Voltage conversion from 220V to 110V.

Heres the specs from the unit as per their website......I dont see where it mentions the cycle. These are tube mono blocks. I would end up running a seperate line just for the amps because the rest of my system is 100V.

Output: 50W x 2
Output impedance: 4 Ohms, 8 Ohms
Distortion: <= 1%
Frequency Response: 18Hz-30KHz +/- 0.5db
S/N: >=95db
Input Sensitivity: 550mv
Tube types: EL34 x2/ 6N8P (6SN7) x1/ 6N9P (6SL7) x1
Measurements: 460 x 204 x 188 mm
Weight: 16 Kg x2 (gross weight: 19 kg x2)
Power supply: 220-230V

I dont think there is something as simple as a switch or pin the change it otherwise the seller would mention how easy it is to switch since this seems to be affecting his selling price.

Jea48...The "neutral" (white) wire in our 110 volt system is connected to ground only back at the fuse/breaker box. In the electronic equipment the input power goes only to the transformer primary winding which is floating (not connected to ground).

There might be a pilot light needing replacement or a dropping resistor. A schematic would help, but I doubt that you would have much of a problem making the conversion.

Jea48,

I use two hot legs and one neutral conductor. Since the line is a dedicated one I haven't had any hum problems. About the polarity, I guest that when I change the voltage selector switch the unit does make all of the necesary adjustments.

Some of the components use a Switch Mode Power Supply (Kairn-Pro & Ikemi), the others use a regular thoroidal
transformer (Klouts, Kudos & Av-5150). The transformers have dual inputs leads, my feling is that they are each propely wired(polarity) for each woltage. In my case it was easy, just had an electrician install the 220V line,
change the voltage setting on the units and replace the fuses, from 6.3A to 3.15A. Hector

Eldartford; yes I know the neutral is bonded to ground at the service panel only, and not at the equiptment.That could prove to be quite dangerous if it was connectd to the chasis.Just think what would happen if the plug on the equipt.was pluggeg into an old non polarized recept.with a ground cheater,and the polarity was reversed. You would have, ONE HOT AMP.You missed the point I was trying to make.
