<Mike needed this as a replacement cathode bias diode in an old
homebrew 8877 amp with 2600V on the plate.  Manfred's suggestion is
the more contemporary solution, but in any case a 50W zener is way
overkill. A 10W zener would work just fine, and these are still
available without spending a fortune.

## added note re series strings of diodes for bias.  The leads on the  1N5408  +
6A10  ARE the heatsink for the diodes, so keep the leads long.   Easy  to mount 
on vector board, as long as the holes are big, like .065+  to handle the .060 leads 
of both types of diodes. ( aprx 16 gauge).   Since we are talking about real low 
voltages here, the diodes can all be phys mounted in parallel..then  wired in series.  
Then it all ends up being a compact assy.
