Effect. Go read a dictionary.

It's a pity that you can't contribute anything meaningful to a technical thread.
Do us all a favor and remove the ground wires on all of your gear.

Actually, you're dead wrong. Let me suggest that you spend some time with that dictionary.
Many people have trouble with affect/effect. It's really no different than the misunderstanding that people have about ground vs neutral.
As you can see, no one likes to have their nose rubbed in their mistakes. It's a shame that as intelligent as you are, you didn't get that out of my post.

Hey Martin, take note: everyone needs an electronics expert to fix an amplifier but nobody needs a linguistics expert to fix an amplifier. Your commentary isn't even germane to the thread. You're in the wrong forum. You should be looking for a linguistics forum.

Stop and think about this for a minute -- when you attack an expert who gives out free technical advice, and you give him a rash of guff for taking the time to help someone, he gets pissed off, and then the forum stops getting free repair advice. You've just screwed everyone. Was it worth it?

Bye.

Unfortunately, in case you didn't know, every audiophile is an expert. That said, you should expect to be attacked as well as to take a lot of guff. Yes, we are human and we get irritated, but the decision to stop offering free advice is yours. YOU'VE just screwed everyone. Lighten up - life is too short and being jacked shortens it even more, not to mention the negative impact on your social life.

Be Cool. Enjoy the fun this hobby has to offer.

P.S. This is a test. What is the device pictured in your avatar and who developed it commercially? No fair cheating!

Not bad. It's actually spelled nixie tube, and they were developed by Burroughs for use in cash registers in the '60's, as well as being sold as components to other manufacturers for use in their own designs.

OK – the sunfire arrived! When I first looked at the plug that's sticking out of the lead-stub from the amp, I realised there actually *is* an earth pin – but that is seems to have been cut in half – or perhaps this type of plug is just like that. I got a bit animated with this, thinking I'd got lucky with a European union, bath/sauna-friendly version of the sunfire, but it wasn't to be. I opened up the plug and the wires coming from the stub are two thick black and white leads, there's no earth wire. I didn't feel like opening the box – maybe another day.

The good news is that the amp works and works very well. I've recently bought two pairs of monitors: Tannoy System 12 DMT IIs and JBL 4312As. I wish I had a different amp to compare with them but I don't – my other system is a pair of active monitors. Of the speakers, the Tannoys are the clear winners for me but the JBLs sound super nice, a less bass and a little harder to differentiate the instruments when compared to the Tannoys. Presently the speakers are constricted in a small space and are no more than a metre and a half apart – so the sound field isn't as spacious as it could be – that will improve when I move house in a month or two.

I'm listening to a few different things – so far a Schubert octet and a Bebel Gilberto album both on CD through an RME interface and the rest on vinyl – Ed Motta, Captain Beefheart's Clear Spot, João Donato, old mono LPs – lots in quick succession. The big thing I'm noticing is the dynamics – clear in the classical of course – but the Ed Motta was really interesting. He's a soul/jazz/funk musician who, in recent years, isn't using any compression on anything – voice, live drums, horns, nothing. I'd noticed this before on my old system – but with this, it's another thing altogether - very live sounding. The LPs are performing far better than I expected too – for me, no contest – I prefer their sound through this system and my pre-amp is very crude (the turntable is OK, a basic 'project' model).

So, I'm happy – although still unearthed and no doubt ungrounded....

Cheers,

Glad it arrived safely, and in working condition! \:D/

But to keep *you* and your loved ones, guests, etc., safe and working condition, you really should take the cover off NOW and let us know what you find in terms of connections to the chassis. Some pics would help, too!

There was much heated discussion on this thread, because electrical safety is such an important and complex topic. You can't listen to music when you're dead....

What kind of power outlet are you plugging this into? Pics would help here, too...

Safety first, always! I will sacrifice quality if necessary when it comes to safety. Foolish to do otherwise. But the funny thing is, usually when you do it all in the right way, you don't have to sacrifice the safety anyway!

Hey, trivial fact. On those JBL 4312's, the woofer runs unfiltered. It's a full range drive to it. And second trivial info, if you turn the pot on the face down all the way, you totally mute the drive to the mid. I played for a while with a stacked pair of them.

Since you're clearly the smartest guy in the universe, I'm sure you just put that there to see it we were paying attention.
