[Amps] Henry 3K Bias Diode -- High Idle Current

[Wally]

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 current?


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.
