Yes they can be!  I had fits with a home brew supply using 866's.  Went through
a bunch of them. Never could get more than a few hundred MA. And the darn thing
was never reliable on start up - blew fuses left and right.I swithed to 3B28s
and the probems went away.

Is there a more modern eq. of a 872?
