1970s Yamaha YC-20 electric organ Made in Japan

Description

 It has a direct, thick and strong sound like an electric guitar that directly touches the sound unlike digital synthesizers or digitized organs (personal opinion). Unusual blue design. Antique 70's combo organ/electone.  Yc-20 List price at the time 125,000 yen Body size approx. 101 cm wide, 52 cm long, 18 cm thick, 27 kg, height approx. 85 cm when standing up. I liked the appearance and tone very much, but decided to dispose of it due to room redecoration.  The paint is in good condition overall, but there are some minor flakes (see photos 4 and 5). Also, there are some burn marks on the keys, probably from the previous owner smoking while playing (see photo 6). Please check the photos and refrain from buying if you are looking for a perfectly beautiful item.  Note 2: When the Balance knob (Photo 7) is turned up, a howling noise is heard. I think it is a knob to mix or switch the tones of the faders (like a graphic equalizer) divided into "I" and "II" (I when raised, II when lowered), but I basically left it low (II only) because of the noise it generates. However, even with "II" only, it is possible to change the tone to a certain degree, and I personally did not mind using it because I could produce the sound I liked. I would recommend this product to those who have the knowledge of repairing electrical systems. I found on a certain website that a simple cleaning of the inside may fix the problem, so I tried to open it once (Photo 8* several years ago), but I gave up because I was afraid to touch it due to my lack of expertise. Other knobs, volume, pitch, bass note adjustment, vibrato, percussive (rightmost green knob), etc. worked fine. Please understand that this is an amateur inspection.  PS: There is a pedal attached (stored in the same place as the power cable). It looks fine, but please understand that it has never been used and has not been tested.
