[Premium-Rx] R&D EK070 NF Blues

[Kai Garrels]

Hi,

my EK070 is giving me a hard time.

Sometimes when I turn it on, the audio is distorted or low not there at all, it sounds a bit like a loose contact.
Alle other functions including TEST are just fine.

Then after some 20+min of operation, everything is back to normal.

I checked the +12V voltage on the power supply which only goes to the NF amp, it looked ok.
The power LED is on, so I assume the other voltages are ok.

Does anyone had the same problem, or a good idea where to start?
Dry electrolytic capacitors? Where?

Best regards,
kai
