    MRL Question.....

    As I mentioned above, this is precisely the same list of conversion values as in table 5-6 from the MRL document I referenced, except that it takes care of showing the frequency doubling for you upon playback at 15 ips. Jay just assumes that you can take care of the IEC-IEC feequency...

    MRL Question.....

    Thanks. I wasn't sure what eq the machine would have. It's not too bad. You can use table 5-6 to go from 7.5 NAB to IEC, and it's the same at 15, but the playback frequency is doubled. The difference in level is no biggie. Its just a constant amount up or down. Easier to just calibrate to...

    MRL Question.....

    Sure. Check out table 5, page 9 of the MRL guide http://home.comcast.net/~mrltapes/choo&u.pdf If the tape is NAB 7.5 ips and you want NAB playback at 15 ips, you want table 5-7. If both were IEC, there would be no level adjustments, you'd just have to be aware that all the frequencies were...

    RMGI moves to France

    Any color is fine, as long as they print the formulation number on the back of the tape, though some here would like to see it made in purple. Cheers, Otto

    How Many Regular Members Are No Longer Here?

    (Raises hand to show his absence) Fall was even busier than usual at work. In my limited time for music, I've been playing a lot with fun synth apps on a loaner iPad, plus a bit of singing and playing electric guitar and bass. Still gets tracked to tape. So that's good... more music, less...

    How hot can 32 and 34b heads be driven?

    1) probably the only danger to heads is the possibility of burning out the erase head, but the electronics probably aren't up to that on a Tascam. 2) as noted, MOL is maximum output level, and does not refer to an operating level. 3) you want the tape to distort before the record electronics...

    Analog recording something for the youth ? Or older nostalgia ?

    Yeah, it's funny, my first electric guitar was a Lotus of the Les Paul style and it has a great tone. Not quite as nice of a feel as the Gibson, but sounds super. I still have it and play it when I want a humbucker sound, plus it's tuned in the standard tuning, unlike the Melody Maker, which...

    Analog recording something for the youth ? Or older nostalgia ?

    Hmm... can't really say too much about Epiphones, but I'm pretty fond of my Gibsons. I got a Gibson Bass for about $200 back in 1983. Dealer didn't think much of it, but it sounded great after I had a tech rewire it to original spec. Got my Melody Maker in a trade years ago. Ironically, I...

    Analog recording something for the youth ? Or older nostalgia ?

    There are certain things required of you to use tape successfully, but it can be quite good and rewarding. If you are going to do your own maintenance and tech work, there is a skill set and some needed equipment that will have to be taken care of, or you will not be happy. In use, there are...

    Tapco 12x4

    BTW, I'm serious. I'd like to get an old Tapco console like this. My studio mentor from long ago had one and got good sound from it. If there were any beneficial modding to do, I'm sure he'd walk me through it. Cheers, Otto

    Tapco 12x4

    I'd take it, but I live far away, and they don't ship. If one of you good folk in the area would pick it up, I'd pay for shipping and reasonable handling fees. Just send a PM if that would work. It would certainly relieve your angst! Cheers, Otto

    What's the deal.

    I can't really speak to the whole site, because the only forum I visit here is this one. What I continue to see, looking at the threads, is mostly people coming here for help in doing something or getting stuff to work and other people helping them. Also a fair amount of people who know what...

    What's the deal.

    I'm always amazed the Tascam machines sound as good as they do. Seems like they should have paid a higher sonic price for using the same specs for record and play heads, or even using a single head for both, but they didn't. I don't have much experience calibrating two-head machines, but I...

    Discussion of early 16-track and 24-track machines

    Indeed. If you go to his website, one little page (among many) will tell you that he created a servo-controlled, direct drive capstan motor and electronics for the M-23. You swap out the flywheel, capstan motor, etc. and install a direct drive motor with crystal oscillator controlled servo...

    Discussion of early 16-track and 24-track machines

    The M-23/M-64 modules are 3U. I have seen a picture (maybe Dale emailed it to me) of a prototype successor to the M-23 that had 2U electronics, 8 channels above the transport, a la AG-440-8, but I don't that product ever went to market. That might have been an officially sanctioned prototype...

    Discussion of early 16-track and 24-track machines

    OK, here we have a separate thread to discuss the early 16-track and 24-track machines, so that Cory's MM-1000 project thread can keep its focus. My contribution will be modest, but I will start about by noting that I've corresponded with Dale Manquen about how he surreptitiously created the...

    modern tape machines?

    We each have our own approach to this. My preference is not to do that much editing or processing of recorded tracks. Certainly not to spend a lot of time tweaking tiny details. I find that I know my playing, instruments, room, mikes and recording technique well enough to get what I'm after...

    3M M64 Halftrack

    I scared myself the first time I accidentally shined a flashlight on the sensor while tape was threaded and the unit was powered up. I hadn't installed a working sensor bulb or tried to get that circuit working. So, I had the tape moving and it shut off when the flashlight beam hit the sensor...

    Inexpensive VU Meter Lamps, Bulbs

    FWIW, I buy standard numbered bulb types from 1000bulbs.com. Type 47 "Fender" amp light bulbs and miscellaneous bulbs for transport buttons. Type 1815 bulbs for Littlite model G, for example, are something like $2 for a box of ten. Just order a bunch of stuff at once, because the minimum...

    3M M64 Halftrack

    All I can say is that 3M machines have a sound that can level cities. The earlier machines are a tad better than the M-79s, in terms of low phase shift at the high end. They are designed to drive 150 or 600 ohm loads and eat +4 nominal signals for lunch. To monitor the M-23, I unbalance the...
