ABOUT ME & MY TAPE RECORDERS

OPEN REEL RECORDERS
Alignment, repair and restoring of Revox and Telefunken tape recorders (and every audio device they can get the schematics).

Audio circuits UPGRADES with new "audiophile grade" caps on audio patch and power supply, low noise transistors, internal wiring with hi quality cables (HiEnd cables on request), optimized machines for replay only (direct signal patch from heads to preamp output bypassing every switch), tweak on request. Servo control logic UPGRADES.
Please go page servicing and spare parts & accessories for more details.

MAGNETIC TAPES RESTORING AND TRANSFERRING
I'm fully equipped to read every kind of tapes with Dolby A, B, SR e DBX noise reduction too and make reel to reel analog transfer with professional studio machine or digital transfer up to 24 bit 196Khz using worldwide acclaimed professional HiEnd Benchmark A/D devices.
Feel free to contact me if  you need tape restoring.


Simply because nothing sounds as good.
Great dynamic range, headroom, low distortion (if even "smooth and harmonic" distortion not breath and "sound" taking digital one) give the most natural and pleasant sound you can get. The RtR recorders rediscover and diffusion in professional field these last year tells you a lot.
At last: did you ever see these machines live? They are charming, strong built, very beautiful and are a mile stone in the last century history because they recorded all the music played and every main event occurred!


Revox were produced in many thousand pieces so you can easily find them on the second hand market and find the spare parts too. Revox reel to reel recorders were "bullet proof" built: simply but accurate they have a fine sound and a particular that makes the difference from other main firms high quality recorders: they don't have rubber part inside!  All motors are direct drive papst motor, with no belt, no pulley, no transfer, etc.  See the servicing page for this argument in depth.
Telefunken M15 or M15A is a giant ( weight 55 kg about without the case . . .) of the recording history. It is the son of the "Magnetophone" the first magnetic recorder built by AEG Telefunken in the early 30ties (see history page) and it was used in many recording studio across the Europe as its competitor the Studer A80. It is an high grade built machine both in electronic and mechanic (no rubber inside except the capstan belt that today they can easily replace with a standard belt). The selling price was DM 20.000 in the second half of 70ties but the constructive level was such high that its production become uneconomical for Telefunken factory in the last years.
From aesthetic point of view the definition "Hi-Tech" could be reductive despite it is 35 years aged and "touching" appears to be the right term to describe the care used in its construction.

To repair, align and restore audio electronic devices they need something more than a screwdriver. I have professional analog instruments in my lab. Why analog instruments? Because you can find them used at reasonable price, can repair and align them without big problem because they don't have smd components or custom i.cs and . . . they are analog!
