Herbert MK1 problem -solved-

Hi,

Everything on my Herbert works normally except the channel volumes for channels 2 and 3 - the volume works for channel 1. Does anyone know what the problem might be?

Many thanks!

Sorry but it seems you need a tech. Where are you located ?

Best regards,
Peter

False alarm! I think what happened was: I had a preamp valve fail quite late at night and by the time I had identified and changed the right one, I had to have my master volume so low (live in a shared house) that the channel volumes appeared to make no difference when I turned them. Today at normal master volume levels it's obviously fine - and sounding incredible as usual. Thanks for the help anyway, Peter!
