Looking at the schematic I think there is an error in regard to C306. I think this is an intereference supression capacitor going from the...
For the wire I recommend 28-29AWG wire for replacing the existing wires. The exact diameter isn't critical as the current consumption is very...
I attach a picture of how the wiring is done. The 2 batteries are wired in series (to have 3V), so there is one black wire that goes from the...
Indeed the BA3304F is not the limiting factor as the closed loop voltage gain remains contant until above 30kHz. Looking at the datasheet of...
@Thomas Monteith If you're willing to send the device to Romania I can fix it for you.
There is a black lever underneath the center gear which needs to go into the slot of the plastic slider. That lever is not inserted where it's...
Unlike a 3-head recorder, on a 2-head recorder the head is a compromise between recording and playback. So the gap is not as large as on a...
I am looking for a counter for the SONY TC-D5 (any of the models as counter is identical). If someone has the counter or has a unit for parts,...
That is correct, when the switch is in the NORM position no EQ is applied.
I attached the NJM2106 datasheet. Please check pages 7-8 of the datasheet for specific details. Both cutoff frequencies and the gains can be...
MegaBass was designed to compensate for deficiencies in the frequency response of headphones used at that time. Especially on the ones that don't...
Indeed both WM-F5 and WM-DD use the CX891 not the CX20084.
C. Is the difference between the 2 heads audible ? To my ears while listening on Beyerdynamic DT900 Pro X headphones I would say no. Why ?...
B. Head swap Now, going to the head itself. Before swapping the head, I measured its DC resistance and inductance and the values are summarized...
This thread covers a mod of the WM-DD33 I did for @Emiel, as he wanted an improved DD33 in terms of sound quality. We exchanged ideas and settled...
3rd party adaptors can be found here: https://www.ebay.com/itm/224860934489 but won't look or feel as good as the original. Indeed that...

Vintage Walkman Lab is a re-seller, they don't perform any repairs (apart from a simple belt change maybe) on the walkmans they sell. But the...
This mechanism needs a new clutch gear, which can be found here: https://fixyouraudio.com/product/sony-wm-a602-clutch-gear/ The problem is...
The days of capacitor plague are long gone, nowadays anything that is a big brand (Nichicon, Panasonic, Nippon Chemicon you name it) will provide...
