dear modi,

just wondering if the VT60SE we made before, does the tubes need to be biased every now & then? If so, when is the time to re biase the tubes?

換了大膽後要調較中點電壓至約46V。[/quote]

Hi modi,

Do you have any diagram of the circuit that can show me where to measure the bias voltage? You can email me the diagram if you have.

Thanks again.

Aaron
