jump into it just to see.

Here is what I did:
Removed the record reproduce amp.
Removed all XLR's.
Removed wires from plug on headstack.
Removed remote plug and wires back to the switches and control pcb.
Removed blue wire from record led to control pcb.
Removed all of the wires from the control board that plugged into the record reproduce amp. (see pic for details)

All of the above would be easy to reverse.

A direct head wire now has a clear routing without any electronics in the way. One problem is the deck is now top heavy but have an idea to fix that. Another thing to do would be install dummy heads in place of the record and erase heads and another would be to look into removing all components from the control pcb that were used for the record reproduce amp but not sure if if that is really needed yet. Like I said this is just a project for another day but do see potential. One good thing about doing this is I am learning the schematic and its relation to the components in their actual layout.

If the pic isn't clear I can email a high resolution one.

Is there a list out there with what decks that meet this criteria.

I noticed the Ampex 934 that Doc used when he modded the seduction in his article here.

Just thinking if you have plans to already use an external repro amp and your needs are only for playback it would be easier to troubleshoot something like this when the need arised.

Decks that use 10" tapes would be of most interest.

Hey Doc, being green to this that was one thing that was puzzling me about an all in one tape.

Just so I get this clear two alignment tapes like in Charles post above would be needed. One for NAB 7.5ips 1/4 track (prerecorded tapes) and the other for IEC 15ips 2 track (tape project tapes). Don't see a need for NAB 15ips unless you have plans to record in this format.

What about adding a series of pops to check polarity at the speakers like on the Tape Project alignment tape mentioned in the last paragraph of Doc's post here.,685.msg3870.html#msg3870

I haven't used a alignment tape before so I do have a few questions that could use some clearing up.

IEC 15ips part would be needed for 2 track and the NAB 7.5ips for 4 track. Does this need to be specified? What abut NAB 15ips?

Did you ever get a reply from MRL?

Hey Charles,

Looks like this has gained at least 6 interest already :).

Here is a post Doc made in the past of what is on his alignment tapes.

I would say this would be the minimum requirements for an IEC and NAB alignment tape at 15 IPS.

One question I have is what would be needed on the tape to check the accuracy of a IEC and NAB eq?

Doc can you or anyone else chime in on anything else that would be needed on a tape like this?

I think for NAB 15 IPS and 7.5 IPS is considered the same so if you have the IEC tape from the tape project then all you would need is a NAB 15 IPS calibration tape.

I'm up for it since I don't have the tape project calibration tape and would love to have an all in one.


I don't have any experience with either or but do you have a link to the schematics.

Why not look at the Eros.

Some of them are .rar compressed files so you need a program that opens them. They have some free rar programs if you do a search.


Tape Project Machines / Re: Pondering a Seduction & Otari Mods
« on: March 23, 2009, 02:40:03 PM »
Is the CS4 upgrade only available in kit or can you get it included say in an assembled Seduction tape head amp?

Thinking about the direct-head wiring...if the head output is direct wired then the deck would only function as a 2-head machine like a 2 head cassette deck?  i.e. you wouldn't be able to monitor with the VU meters flipping back and forth between source and tape...only source?


Here's a seduction with the CS4 in Doc's Stash on sale.

What kind of line stage do you use? I hooked a seducton to my Hagerman Clarinet which only has 15dB of gain and didn't have enough output as I would have liked. Jay hooked the Seduction to his Rogue 99 that has 23dB of gain and had allot of headroom. My point is if you will be using a line stage with low gain the Seduction may not suite you and you should consider the Eros which would probably be an all around better performer with more gain.

If you have the headstack with the 2 and 4 track heads both will work with the direct head wiring. The heads are mounted to a pcb with the 2 & 4 track switch, this pcb plugs into a juntion block plug. The wiring for the direct head out is done behind the junction block so in essence it is wired after the 2 & 4 track switch. You can see some pics here.
and the wiring here

You could certainly monitor the sound if the  external tape head preamp were connected to a tape monitor type line level input on your control unit. But the play head can only be connected to one device at a time, so if it is disconnected from the internal playback electronics in favor of the outboard tape preamp the internal VU meters will not indicate with the Otari switched to tape. They would still show record levels on source.

See this thread for another way of looking at using the VU meters during playback.,792.0.html
Jay hooked his up like this with his Rouge 99 and reported no problems in doing so.
