1984 Aspencade radio volume

[Cornhusker Joe]

I have an ancient Aspencade that I still enjoy a lot. I have a radio problem - very little volume either through the speakers or headset. The mute button works fine. Does anyone know how to troubleshoot the problem, or suggest most probable solutions, or a good source to turn to? I understand that this is quite old, and little activity with these old Wings, but I'm old too. I bought a '75 used in 1980, then moved up to the 1200. I own other motorcycles but the old Aspencade has hauled me for 180,000 and I would really like to have my radio volume back as my hearing is going downhill with age. I usually use headset in a full face helmet.
Any help would be appreciated. Thanks.
