Hello, I have both a Sony D-555(actually 3 in all) and a Sony D-35 too.
I'm keeping 1 D-555 and the other two have(also the D-35 too) the
dreaded SKIPPING disease. One D-555 is my original one I bought back
when they were available. It is MINT but I sent it to Sony back then to
repair in Mahwah,NJ(no longer there, they moved to PA). The sent it back
in the same condition I sent it to them to fix(under warranty). It now also
lack Audio. I'm sure either of the ones I have up for sale are fixable if
you can find someone to do the repair(I wouldn't suggest Sony since I don't
think their capable).
The D-35 SKIPS on the first 4-5 songs, but then plays flawlessly the
rest. It has the custom semi-hard case with it and the original 3.2 Volt
battery holds a charge too! I have a Sony 9 volt/600 milliamp AC adapter
for it too.
If interested, contact me at : jrscpu2004@yahoo.com
I have a PayPal account too.
Let me know.
