Truetone 1 Spot 9V/DC

Update: I had already switched to other power supplies such as Voodoo Lab and lately Cioks, which are both excellent products. Therefore, I never used the Truetone for about 4 years and it was staying in its original box.

So, I decided to sell this and just tested it. It was dead again. I think it's not even close to being a reliable product. Thomann offered a new product even though the warraty was already expired. Thomann is the best of the best, thanks so much!

Overall, I don't recommend anyone who is looking for a reliable power supply. This is not it!

My original review:
I bought this along with an ENGL Cabloader to use with my ENGL E570 preamp. E570's built-in speaker emulation is pretty outdated as you can imagine.
So Cabloader was definitely an excellent choice. However, a couple of days later, either Cabloader or this adapter stopped working. I wasn't able to troubleshoot the issue as I didn't have any spare adapters.

I had to return both items and Thomann sent me new ones immediately. (Thomann rocks!)

This time, everything has worked so far, no problem. However, I noticed the adapter was generating a hissing, almost like a sine-wave sound when plugged in. This sound comes from the adapter itself, not from any sound source.

Also, there is a lot of noise generated when used within the system I mentioned.

I must say, I have fallen for the user reviews with high scores.

For this reason, I'm giving this item 3 stars. I wouldn't recommend this adapter personally.

I have already ordered a Voodoo Lab Pedal Power X4 instead and will definitely publish an article with proof of my claims about Trutone and do a comparison.

Once again, it's been proven that you should invest a decent amount of cash in this kind of equipment.

For the past year and a half, I have been searching for an DC Plug for an old keyboard to use in the eu, ( I had been given not the correct one from original owner).

I had looked into transformers etc, but they were expensive for what I needed.

Searched on Thomann and found that they had The Truetone DC plug.(yay). It was The correct tip end and voltage. My search was over!!

The DC Plug works well. The length of the cable was more than enough for me; for some though, it may not be enough. It seems robust and well made. Time will tell. For now there are no problems.

If you have an old keyboard like I have with a 9 v + centre - polarity, this Truetone DC Plug, I can recommend highly. Job done!

As ever, Thomann delivery has been tops. Thank you Thomann!! I now have an old keyboard that I can use again.
