High-quality components developed and produced by us
New boards for B77
We plan to gradually offer all Revox B77 circuit boards as new, optimized, and state-of-the-art versions. All Revox B77 circuit boards are now available. Of particular note are the power supply board with complete separation of audio and capstan voltage, the quartz-controlled audio motor control, and the drive control with motorized braking.
Power supply board B750
New power supply board 1.178.137 for all Revox B750 integrated amplifiers, featuring state-of-the-art technology and many optimizations for improved power supply, better sound, and a cooler environment!
Driver
for all Revox Studer B77 and PR99.
The carrier is located on the pressure arm and ensures that the tape is lifted off the heads and rests against the heads during record and play! The old plastic parts are breaking more and more often.(Image similar)
Device feet
For all Studer A807 tape machines. Device feet for the Studer A807 are extremely rare. Hardly any Studer A807 was ever ordered with feet. Our feet are manufactured using 3D printing, are extremely stable, and are a perfect fit for the Studer A807 tape machine. (Image similar)
Device Feet
For all Studer A67 or B67 and possibly other Studer devices. The plastic feet are increasingly breaking apart due to age. We at Premium-Hifi now offer suitable replacements for the brittle feet of Studer devices. (Image similar)
Studer A101
Replacement circuit for Studer A 101 hybrid module!
We've rarely seen so much nonsense about the various replacement circuits for the Studer Linear Hybrid Module A101. Here's a better alternative using SMD technology, which is very similar to the original hybrid technology and technically far superior to anything else!
Replacement TBA931
The original dual op-amp in the 14-pin package is also no longer available.
We offer you the replacement in three audiophile versions with
NE 5532,
OPA 2134
and LM 388.
Distance extension RCA
With this RCA jack spacing extension, you can use all high-quality cables from renowned manufacturers. Only the original Premium HiFi extension has 15 mm spacing! What good is 13 mm spacing when you're still severely limited in your RCA cable selection?
Relay for ITT
Since 2008 we have been manufacturing replacements for various relays to maintain Revox devices.
Our relays have a switching capacity of up to 2 amps - like the original relay.
We manufacture the replacement with 5V to 48V and can therefore supply all relays of the A26xx series. All our relays are fully assembled, with all contacts, and 100% tested!
Relay for NF x EB
We have also been manufacturing replacements for the NF 2 EB and NF 4 EB series since 2008. These relays are also available in voltages from 5V to 48V. All contacts are assembled and all relays are 100% tested.
Digital counter for Revox A700
and Studer A67
- 5-digit display
- LED technology
- Real-time display
- particularly easy installation
- no soldering required
Counter 77
In 2003 the first digital counter for all Revox A77, B77 and PR99 MKI was created.Real-time counting and speed detection are not provided here. As with the analog counter, only the speed of the right winding motor is recorded. Installation is somewhat more complicated than with the A700, requiring only two soldering points. Of course, you'll receive detailed instructions!
All digital meters come with seven different colored filter sheets. This allows you to set the color on-site or change it at any time.
Counter 700
Here, too, you can choose from 7 colors at any time by selecting the filter foils.
For each of the three speeds of the Revox A700, the corresponding played tape length is displayed in hours, minutes and seconds.
The meter readings remain after switching off!
VU meter A700
There are once again major supply problems with the analog VU meters for the A700! This is the only reason why we are once again offering LED VU meters for all Revox A700s. While stocks last, we can offer you analog VU meters from repair stocks. These stocks are very limited.
LED VU meter
After experiencing further delivery issues with the Revox A700's pointer instruments, we've reissued the LED version. We're not backing down in favor of the analog VU meters.
If we get analog VU meters again, we will offer them in parallel.

toggle switch lever
The weak point of the toggle switches is the plastic levers. Since new switches were no longer available, we immediately began producing this replacement part.
Ringkerntrafos
We offer audiophile toroidal transformers for the amplifiers:
- Revox A740/B740
- Revox B750
- Revox B250

Andruckrollen für
Revox A77, B77, B710...
- real rubber
- maintenance-free
- Sintered bronze bearings
- Round ground
- Made in Germany
Andruckrolle Revox B77
For Revox B77, A700, PR99 and C270 as well as many Studer tape machines for 1/4" tapes.
Anyone who has ever seen the damage green pressure rollers can cause will understand why we've taken the time to develop our own pressure rollers. Here, too, the highest quality was our top priority.
Anyone who has ever seen the damage green pressure rollers can cause will understand why we've taken the time to develop our own pressure rollers. Here, too, the highest quality was our top priority.
All pressure rollers are oiled for the lifetime of the pressure rollers.
Andruckrolle A77
The pinch rollers on the Revox A77 have an axle length of 11 mm, compared to the 9 mm pinch rollers on the Revox B77. If you want to compensate for the difference with two metal washers, you can do without the pinch roller altogether. You can't ruin the synchronization more thoroughly than that!
Andruckrolle B710
Here, too, the quality of the pressure rollers was particularly important to us. It was important to us that no polyurethane was used. Likewise, we only use sintered bronze bearings. We've already discovered that plastic bearings are useless.
Attention! The Revox B710 is available with 8.0 mm and 8.6 mm pinch rollers, as well as with two 13 mm pinch rollers!
Andruckrolle B710, B215
The 13 mm pressure rollers are also made of sintered bronze bearings and rubber. These are also ground round after vulcanization. This is the only way we can guarantee synchronous operation that meets Revox's specifications!
The pinch rollers also fit the Studer cassette decks A710 and A721
Pressure roller accessories
In addition to the high-quality pressure rollers, we offer suitable accessories such as:
- Copper discs suitable for Revox B77, PR99
- Sliding discs suitable for Revox A77, B77...
- Sliding discs suitable for Revox B710, B215...
- Shaft retaining rings for the tape decks
- Sintered bearing oil
Charging capacitors of the
High Grade Audio/Power Cap Series
- Made in Germany
-105°C
- according to our
manufactured to specifications
- manufactured according to IEC60384
22.000µF 80V
Charging and filter capacitors for the power amplifiers Revox A740, B740 and Studer A68.These capacitors in the best quality of"HIGH GARDE Audio/Power CAP" series are a perfect match for Revox and Studer power amplifiers.Both the screw fastening and the screw connections fit 100%.
The nominal voltage has been increased from 63V to 80V and the capacitance from 15,000µF to 22,000µF. The external dimensions remain unchanged.
10.000µF 63V
Charging and filter capacitors for the devices Revox A722, B750, B780, C270 and Studer A807, B67 and so on.
Here, too, the capacitors fit perfectly both mechanically (4 pins, dimensions) and electrically. We at Premium-Hifi are so crazy when good isn't good enough for us!
22.000µF 63V
Charging and filter capacitors for the devices Revox B150, B250, B285 and so on.
These capacitors also fit 100% mechanically (5 pin, dimensions) and electrically.
Wherever Studer and Revox used charging capacitors with five pins, you can use the Premium-Hifi capacitors.
2.200µF 40V axial
We also have axial capacitors manufactured for us. The axial design, in particular, is unavailable anywhere in a quality that satisfies our requirements. These capacitors are used in Revox B77, PR99, B760, B750, B780, B790, and others. These capacitors are also part of our high-quality and popular "HIGH GRADE Audio/Power CAPS."
1.000µF 40V axial
The 1,000 µF or more recently
1.0 mF capacitors in Revox A77, A76, A78, B790, B791, B795 and many other Revox and Studer devices.If axial capacitors are provided in the layout, please also use axial capacitors.
Spare parts from our stock
From our work over the last 25 years we have been able to collect many spare parts
Don't expect us at Premium-Hifi to list all the spare parts for Studer and Revox devices that we can supply!It would also be presumptuous to say we deliver everything!
We have many spare parts reproduced, and we also produce many spare parts ourselves at Premium-Hifi. However, we cannot supply everything, especially the sought-after Spare parts are also quickly sold out.
The problem with spare parts is that frequently needed and sought-after spare parts are always quickly sold out, even at our company. The sought-after spare parts include, for example, LCD displays (more correctly, LC displays), ICs produced specifically for Revox, etc.But untouched front panels and controls, as is often requested, are extremely rare!
Is that why you judge us so negatively in this regard?
LC-Display
Every now and then we get some good displays! Often, however, the displays look like the ones in the photo!
Poti B780 B750
The combination of volume and balance pots from the Revox B780 or B739 has long since been discontinued. We're getting by by using the B750's volume pot and hard-wiring the balance to the center position. The matching knob also comes from the B750. It's not pretty, but what can you do?
Power switch B790...
The power switches on the Revox B790, B739, and B780 also frequently break. Replacements are no longer available. We have to repair the switches. They also operate at 230 Vac, so everything should be fine!
Processors Controllers
The supply of processors, controllers, and PROMs for various Revox devices is also becoming increasingly poor. Often, these are OTP types programmed directly by the manufacturer. Some ICs are even reproduced at our request.
VU meter
The original VU meters, signal, and tuning instruments are also almost nonexistent! Only the B760 displays are still available as originals, and they're incredibly expensive—but at least they're still available. Where else can you find spare parts for devices that are sometimes over 50 years old?
