Hallo,
i am in the tuning process of this nice sound box. There are a few problems i can´t solve:
I have built in I/O Transformers, no Hold mode, Switched Attenuators for Input/Output levels. All switches work like they should so far. And it sounds nice!
1. But in bypass mode, the right channel is about 5 dB lower then the left one. I checked components and cabling in the output section.
2. I could not level match both channels for all three modes. Once i matched it in THD mode, in Comp mode there is a 1-2 dB difference (right channel lower).
3. I could not match the second harmonic in both channels. Whenn i match the overall levels to the same level in both channels, the second harmonic in the left channel is as high als the third harmonic, where in the right channel the second harmonic is much lower.
Maybe someone had the same issues.
Thanks
Thomas
