I recently had two WM-D6 units that showed similar symptoms. Both units had CP601 repaired per @Deb64's prescription. They both looked to be...
[ATTACH] I recently had to debug on the CP602 work (and reconstruct pin 2 using external 47kOhm resistor due to loss of plate on the board) and...
It might be simple issue like white wire detached from the post around C610 - I recently fixed a CP602 but it ran still fast. I had hard time...
There's no reason to replace the existing one with MT3068 since the original one works well and seem to be power efficient enough. When original...
Unfortunately the above suggestion modifies the volume control for both headphone jacks. To add impedance to just one headphone jack, we could...
Problem statement: I have headphones and earbuds that are very high efficiency (due to low impedance maybe), and my WM-D6 is basically too loud...
Some test from WFGUI -- I didn't have 3khz test tape. So I recorded using WM-D6, then replayed with it. So, the measure might read like 1.4 x of...
Thank you @Valentin for the reply. I will try WFGUI but will need to revive one of my dead Windows laptops first ;) -- my journey of correcting...
I've been trying to improve wow & flutter of my WM-D6. On a certain recording (that I use WM-D6 to record then play) I find pronounced vibration...
