Probably a bit low for a spark-gap coil. Would work dandy on a
tube-powered coil. You stated (I think) that you have two of these
transformers. If so, try connecting the secondaries in series, but
keep the center-taps isolated. (Don't connect the grounds together.)
This will give you 5000 volts, which can work on a spark-gap coil.
Best bet is to use a multi-element series spark gap and set the
individual gap distances to maybe .010" or so.
Be sure to put chokes and such on the high-voltage leads to
protect the transformer windings.
