Default 2x9V and 200VA xformer, what to do?

As the topic says.
I just found some cheap xformers with dual 9v windings and about 200VA each. Is there anything fun to do with these?
Anything goes.

best regards
Ken

Get two of the transformers. Take one transformer and put the windings in series to give you 18v @ 11 amps. Then do the same on the other. That'll give you 25 VDC or so after rectification. Perfect for a LM3875 gainclone, or even better for a LM3886 or LM4780 (paralleled) into a 4 ohm load.

Then make yourself a nice 6 channel home theater amp Or just have massive overkill for your power supply.
