I collected my repaired K50 from Absolute Sounds here in the UK yesterday.
My USB output connector had worked free from the PCB and Pedro had repaired it as well as upgrading it to 5.0.2. So good to have a proactive distributor now!
Owners beware, the connector is a surface mount component, attached to the PCB purely by the solder pads.
The replacement USB PCB as part of the repare is an updated part where the connector is connected to the PCB via through - hole connection so ought to be more robust.
Mine is not the 1st unit he had repaired with this fault but the updated PCB should address this issue I would guess.
So, don’t be too forcefull when connecting your USB cable otherwise the connector may dislodge!
