We assumed that this meant a DC amp, but we weren't sure. In fact, we weren't even sure what the advantage of a DC to an AC amp was. Isn't this term used to mean an amplifier which uses direct interstage coupling rather than using capacitors or transformers? The point of avoiding the use of capacitors and transformers is that they tend to act as filters, limiting frequency response. Audio gurus, is this correct? -- ========================================================================== Bob Parnass, AT&T Bell Laboratories - ihnp4!ihuxf!parnass - (312)979-5760
