DD9 and DX100 are the 2 auto reverse units of the DD line. Somehow a column got hidden when I created the table in the first post, I’ll correct it...
Thanks Valentin. I'll leave the DX100 as I can't find another Sony unit that uses the DD mechanism to indirectly drive the capstan flywheels. As I...
@CDV: what about this layout? I used the eyedropper to copy the exact colors you used. Since I moved the WM-2 and WM-5 below the DD line, I...
The mechanism features the DD system: the disc driven brass rotor (bottom right) is driving a belt that takes care of the rest of the mechanism....
I used that to indicate a very likely relation, but without real proof points. Not the same mechanisms but close, or not true matches in the...
Thanks CDV for the review and improvement suggestions! I am looking at the genealogy tree picture, and there is no link from TC-D5 to the DD....
Did you also test the RTM C60 and C90 cassettes? I bought them a while back after some unpleasant experiences with vintages cassettes that had...
From a motor, playback head and current draw perspective it seems to be very closely related to the EX612.
Look at the DD9 service manual and the mechanism. It is amongst the most complicated in portable cassette players :) And still has 2 belts.
If started to go through service manuals to determine which models are affected because of the clutch. The WM-EX3 service manual I cannot find. I...
Thanks @Machaneus . I will update my overview to include both designers for the F5.
The DC2 is indeed the most efficient. Per my DD overview table, the DDII, III, 33 and 100 are more efficient; these lack Dolby C and the amorphous...
I would like to add: - direct or disc drive mechanism, auto reverse for low and stable W&F in both directions. Best seems to be DD9, but that is...
@Machaneus : can I conclude from the following paragraph it was Ichiro Hino that designed the WM-F5? After this, he designed the My First Sony...
The Eneloop Pros I have don't go above 5V if I recall correctly. These are great, above 2500mAh each. I have read good reviews of the IKEA LADDA...
Indeed a nice layout and with these type of buttons (feather touch), only possible with full logic capable devices. Similar to many other Walkmans...
Here you go! The EX508 is actually not that close of a relative. It’s mechanically upside down compared to the others photographed here and has...
Shall I post EX508 and 512 pictures as close relatives? Real party ;)
It looks like other brands like Sanyo had a similar configuration, although not marketed as bi-azimuth adjustment:...
Success @tomtom87 ?
