Re: Reel to reel revival
In "modern" times (omitting the early Grundigs) I think B&O used a cast chassis on the 1800 and 2400, the last flowering of the top-line Beocords before they went cheap and lightweight, but haven't seen one in the flesh. In any case, they now suffer from the curse of the bd Bogens.

Re: Reel to reel revival
Having both a Tandberg TD20A that I modified to 1/2 track heads and a Revox B77 Mk2. I really cannot hear any difference between the two. Both have good and bad points
The Revox has a cast chassis and Papst style motors, the Tandberg a pressed steel chassis and squirrel cage type motors driving a flywheel. Both were deemed acceptable as master recorders. I do not think that there will be a revival in R-R as the cost of tooling up something like either a Revox type or Tandberg type would be astronomical and the market would be very very small. Most people don't want the fuss of lacing up etc when you can just press a bottom and record to HDD or SSD. I suppose those of us that have R-R, have them because they know how good they can be, and curse and blind when the tape sheds or spools off or breaks, or the myriad of other problems that can affect our enjoyment. I suppose it is really like owning a vintage car. John |

Re: Reel to reel revival
Tooling costs aren't what they used to be 3-D printing may not be good enough for final parts but it can make models to take moulds from. There are a lot more CNC machines around for machining parts from solid. Water jet cutters and CNC punches/nibblers can replace hard press tooling.
I still suspect the market is too small to excite anyone for commercial manufacture, but someone with machinery might do something just for the fun. You can bung Gerber files out to firms in China and get cheap PCBs back that are dramatically better than Revox/Studer quality.... tracks stay attached! David

Re: Reel to reel revival
Is that just a Joie de vivre comment or do you really mean it? If the latter I'd like to see evidence because I think you will find that many people think otherwise!!

Re: Reel to reel revival
Hi Steve,
I knew it would be a bit controversial, and it was a bit tongue in cheek, but here’s the truth… That tape recorder, although looking brand new and in mint condition in the box, has actually been hammered. It was bought brand new by the drummer of the band I was in during the mid 70s and was used to record the band live on many occasions, he also used it at home as part of his sound system. When the band split up, I bought the recorder off him, I also bought his drum kit, but that’s another story! Those pictures of it were taken a few years ago when I happened to find the original box and packing in the loft. That tape deck has had hundreds of hours use since I bought it around 1976/7. It recorded all the best sessions and tracks from the John Peel and Tommy Vance Friday rock shows over the years when they were being broadcast, and played back the recorded tunes many times over. Also, a lot of full albums were recorded on it. It has always been my main reel to reel tape recorder over the years and has never gone wrong, other than several years ago it had started to get sluggish on rewind. I opened it up suspecting it may need belts, but it just needed slight adjustment and its 40 year service, including a dodgy earth on an edge connector that needed sorting out. The sound is as crisp and clear as the day I bought it, sound stability on piano music is spot on. It’s never, ever broken, chewed or spun off a tape, even with lightening fast operation of the servo buttons from forward to reverse to play – unlike a lot of these other machines being discussed at the moment. Nowadays however, it gets very little use. What can I say – the machine speaks for itself, although I’m sure if you ran technical tests on it then you’d find that it's probably lacking in comparison to some of those other machines. |

Re: Reel to reel revival
I haven't used late Grundigs much, but thrashed a TK8 when I was a nipper, and it took it all and came back for more. Only thing that stopped it was the head wearing down practically to the windings.
In my view, the downfall of Philips and Grundig in this field was taking on Revox in the NAB reel semi-pro class of product. I don't think they had a clear idea of the customer they were aiming at and, certainly in the case of the Philips 4520/4522, the mechanics were woefully under-engineered. Granted, the specs were OK, but use them hard for a while and things were different. |

Re: Reel to reel revival
To be honest, if I wanted a 'vintage' tape-recorder I'd need it to be portable, since most of my listening these days is done on-the-go.
A Uher Report 4400 or a Nagra IV-S would do nicely! |

Re: Reel to reel revival
Having started and watched this thread develop, it's time for me to chip in.
There is patently a tangible demand for a new, versatile, affordable, good audio-quality 'domestic' tape-recorder (and semi-pro Thorens/Ballringer) - production of which should also overcome the problem of those many serviceable decks with dead heads and motors. But what spec? Clearly professional/studio decks are affordable to the music industry, but not to the average 'audiophile' such as us. Decks: Forget expensive, unmodifiable Revox-style cast-alloy skeletal frames and go for simple, braced, on demand laser-cut cast-alloy 3-motor deck-plates machined to accommodate 5", 7" or 10-1/2" spools, Brenell fashion, with mechancial links and, optionally, solendoid control. Motors: There are clearly suitable modern, compact, printed circuit fractional horse-power motors which could be employed. By careful engineering design, it should be possible to design universal fit mounting plate adaptors to replace dead motors in a select range of older tape decks - such adaptors have long been used for camera lenses. Heads: Clearly if cassette decks are still being made, then so too are heads. A decent, 1/4" head and a range of universal fit adaptor plates is do-able... as is a swappable 2- and 4-track head block with modular electronics - its been done before. Modern digital technology allows affordable low-volume production almost 'on demand', so all it needs is an entrepreneur or two with crowd funding and moral support by forums/users such as us. Let's do it.... or lose it! |

Re: Reel to reel revival
There are at least three manufacturers of RTR tape....RTM in France, ATR in the USA and Splicit in the USA (who outsource). All the tapes are of very high quality.
The problem with RTR is that it was always pretty expensive to begin with...and the machines are complex mechanical beasts. It will never be "cheap" even if there is a revival. |

Re: Reel to reel revival
I've got a 60s Cossor portable (Phillips in disguise) and I keep meaning to use my hi-fi Akai to make a mix tape for it. I do wonder what people would think!

Re: Reel to reel revival
The Lyrec Frida (not Fred, that was a different animal) did something along these lines, also being very compact and using modern DC motors. Most of the functions of the Studer A807 happen in software - there is one tension sensor, but most of the heavy lifting is done by tachos on the spooling motors.

As of course were the 9-track reel-to-reel data tape drives used on minicomputers. Some of those didn't even have a driven capstan, just a tachometer sensor that measured the surface speed of the tape going onto the takeup spool which was used to control the motor speed appropriately. Take a look at the Cipher F880 service manual (to mention one such drive that I have a couple of (operational) examples of. But I suspect the tape speed is rather less critical in such a device than in an audio recorder. |

Re: Reel to reel revival
Capstanless drive is certainly possible and I know of at least one Film Scanner that works very well using this technique but I think it would be problematic for audio tape because of wow and flutter problems caused by having the tape controller (spool motors) such a relatively long way from the tape heads where to instantaneous speed needs to very closely controlled.
It is also hard to see how an instant wow free start could be obtained though this is probably less of a problem now tape machines are not used in broadcasting. |
