Question about Samson Servo 120 Amplifier

1 Answer

Power input switch to 220V?

The back of the amp says that it can be used in the USA at 115V, or in Europe at 230V.
I got it in the USA and i want to use it here in China, where power is 220V.
I changed to the recommended fuse type, but they blow immediately. Is there some kind of switch I can use to run this here at 220V?? I opened the chassis and none is visible.

This is a bit of a guess, but a lot of "switching" power supplies are capable of using anything from 97 to 230 volts without using a switch to pre-set what you are going to plug them in to. That is a guess about why there is no switch, and if I'm right, it is likely that the capacitors in the power supply are...were...strong enough to survive with American voltage, but 220 is a bit too strong for their age. The repair requires parts and soldering.

I'd like to know the real answer if you eventually get it fixed. Please post it here.

How do I eliminate buzz?


Things to check:
1. With your multi meter, measure from left ground to right ground. What do you get? Measure from each input ground to chassis. What do you get there.

2. Get or make a pair of shorting plugs. Plug those into the inputs. Power on. Hum there or gone?

3. Turn the pre-amp on. Connect. Level of hum change with preamp on?

4 additional information. How efficient are your speakers? This is a big amp, high-efficiency speakers may show some noise, while low-efficiency speakers won't.

A trip back to the shop may be indicated, too.

Need a power transformer from 220input to 120output


What you need is simply a power converter device that knocks the power down for your device. Look for a UK (European) to USA power convertor on somewhere like Amazon.

My NAD C350 won't allow me to switch input source - permanently on "AUX". Any idea as to cause/fix? Also I need to switch out my power 220v power supply for 120 (US). Would appreciate guidance here as...


Can't help on power problem, but the other sounds like an IC has failed that controls input selection. If you are going to do it yourself you will need a circuit diagram to find the IC.

Pevey CS-800 old fuse not present. What is the correct fuse type for replacement. The fuse holder is on the back of Amp. Thanks.


Hi,

One of the latest versions has a 15Amp fuse at 115V.
If your CS-800 is connected to 220V, you have to use 7,5Amp (8Amp is OK).

regards,
Gerard

SA3 amplifier to move to Europe : capability of the transformer ?


While living in the States I purchased a Bose Acoustimass 10 system but have now moved back to the UAE. As the system operates on 115 volts ONLY I would like to get it work on 240V without having to use a step-down transformer. By changing out the transformer form 115v to 240v will it work or will I have to change any other components within the system. Can anyone help me??

Best way to use US-Bose SA3 amp in Europe ?


Bose say you should pay to get it converted because over time the slightly different power cycles can effect it, however it will still works fine if you change the voltage with an adapter - like I did!!!

NAD C350 stuck on "auxiliary" input


hey,

I have noticed that this nad c3xx series may have a general problem with the input switching chip. There are more post here on fixya where people have similar problems as you have.

For a few year ago, I repaired a fault that had close to the same symptoms, it was a cambridge azur xxx amplifier, in this cambridge it was a defect smd component that they used as a input multiplexer.

I look forward to repair this fault in the future. Nowadays i alway collect schematics and create repair e-books and/or repair movie guides in the fault finding process.
