Have an unhealthy interest in vales and valve equipment. And even though NZ is 240v i have tried most of the McIntosh amps from A116 and later. So I know it is great to find the manuals etc that came with old stuff.While checking a 10" LP from the 1950s {Yma Sumac} a pristine card for the C8 Compensator fell out......so if anyone has the C8 and wants the card I can mail it to them. Only charge will be the postage.
