There is no info given as to the nature of the voltage: AC or DC.
Two adaptors in series? The adjustable wall wart would have to be
AC to pass any current at all through the second one, but I've never
seen an adjustable

Huh? Think: two DC power supplies in series.

Okay, I finally get what the OP was talking about when he said 'series'. If
I understand, what he actually did was commoned one leg of the OUTPUT of
each device and used the two remaining leads as the output....

I agree with James. Try it on 24 volts (one adaptor: unfortunately, the one
he blew out), or else obtain a suitable supply (or buy a transformer and
build one). While what he's doing is not cascading supplies, it still
sounds like a recipe for disaster...not a huge disaster, to be sure, but....

At the very least, I wouldn't leave this kludge plugged in when not
attended.
