Hello RScott. Welcome to AK. Found the Owners and Service Manuals here. http://www.vintageshifi.com/repertoire-pdf/H-Kardon-3.php .Clean the SW2 selector switch. Check the muting circuit. Muting circuit has a pot to set level of action.

Link was great but I couldn't find receiver on list?
There are two different HK670's the twin power receiver and an integrated amp. HK670 shows up on list twice but both are for integrated amp which is different vintage. Why would they name them the same anyway. Loyal HK owner since mid 70's as a kid.I have 60's tube amp, HK395i bought new in 84, AVR 535 new in 2002, AVR635 new in 2005 and now just bought this HK670 twin power for garage. Need to find service manual or advice as to where to find the SW2 selector switch is? Or the muting circuit? Advice very much appreciated!

Hi there,
Funnily enough, I have the exact same problem with my HK430 and posted about it a few minutes ago, before seeing your post. It's not the same unit, but seen their age they might have related circuits. Let's keep each other posted?!
Cheers.
