I've picked up a couple of penta amps.  Unfortunately, someone cut the power cords very close to the base.  My question is:  when I replace the cords and solder new ones on, is there a certain way they must be put on?  Here in Canada we have polarized plugs, does this make a difference, or is it not important which side solders on to which side?

Hi Guy,

My usual advice with power cords is: "Don't solder them!"  The high voltages involved mean that you need to be certain of a good connection and suitable insulation to avoid the risk of fire or electric shock.  Replacement power cords are readily available (Admittedly, I am biased here, because I sell them!) and the safest option is always to replace rather than to repair.

However, if you are competent with a soldering iron and you are willing to accept the risks involved, I can confirm that the 2 pin "figure of 8" power cords can be connected either way without a problem, as the amps have a transformer and rectifier that will produce the correct internal DC voltage whichever way round the power cord is connected.

Let me know if you need any help locating a replacement cable.

Best regards,

Steve.
