Hi everyone!

I have exactly the same problem with a EH4800 NANO,
all SMD version with two LM13700 and two TLC2272 op-amps.

Has anyone cracked this one?

I found no relevant info (not even a schematic for this version)
elsewhere on the net so before i start removing and ordering
spare parts i thought it would be appropriate to ask other people
and see what they got.

My guess: a bad TLC2272 chip, the one near the pot and power plug,
but any of the other IC’s could be faulty as well.

Thanks for any feedback.

Regards
