This Object

I replaced 12 capacitors with value outside tolerance, and two resistors. FM works very well, but LW is completely silent and MW is too insensitive.

After a few months of use, FM fell silent. After opening the radio I found the ECC85 to have turned white (photo), a sign that air has entered the glass envelope. I replaced the tube and the radio worked again.
