I have a 1985 silver Sony WM-DDII cassette walkman with dolby B NR for sale, it is in fair to good condition, work great no clicking during playback, as center gear was fixed. rewind and forward works great to and sound good.

I remembered I seen you fixing a Sony WM-DD on youtube:

Strange this was cheaper than the WM-DD despite this had Dolby B. Are they differences in electronics?

No much, just one was not in the greatest condition so when cheaper.

Paste the links onto Google Translate (it's in Japanese)

In Japan, the WM-DD was cheaper than the WM-DDII. When I checked these two links, the specs are the same. Is this true? Thanks again for the big helps!
