We have created complete upgrade kits, as well as custom faceplates, for the most popular Revox reel to reel decks CD player and Power Amps.

Two types of kits are offered, one with transistors and one without.

Every electrolytic, as well as tantalum capacitor, (tantalums are replaced by electrolytic's), is supplied, trimmer pots, as well as all audio and power transistors (if ordered). Each kit also includes a new set of motor start/run capacitors and the X2 film safety capacitors.

This will enable you to carry out a complete recap of your Revox audio gear.

And if you wish, by ordering the appropriate kit, all transistors can also be replaced.

Parts

 We no longer ship outside the USA!

We only use name brand capacitors, such as Nichicon, Panasonic, Vishay, Philips etc, and where ever possible, audio grade capacitors are used, which make up about 95% of each kit.

For the trimmers, we use the Piher brand.

For the transistors, we mainly use Fairchild, to ensure quality and reliability.
