Dave!
I thank you for your reply, because reading it someone could learn some important things! However I restore electronic devices, american vintage juke boxes, Hammond Organs (I have restored an incredible Hammond Novachord too), radio and television sets, and a lot of more since at least 35 years!
I'm aware that there are problems about the conversion of the 220 Volts 50 Hz that we normally use, in a 117 Volts line, and I know the differences that there are in transformers for a different frequency. However the transformer was already burn out when I bought the CTC5. Of course I connected the tv set powering it to 110 Volts, (also if in that moment the frequency was 50 Hz), but it was already well cooked! In my laboratory and also in my home, every electrical plug around in all the rooms, has three different plugs, with 220, 160 and 110 Volts. I use the 160V line only for old household electrical appliances or for keep not too hot the soldering iron. And I normally use 220V and 115V for european or american devices. In my home I have a AMI I juke box from '58, my Novachord Hammond from '39, two Hammond organs from '35 and '50, a Parkhurst Zenith tv set (that in my icon) and more, all permanently connected to the 115 Volts line 50Hz. Where the 60 Hz are essential (Hammond Organs with tonewheel generator) I use a 50-60Hz converter inside the organ. In other devices it is not essential, because 110V are not too high and where there is a motor with rubber pulley, I have extended the diameter of the motor pivot .
Thank you!
