Nutone IMA4006 intercom shows clock/tuner but no audio
Hi!
It's been a while.
My sister's intercom (Nutone IMA3303) has a main station that is showing an accurate clock and doing fine with showing the radio station. But I hear nothing from the speaker. I go to the base station and nobody hears anything. Before I spend time on the amp board does anyone have an idea if something else is awry?
THX and Happy Holidays!

More than likely it's going to be a problem on the board. If it's fairly old the capacitors have dried up with age. I'd start on the board by checking power supply voltages.
Check the speaker for continuity too.
