Reamping will kill me....really!!!!!!!!!!!!!!

[TonyS.]

:Smokedev:

Hey guys,
today my order with a radial x amp, rmp pro and a daccapo arrived.
I was comparing the 3 boxes and after some reamps I wanted to test the x-amp one more time.

This was my fail......when I messed arround with the gain stetting and lift/ground knob, my amp dropped out and I got a fucking heavy electric shock. from the metal case of the x-amp.

WWWHHHHHHYYYY? After the shock the amp turned on again.

My chain: Focusrite Saffire 56-->Radial X amp-->Engl e530-->Engl 840-->4x12
Before, I did some reamps with this Chain: Saffire 56-->Xamp(or the other 2)-->Blackmore / e530 ----effect send---> LineInput Saffire 56

I was suprised that this chain was very noisy, whereas the boxes were on lift-mode.(especially the first output of the x-amp)

Can anybody of you help me to find the mistake, please? Im feared of killing my amps or me.

Hmm some kind of weird grounding issue. Does your preamp/poweramp have ground lift switches on the back?

 

[TonyS.]

Yes, the poweramp from Engl...Its on ground...The grouding issue should also be the reason for the freaking noise....sometimes I heard, besides the 50Hz tone, a click/ cracksound.

 

[Wolfeman]

Honestly I wouldn't know where to start looking for the issue. So many variables. But from what it sounds like, when you touched the case and got the shock, you drained all the power caps. That's pretty bad if that's what it was. I don't think you got a whole 500v, but it's still scary.

 

[ahjteam]

I would see if you get the same problem with just the x-amp and then if you get it just from the amp. remember touch the cable end with the back of your hand, because your grip is really powerful when electrocuted.

Hey in germany we have 230V and I think this was the full voltage...got a a few schocks at work...

@ahjteam

I will test....but I dont think the reason is the X-amp. I hope its not the interface.

 

[TonyS.]

Forgot one more crazy thing.

-----> I just took the cable between Xamp and Amp out of the Xamp and was able to get the sound of the interface without physically connection!!!!!!! I was able to hear the guitar in a "good" level, just while holding the cable with a distance til 10cm to the box!!!!!!!!!!!!!!!!!

Hope you understand what I want to say!

call me old-fashioned, but isn't it safer to test it with a voltage meter?

@Wolfeman: how could a grounding issue lead to this? where does the voltage come from?

 

[Wolfeman]

It could be coming from the wall, from one of the amps, who knows. If an electrical path likes you as the ground better, it will make you the ground, so to speak.

I took the E530 completly out of the racks und used it aigain with daccapo and x-amp. No problems by now...also suprised about the cheaper daccapo....its much quiter and very clear. Expensive Xamp vs. daccapo --> daccapo wins.

Tomorrow I will test all the other rack/amp gear of contact between a conductor and live wire / case.

Will report.

 

[deLuther]

And how about daccapo vs ProRMP comparison (because it`s passive units)?

 

[John_C]

bear in mind that if there is a problem in any tube device it is perfectly possible to not find a short between live and earth and still kill yourself. The voltages in a most tube amps are in fact higher than mains voltage

 

[TonyS.]

And how about daccapo vs ProRMP comparison (because it`s passive units)?

Its the same...I think the X-Amp ist just active becuase of the 2 outputs.
The noise of the ProRmp was similar.

 

[deLuther]

Will you post some comparison clips in the future?

 

[TonyS.]

Sorry not much time yet.
I did the test yesterday and wraped the other boxes, allready. But when it helps you, I couldnt hear a sound difference all in all, it was just the reason that the radial producst were a bit more noisy! So why I wouldnt chose the cheaper Plamer? ... maybe becuase I can use to amps at the same time with the X-amp. But then I also could buy a second Palmer. It would be cheaper as well!

WTF!? be careful man...

 

[bryan_kilco]

Yeah umm I wouldn't keep fucking around with this gear if it's shocking you.....something is wrong.

 

[TonyS.]

I think its about the Xamp....no problems with the Palmer yet.
Doesnt know that Radial build equipment for hitmans.
