Yamaha CS80

We are Brokering this instrument for and on behalf of our EU client.

Came into stock: Available from RL Music as at 28th June 2018, and this CS80 is currently located at our restoration partners – KSR in Surrey, UK.

Servicing Status: A full health-check by KSR has already been carried out (June 2018), so this CS80 is ready for sale now.

Remarks: This CS80 is an exemplary condition example that we sold to our client, the owner, in 2015 when the instrument was subjected to what we term a ‘Total Restoration.’

This CS80 we are offering for sale can be considered among the very finest examples in the world. It is still a 40-year-old instrument with its original keys & buttons etc., but the restoration work invested into it, plus the modifications listed below, mean this is a very special machine, and we have produced only a small number of these very high-level restored examples in the last 16 years for discerning customers around the world.

The CS80 has already been fully cosmetically and operationally restored (Level 2) by KSR. Only RL Music get the ‘’Level 2’ restoration as this includes a much higher level of detailed restoration by KSR, including a full key-bed restoration and point-to-point cabling/solder-contacts integrity checking for the entire loom etc. The Level 2 operational restoration normally costs £4000 GBP (in 2018). We’re pleased to confirm this CS80 already had this work applied of course and is included in the sale price.

The following work has been implemented:

The restoration comprises (not limited to) the total replacement of all the old CMOS Logic IC’s, all of the dual op-amps, voice card, and power supply capacitors & transistors. In addition to this the TKC circuit board, which controls the polyphonic aftertouch of the CS80, is fitted with a set of bypass/decoupling capacitors for each IC to greatly reduce the chance of failure of the touch response circuit. To cap this off, a full calibration is then performed (voltages to within 3 decimal places). The actual list of work is huge, and changes out several hundred components,  and includes a 7 day burn-in test period/stress testing.
All the RL Music supplied CS80s are serviced/restored by the world renown CS80 expert Kent Spong of KSR (Kent Spong Restorations) in London. Sound on Sound magazine (SOS) did an interview article on Kent, which you can find here:

Items of Note on this CS80 for sale:
Most CS80’s have lost their ‘Pedals, Music Stand and Legs’ over the years, so we are unable to supply these original accessories to the new owner, and this example for sale does not have any either. However, this CS80 does come with the original lid, which has been re tolexed of course. We will supply a copy of the owners manual on PDF.

This CS80 operates on EU220V but can be converted to US110V if required (subject to quotation).

We can have the CS80 professionally packed (custom crated) and shipped pretty much anywhere in the world (subject to quotation).

Price: With ‘average to tatty’ cosmetic condition, and fault-ridden examples of CS80 selling privately for £17,000+ GBP these days (if you can find one), we are inviting offers for this superlative & upgraded example in excess of £22,000 GBP.

Availability: This CS80 is now SOLD as at 9th August 2018.
