Astro Electronics Mach 300 I have bought this amplifier but cannot find any information about it if anyone can send me a schematic or info if possible it would be appreciated. It has 4 6lq6 tubes in it and works great.

Thanks Jimbo

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
