Checked the output<br>> waveform on my SB-610 scope, and it appears clean. The tubes in the mic<br>> audio chain are good, so I'm not certain what may be up. Seems as if the<br>> level should be optimal around 50% or a little greater, but not maxed out.<br>> <br>> Anyone have a suggestion where I might start looking?<br>> <br>> 73,<br>> <br>> <br>> Sandy AC1Y<br>> <br>> <br>> Alexander N.
