Displacement Miscellaneous
Since 2008 we have been producing the replacement for the relay NF2EB or NF4EB on a professionally manufactured double-sided circuit board. It all started with the Revox B780 receiver. At times there were the original relays for over € 35.00 + 19% VAT. That was too much for us! In the meantime, the originals no longer exist.
A short time later we also had a professional solution for the ITT relays A26xx with 5 V, 12 V, 18 V and 24 V in our program. The relays on the monitor board of the Revox B77 or Revox A77 Record relays fail more and more often. Repairing the relay or replacing it with another old relay will not lead to success!
The replica of these relays is used only to preserve many Revox devices.
For new developments you should do without this adaptation and use the right relays!
Installation of the replacement relay
Panasonic
NF 2 EB
Zettler AZ7-2C
Original NF2EB
The original relays NF2EB or AZ7-2C have 3 connections on one end. This connection should probably serve as a shield! Revox has provided a soldering point in the layout which is always grounded!
NF2EB reproduction
At this point our replica has a soldering point that is not used and equipped. If you bring the soldering points of the circuit board and the soldering points of the equivalent circuit on top of each other in a congruent manner on the respective circuit board of the Revox device, the assembly is correct!
equip correctly
If the solder points are congruent, everything fits!
NF2EB reproduction
Even if it may not be that crucial;
our layout is optimized for the smallest audio signals.
All conductor tracks are laid out round and are particularly wide. In addition, the conductor tracks are laid twice. Even with something trivial like a replacement for a relay, we pay attention to small things!
NF 4 EB from Panasonic
AZ7-4C from Zettler
Original AZ7-4C
As with the NF2EB or AZ7-2C relays, the NF4EB or AZ7-4C relays have a fifth pin in the middle on one side. This connection should also serve as a shield! Revox has also provided a soldering point in the layout, which is always grounded!
NF4EB reproduction
At this point our replica has a soldering point that is not used and equipped. If you place the soldering points of the circuit board and the soldering points of the equivalent circuit on top of each other in the same way when assembling the new circuit board of the Revox device, the assembly is also correct here!
Displacement Miscellaneous
Here tooour layout is optimized for the smallest audio signals.
Here, too, all conductor tracks are laid around and are particularly wide. In addition, the conductor tracks are laid twice. Even with something trivial like a replacement for a relay, we pay attention to small things!
If the soldering points of the Revox PCBs are congruent with our replacement circuits, everything fits!
ITT A26xx
ITT A26xx
We offer the replacement for the ITT relay A26xx with 5V, 12V, 18V (for Revox A700, A720) and 24V.
You shouldn't use any of the old relays anymore!
If the relays still work, then they are very limited in time.
Displacement Miscellaneous
The relay, the equivalent circuit can only be equipped in one direction.
As with the replacement for the NF2EB or NF4EB relays, all the conductor tracks are particularly wide, round and double.
Studer A80
The revox-online replacement circuit for the ITT A26xx relays fit in 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
Only a relay of type ITT A2610 is installed on the monitor board 1.077.260 of the Revox B77. But our equivalent circuit fits 100% here too!
