Speaker terminals for
Revox B750 MK I & MK II
Does it make a difference in terms of sound?
However, you can connect cables as you wish without reducing the cross-section or fraying the copper wires. The larger spacing between the terminals makes them extremely easy to use!
Elsewhere, the terminals are so tight that if you use bananas they can cause short circuits.
Speaker terminals
for Revox B750
Scope of delivery
The scope of delivery includes:
a sturdy black epoxy circuit board with all holes, labels and 2 ground planes,4 pole terminals ground and 4 pole terminals signal,6 bolts and nuts, 6 toothed washers, and 6 U-washers. You don't need more than 6 fasteners for a secure fit!
The speaker pairs
Elsewhere, "only" the speaker pair "B" is changed, and then it's much too close together, so there's no better usability.
Okay, this requires more work, but it's worth it. This provides a real increase in comfort.
If you're going to renovate, do it right!
The connections
The pole terminals are color-coded.
The ground connections of the channels, the black and gray wires, must not be interchanged under any circumstances! A bridge is no longer necessary due to the continuous ground plane.
Distance
Only at this distance can the terminals be optimally operated and the cable be clamped and secured correctly. The risk of a short circuit is also very low. Even if you use banana plugs, nothing will happen. And that applies to both pairs of speakers!
The conversion
outbreak
You'll need more space for the pole terminals than for the speaker DIN connectors or the old terminals. To prevent scratching the back panel during sawing, a large area of it is taped over.
Intervention
Another intervention is carried out on the chassis of the Revox B750. Sawing is required here as well!
The markings are made using the previously sawn back panel. This is quick with a jigsaw. Then a little filing and you're done. The chassis cutout is covered by the new circuit board and will no longer be visible.
Comfort
A lot needs to be done to increase comfort!With a jigsaw and a little care, this can be easily accomplished.
The two pairs of RCA sockets "PRE AMP OUT" and
"PWR AMP IN" should also be removed for easier working.
"PWR AMP IN" should also be removed for easier working.
assembly
Montage
The RCA sockets can then also be equipped with the extended distance
(now only available in black).Drill two more holes on the right, and assembly can begin! Two mounting points are perfectly sufficient due to the sturdy epoxy circuit board.
Solder
Solder the stranded wires to the solder tabs of the terminal blocks according to their color. The colors are listed on the circuit board. Black and gray are soldered directly to the ground planes. A jumper like before is no longer necessary!
Ready
If it looks like this, everything fits.
The edges are painted gray. Speaker pairs A and B, as well as right and left, are labeled. All binding posts are easy and safe to use. You can connect the cables directly or use 4 mm banana plugs.
