The ReVox open reel decks are amongst the highest regarded decks ever made. The Swiss/German engineering and production lead to a quality that yet has to be beaten by any other manufacturer. These decks are easy to service and maintain. They work like the proverbial swiss clockwork and will satisfy audiophile requirements in performance. This particular deck has received a large amount of service and restoration work.
The case is made out of quality plywood that has been coated in polyurethane. It is the first prototype of our CNC made replacement case for A77. The deck was original stuck in an ugly grey suitcase style case. The paint on the two pickups started to peel off due to age and both pickups have been fresh powder coated. The VU meters are unique on this unit and will leave most people stunned – they have been replaced by two OLED display with graphical VU meter representations – full functional and calibrated of course. On the technical side the below service has been carried out:
- Replacement of 37 capacitors on motor control, input and record amplifier boards
- Replacement of Counter Belt
- Lubrication of capstan with high end synthetic oil
- Treatment of original pinch roller with special rubber formula
- Demagnetisaiton of heads and capstan
- Adjustment of breaks
- Cleaning of the inside from dust
- Replacement of some screws and other hardware with stainless steel ones
- Full functions test (passed with flying colors)
We also added some decals on the left side that we have designed and called it “A77 Digital” because of the digital VU meters. Overall a great looking deck that performs at the highest level. Please check specifications below for further details. This is standard Stereo deck running at 7 1/2 or 3 3/4 inch per second. Rell size from 5″, 7″ up to 10.5″.
The A77 Comes with the following Acessories:
- 10.5″ Black ReVox Metal reel
- 2x Smokey Grey NAB HUB Adapters
- Power Cable (90 degree plug to be invisible)
Feel free to call us if you have any questions or want to audition/view the unit.
Description
The well known reliability of the Revox A77 is a result of a professional design concept, a concept which successfully combines the advantages of a solidly built tape transport mechanism with those of an advanced electronic circuit design.
A 3 motor transport mechanism with electronically regulated capstan motor and solenoid operated servo brakes possesses few parts which are subject to mechanical wear.
The use of a die-cast motor chassis and head support ensures that a high degree of mechanical precision and long term stability are maintained, even under excessively heavy use.
The mechanical and electrical properties thus complement each other in a most successful way.
Models include the A77 professional, A77 SLS (super low speed) for up to 12 hours of recording, and the A77 Autostart (Vox) for security applications.
