Replacement relay
Since 2008, we have been manufacturing replacements for the NF2EB or NF4EB, or AZ7-2C or AZ7-4C relays on a professionally manufactured double-sided circuit board. This started with the Revox B780 receiver. At one point, the original relays were available for over €35.00 + 19% VAT. That was too much for us! The originals are no longer available.
Shortly thereafter, we also added a professional solution for the ITT A26xx relays with 5 V, 12 V, 18 V, and 24 V to our product range. The relays on the monitor boards of the Revox B77 or Revox A77 record relays, etc., are failing more and more frequently. Repairing the relays or replacing them with another old relay is not successful!
The reproduction of these relays serves exclusively to preserve many Revox devices.
For new developments, you should avoid this adaptation and use the appropriate relays straight away!
Installation of replacement relays
NF 2 EB from Panasonic
AZ7-2C from Zettler
NF 2EB, AZ7-2C
The original NF2EB or AZ7-2C relays have three connections on one end. This connection was probably intended for shielding! Revox has provided a soldering point in the layout at this location, which is always connected to ground!
NF2EB replacement
Our replica has an unused soldering point at this location that will be populated. If you align the soldering points on the respective Revox device's circuit board and the soldering points on the replacement circuit so that they are aligned, the assembly is correct!
equip correctly
If the soldering points are aligned, everything fits!
NF 2EB, AZ7 2C Ersatz
Even if it may not be so crucial;Our layout is optimized for the smallest audio signals. All traces are rounded and extra wide. Additionally, the traces are doubled. Even with something as trivial as a relay replacement, we pay attention to the smallest details!
NF 4 EB Panasonic
AZ7-4C Zettler
AZ7-4C, NF 4 EB
Like the NF2EB or AZ7-2C relays, the NF4EB or AZ7-4C relays also have a fifth pin in the middle on one side. This connection was also supposed to serve as shielding! Revox has also provided a soldering point at this location in the layout, which is always connected to ground!
NF4EB, AZ7 4C
Our replica has an unused soldering point at this location that will be populated. If you align the soldering points on the respective Revox device's circuit board and the soldering points on the replacement circuit so that they are aligned, the assembly is correct!
Original and replica
Here, too, our layout is optimized for the smallest audio signals. All circuit traces are rounded and extra wide. Additionally, the circuit traces are doubled. Even with something as trivial as a relay replacement, we pay attention to the smallest details! If the soldering points on the original Revox circuit boards align with our replacement circuits, everything's fine!
HERE A26xx
HERE A26xx
We offer the replacement for the ITT relay A26xx with 5V, 12V, 18V (for Revox A700, A720) and 24V.
You should no longer use any of the old relays!
If the relays still work, then it is only for a very limited time.
Ersatzrelais
The relay, the equivalent circuit, can only be fitted in one direction.
As with the replacement for the relays NF2EB or NF4EB, all conductor tracks are particularly wide, round and laid twice.
Study A80
The premium hi-fi replacement circuit for the ITT A26xx relays fits all Studer and Revox devices.
The Studer A80 oscillator circuit board is available with 2 relays 1.080.984 and 1.081.987 or 3 relays 1.080965.
Revox B77
The Revox B77 monitor board 1.077.260 only has one ITT A2610 relay installed. But our replacement circuit fits perfectly here too!
