Thank you for the link. I have no problem with using LEDs ![Icon_thumbup Icon_thumbup](https://philcoradio.com/phorum/images/smilies/icon_thumbup.gif)
Also thank you for the information about the muting switch. That jogged my memory that my 37-690 has the same automatic tuning mechanism. I have yet to do any work on it but think I'll pop the lid on it's tuning mechanism and do a little comparison.
