Hello! Happy New Year!
Tascam UH-7000 that I own shows noticeable interference from its' power supply unit. Mostly the left channel is affected (when an analog input is used with higher gain on it).
The internet search gives an advise to swap the STR-A6252M PSU controller chip (67 kHz) with the 100 kHz version - the STR-A6259H.
I did this but the noise level only increased.
Where can I find an official PSU schematics? Are there any PSU mods recommended by Tascam or the community?
Thank you in advance!
Warm regards,
Anton
