Folks, this seems to be the last issue with this nice looking unit. No AM or FM reception, antenna or not- regardless of muting switch engaged or not. Also, when AM is selected, tuning meter pegs. I've lifted one leg of R66 (180ohms) and it checks good. It appears HA1197 (Hitachi) is responsible for the AM section, and it measures near 17VDC on every leg of the IC. Other than swapping IC's out (I certainly don't have any spares!), are there other things to look for on the tuner board? The entire unit has now been recapped, and I don't believe the tuner section was tested prior. All other threads I've read with these same issues had a number of BAD IC's that were the culprit. I never get components on eBay, but that might be the only option for these legacy chips!?
