Finishing

Also called tuning in cars
The refinement of Revox or Studer devices primarily serves to improve the sound through suitable measures such as the installation of the toroidal transformer, the possible omission of electrolytic capacitors, the use of bypass capacitors and the use of special audiophile electrolytic capacitors from Panasonic, better transistors, op-amps and other semiconductors, pair selection and other possibilities known to us.

In contrast to the automotive industry, tuning here is not for visual individualization.
This is much more about an improvement in sound, a higher resolution, better audibility, a dry, powerful, precise bass, and precise spatial gradation of the instruments and voices.
For us at Premium-Hifi, improved usability is also a refinement. Our expanded RCA jack spacing to 15 mm provides a much better connection to the outside world. You can use high-quality audiophile RCA cables from many well-known manufacturers and no longer have to make compromises. We can also use better systems, from Clearaudio to the Charisma V2 series, to get the best possible performance from your Revox turntable.
Since the upgrade brings about a significant improvement in sound, you may find that your Revox or Studer device is no longer recognizable. This, however, is undesirable and even frowned upon by most enthusiasts of these devices. However, there is a great deal of potential in Studer and Revox devices; why not take advantage of it when it's so easily possible today?
For Premium-Hifi, finishing can include the following points:
Replace cut-band transformer with toroidal transformer
Avoid electrolytic capacitors in the signal path as far as possible
Bypass capacitors to the electrolytic capacitors
Replacement of the electrolytic capacitors with high-quality, audiophile, low-distortion and low-noise electrolytic capacitors from today's production
Replacing standard film capacitors with better KP, mica or polystyrene capacitors
Block capacitors to active semiconductors, ICs
Support capacitors on all circuit boards and assemblies in a reasonably large capacity
Extension of the RCA sockets to 15 mm to accommodate even the best RCA cables
Replace standard transistors with low-noise derivatives, possibly with non-magnetic emitter resistors
Optimization and filtering of the operating voltage at the amplifier stages and modules
better, faster op-amp ICs with very low distortion and high channel separation
Pair selection of electrolytic capacitors, transistors, etc.

Which of these measures you want to take is up to you, but we would be happy to advise you.
We'll leave it up to you to judge the improvement in sound and the increase in value. Nevertheless, you'll be amazed at what's still possible with a Revox today!

In the audio sector, we use a bypass capacitor for every electrolytic capacitor; this is the only way we, as experienced audio technicians, can install a device in our living room. Even if it is claimed that bypasses are of no use in terms of measurement technology and that Revox would otherwise have installed bypasses themselves,
Revox has installed bypass capacitors; you can even find bypass capacitors in the Revox B750; you just have to look closely instead of making comparisons with measuring device manufacturers!
There was also a claim on eBay that bypasses caused measurable and audible drops in the bass range. These stupid claims have since disappeared. Of course, bypass capacitors cause extra work—but it's your project—make the most of it!
