PANASONIC FC 4,7µF Low ESR for Tape-Drive-Control and Switch board
Encapsulated PIHER trimmer
Suitable motor capacitors

WIMA, Panasonic, Epcos... suppression capacitors

Include replacement for ALL electrolytic, tantalum, suppression and motor capacitors and for ALL trimmers that are installed in the Revox A77.

All radial and axial electrolytic capacitors as well as all tantalum are replaced by radial electrolytic capacitors.

Not included are the components for any built-in power amplifier, Dolby, or other optional boards.

Individually packed in bags and assigned to the circuit boards. 

Depending on the version, a few components will be left over. 

Due to the age of the machine, it is strongly recommended that these components be replaced. 
The old mini print capacitors are known to go up in smoke.
Most of the Franko and Siemens electrolytic capacitors are now defective.
With the trimmers, the sliding contacts simply rust and break. 

On the subject of bypass capacitors or coupling capacitors: I believe there is absolutely no need for that. If you want double the effort, you can of course do so …

Scope of delivery:

Capacitors and trimmers for all 7 audio boards as follows:

Your advantages:

- We only sell high-quality and original components from current production.
- When the components are dispatched, you will receive detailed instructions in German / English with a circuit diagram and circuit board layout as a .pdf file by email or as a download link. (Please check your SPAM folder if you have not received any instructions)
- We only sell components that we use ourselves in our workshop and have tested in the respective machines.
- We only sell components that also work in this combination, because this is often not the case with a combination according to the circuit diagram. Circuit diagrams often also contain errors, e.g. even then updates and new revisions.
- We only sell components with which the factory specifications are adhered to, or in most cases even exceeded.
- If you have any questions or problems, we are there for you and will be happy to help.

Several hundred machines were converted with these components without a single complaint.
This set contains all relevant vulnerable and failure-prone components.

The installation instructions describe how the old trimmers are measured with a multimeter. Then the new trimmers are first set to this resistance value and then soldered in. In this way, a new measurement can be avoided in most cases.

Soldering skills and basic electronics knowledge must be available!
In no case simply screw around the machine, the risk of adjusting something or damaging it is very high!

Precautions:
Lethal voltages exist in the device!
Please pull the power plug when working on the device!
Please make sure that no parts are lost or fall into the device! We do not take any responsibility for the work done!
