Hi

Is the buzz there if you use the digital outs into DSP speakers, if not may work for DSP owners?
Perhaps you could test with cheap a DAC, if you don’t have access to DSPs.

More bad news Meridian don’t repair G68s anymore partly due to lack of spares combined with cost of diagnosis and labour to repair.
