I thought I could match it to my 604 but found later it has 200ohm output impedance.

Now I need extra impedance matching transformer...too bad. And I thought what if I just connect the speaker to the amplifier. What will happen to the amplifier or to the speaker? Just curious.

Yes, you can use it with the 604s as a 1-WATTer. But you have to put a 250mA-Fast Acting-Fuse in the speaker-wiring. The sound quality should be good, as you are almost in a 'constant-current' kind of a situation here.

Actually these 'ohms' things are simply one of the ways to get the full power from the amps. This amp seems to be a 20 watt one. So, at 200 ohms load, it will give 63 volts at 315mA of current. Now this 'current' is the limiting factor as it depends on the gauge-no. of the output winding in the trafo. So 315mA is the highest amount of current which can be drawn. Now a 16 ohms load at 250mA will give 1 watt. The voltage (63volts) is not an issue as it depends on the volume-control setting.
