[TenTec] Mod for Century-21 hum?

[W8KEB]

Ken my Century 21 has the hum in the headphones.  I do not know if the hum 
can be heard in the speaker as I always use phones with the C-21.  I use the 
MFJ-392B Headphones which have an impedance of 32 ohms and each phone has a 
volume control.  With my eight ohm Yaesu Headphones I get the HUM and can 
not control the sidetone volume, the sidetone can take your head off.

It seems the MFJ-392B with volume control and 32 ohm impedance control the 
hum and sidetone.
