Spare parts
for all Revox
B750 and B750 MK II amplifiers
B750 and B750 MK II amplifiers
Here, too, the list of spare parts is getting longer and longer! Here, too, we've compiled the spare parts and accessories available for all Revox B750 integrated amplifiers.
In-house productions
High-quality spare parts, accessories and circuit boards developed and manufactured by us
Phono Amplifier
Many optimizations that go far beyond the standard in the audio sector have been incorporated here. Buffering and channel separation of the voltage, the elimination of electrolytic capacitors, bypass capacitors, film capacitors in the signal path, and so on. The circuitry is Revox, the optimizations are premium hi-fi.
Filter Amplifier
All voltages are filtered separately for both channels via RC elements, LEDs instead of 2 diodes, wide conductor tracks, high-quality 2% film capacitors where it counts!
Power supply board
for all Revox B750 and B750 MK IIWith a longer cooling angle and additional heat sink. It features stationary charging capacitors and a current voltage regulator. The circuitry has been optimized for audiophile standards. Numerous additional capacitors filter out all noise and stabilize the power supply of the audio electronics. Here, too, the conductor tracks are particularly wide and 70 µm thick! The output voltages can be set to 40 V or 48 V via jumpers.
Protection Circuit
With additional relay and terminal block for the pre-amp output. Three LEDs indicate the readiness and speaker selection (A or/and B).Here, too, the NTCs of the power amplifiers are monitored, the /- DC voltage at the loudspeaker output as well as the operating voltages 20 V, -20 V and -10 V
Balance Amplifier
The effort we put into filtering the operating voltage is enormous. Each of these amplifier buffer boards requires four additional electrolytic capacitors with their bypasses and four resistors for RC filtering.
Tone Control
Here, too, four small 47 µF electrolytic capacitors are installed as buffer capacitors, along with their resistors and bypasses. The circuitry remains 100% Revox B750. Where necessary, we use narrow-tolerance film capacitors in the signal path.
Filterboard
The new contacts on the three toggle switches are certainly worth mentioning here. The frequency-determining capacitors in the filter circuits are also all high-quality film capacitors with a tolerance of just 2%. Here, too, the conductor tracks are particularly wide, round, and 70 µm thick! Of course, everything fits perfectly. The circuitry is Revox, the optimizations are premium Hifi.
Distance extension RCA
With this RCA jack spacing extension, you can use all high-quality cables from well-known manufacturers with various Revox devices. Only the original Premium HiFi extension has 15 mm spacing! What good is 13 mm spacing, if it's still severely limited?
Speaker terminals
Brand new binding posts for all Revox B750 speaker terminals (A and B). The large spacing between the terminals allows you to connect the wires directly. However, you can also connect the terminals via the 4 mm banana plugs without the risk of short circuits.
Anything else makes no sense!
Spare parts specially manufactured for us
Spare parts specially manufactured to our own high standards
10.000µF 63V
Charging capacitors, filter capacitors for the devices Revox A722, B750, B780, C270 and Studer A807, B67 and so on in best quality from German production.Of course, the capacitors fit perfectly both mechanically (4 pins, dimensions) and electrically. If GOOD isn't GOOD enough for you! HIGH GRADE Audio/Power
CAP
370 VA transformer ring
We pre-assemble the transformers and group them together. The wires of the power amplifiers (red) are fitted with 2.8 mm x 0.8 mm flat plugs. We manufacture the transformers according to the current EU standard EN 61558. The transformers are CE-compliant!Work with extreme caution and concentration and have the work checked by a professional.
230 Vac / 115 Vac can be fatal!
We assume no liab ility for your work!
Power cable
We also manufacture special two-pin power cables!2.50 m long,grey, angled plug
toggle switch lever
The weak point of toggle switches is the plastic lever. Since new switches were no longer available, we immediately began developing and manufacturing this replacement part.
