I have a Crosley CR66-PA. It's 120 volts and I

Pull the platter off and look to see if it has a bearing, if it does try and find a replacement for it.

Just wondering if anyone had an answer, how to connect external speakers to the Crisley CR66?

TRY THE SWITCH IN THE BACK , TRY IN BOTH DIRECTIONS !!

If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU. Before an explanation of how to do it you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 240 volt receptacles and if you plug any 120 volt device into them, the 120 volt device will be destroyed. That said OK, any 120 volt outlet can be changed to 240 volt by removing the 120 volt circuits neutral, re identifying the white wire with red or black phase tape and connecting it to a new 2 pole 15 amp breaker. The maximum that this circuit will now load up to is, on #14 wire at 80% = 12 amps at 240 volts. The 120V receptacle must be changed to a 15A - 240V receptacle so that 120 volt devices can not be plugged into it. Never use 2 single pole breakers together because code requires that on a fault trip both legs of the 240V circuit must be disconnected simultaneously. OR USED A Quick 220 Voltage Converting Power Supply
Voltage converter buying guide. Voltage Transformer Buying guide.Voltage converters also known as voltage transformers are devices that convert foreign electricity to power devices from different parts of the world. A step down voltage converter is a 220 to 110 volts converter. A step up converter is a 110 volts to 220 volts converter. Our 2-way converters are voltage transformers that convert power from both 220 to 110 volts and 110 to 220 volts. They also work with 100 volts, 110 volts, 120 volts, 220 volts and 240 volts. This model is a 2 way voltage converter / voltage transformer available in many different sizes including 100 watts, 200 watts, 300 watts, 500 watts, 750 watts, 1000 watts, 1500 watts, 2000 watts, 3000 watts and 5000 watts.

I have never seen a 240-volt window A/C unit for the U.S. market. So, my guess is it's 120 volt.

The best way to verify this is to read the name-plate on the unit.

Another way is to look at the plug on the unit's cord. There are at least three types of plugs :: 120 volt, 15 amp; 120 volt 20 amp; and 220 volt. 120 volt 15-amp will fit a standard household wall outlet. The 120 volt 20 amp plug is similar to a 120 volt 15 amp, but will not plug inot a standard household outlet. The 220 volt plug is altoghether different.

Crosley Model CR66 does not come on. It appears the transformer is blown out. anyone know the correct output voltage of the transformer? barely a year old.

it is sorry that the clock has been damged by high voltage so , it can not be repaired but you can replace the entire set
thank you

It sounds like you hav blown a fuse. Hopefully just a fuse, connecting a 110 to a 240 will hurt.
Most equipment survives short term high voltage but sometimes it just can't take it.
if it's not the fuse then it's very likely damaged the power supply which will require the expert help of a technician..
good luck !
Ps the 321 is a very nice bit of kit..

no!   It will be ruined if you try that.
