Conversion

[ledzep]

I have been offered a Denon dp80. It comes with a step down transformer but the transformer is noisy sounds like its vibrating the whole metalwork case. Is there a way to convert the turntable to 240v? TIA

I guess it's a Japanese model that only takes 100v hence you need the transformer. However you could take it out of the deck and put it in a box down on the floor where it won't vibrate and cause noise problems.

You might replace the transformer if there is one, or reassemble for 240v if a smps, but to start with a vibrating turntable seems the wrong way round?

Depends...

Japanese mains voltage (assuling it's a JP market turntable) is 100 volts at 60Hz. Some turntables (I don't know the Denon) need the correct mains frequency to work properly. It's also possible that the step-down you have is intended for US voltage, so at best it's 120V. Assuming the TT is happy with 50Hz not 60, then just look for a better step-down transformer, suitably over-rated for current delivery. A transformer running correctly ought to be totally silent and free from any vibration. If it isn't, then it's either faulty or being loaded beyond its sensible capability.

The Denon will be fine with either 50 or 60Hz but it will need 100Vac - I don't believe it can be converted to 240V. Its power consumption is a measly 8W so it is highly unlikely that the step-down is being over-driven unless it really is impossibly tiny!

The two most likely possibilities are that there is a fault with the motor unit so it is pulling too much current, or the step down is knackered.

A new 50W step-down can be had for £39.00 from Airlink Transformers so as long as you can confirm the deck itself is OK and not making any untoward noises, and the racket is definitely coming from the step-down, then there's no reason not to go for it.
