Hi All:

After several months of non-use, my Henry 3K exhibited a strange issue.

The idle current is usually around 200 mA with no excitation applied.  Tonight 
I noticed it was arounf 300-325 mils.

Loaded up the amplifier like normal.  Amp produces plenty of power, but this 
high idle current concerns me.

I wonder of the 10 Volt 1.2 Amp Bias Diode is shorting, causing a rise in idle 

Is this diode still made?  Still available?  Or is there a good substitute I 
can buy from Mouser, or will Henry Radio sell me one?

Let me know.
