Recently purchased a KR-4070. Got to love these old time tested units! I desired the manual control of the tuning with no digital presets.
Am going to use it in my shop.
Everything works great except the FM reception. On AM it will get signal strength of 4-5 and sound good. On FM it will only get a signal of 1 on the strongest stations and pickup 5-6 stations on mono and 1-2 stations on stereo.
What I have done so far:
Blew a small amount of dust from inside unit (no change)
Installed a nice GODAR antenna for the AM and FM(slightly better)
Tried a T shaped half wave antenna(same)
Moved the unit to the house(same)
The tuner definitely is not amplifying what the antenna is providing.
I have a strong electronics background an am more than willing to replace components to repair it.
Have the schematics.
Looking for someone who has great experience on the tuners and can steer me straight.
