Hi Art,

FWIW I don't think the spkr is orig & it wouldn't be a good idea to try
connecting it to the radio. The radio outputs hi-z & the orig spkr has
an xfmr to deal with it (to the v/c z). It looks like the Quam in the
pic has a bracket that once many have held an xfmr, but the style of
the orig cab is very similar to the HRO-5 series & not what's depicted.

It'd be a good idea to show the front (panel) of the doghouse supply &
a readable pic of its tag, too. The FB-7's supply was commonly shipped
with the 2.5v early sets.


That spkr had a transformer a one time. Look at the bracket.
