I have a Roland D-70, 2x U-20 and D-10 that I am parting out.
one of the U-20’s is stripped down (no chassis) The D-70 is missing the middle section (2 octaves) of keys and is non-functional , the D-10 has a screen issue I believe. I also have a Bose tower amplifier section for salvage.
No reasonable offer refused
I run a electronics repair shop in New York State and am a registered business Q-Tronics message me if you are interested in any or all of these.
