Need a source for a 12-14volt AC power supply for switch motors and uncouplers. Don't want to use a train transformer as it too easy to change voltage.

If VDC will work there are plenty of fixed voltage "wall wart" transformers around. I use a 12 VDC wart to power my 17 Tortoise Motors.
Just use the fixed voltage taps of any appropriate train transformer.
OR, use the programmable accessory output of a CW-80 for the most flexibility and fine tuning, with a full 5 amps available. The CW remembers the setting indefinitely, until you reprogram it.

Some people use those low voltage light fixture transformers made by Malibu and others. They are 12 volt with various wattage. Home Depot sells the 120 watt unit for about $60.00
Here's a 60W 12VAC transformer for less than $20 shipped.

That's what I use...acc output from CW-80. BTW, I tried using the adj output, but on my layout for lighting I could see the brightness wavering. With the acc output at the same voltage, the light was steady. Curious...sort of.

I use the K-Line Power Chief 120 watt accessory transformer. It has multiple voltages available from 3 volts up to 20 volts.
