[HBR] Restoring old receiver

Sun, 3 Aug 2003 15:49:05 -0500

You are correct Hugo.....   The mica ones in the RF tuning section look
ok, but the wax paper and electrolitics are bad news The hum level is at
max no matter where you put the RF and Audio gain controls.  I think I
need to replace about 22 caps total. De stan

Every cap?
Do the mica and ceramic caps age as badly as electrolitics and wax /
papers
?
I ask this because you don't see too many old oscillators suffering from
bad
caps as audio stages do, for instance.

Curiously,
