hi Juke thanks for the pictures they are most helpful and show some nice soldering. hi mike I've done the belt off the mains a few times last time i was just checking the solder joints for mechanical integrity. oooooch put me in a bad mood for the rest of the day take care

Ouch.. A bit too close ! 230V is serious stuff to mess around with :S

I'm starting to feel guilty now. Mike making the amp for me nearly killed him!!! Jeez. Does that make me guilty of manslaughter? I don't want Mike's Mum shouting down the 'phone at me. I wouldn't be able to sleep. On the stone - 'killed by a Panda, he shouldn't have put his fingers in there.'That restaurant will charge me £30 for that ice. I hope they bloodywell deliver it to your door. It'll cleanse your palette before tucking into that black pudding.

That was a scary minute or two. Big of you to post your experience, make us all think, hopefully Ian's amp is looking superb. I have to say when you posted that you were going to use that LED and a toggle switch I thought it would look grim. Happy to admit I'm wrong. It gives the case a whole different character, like big brother to a Neco I'm using a Neutrik socket that I think would work really well with the other bits. Only have the one but its serial number is NYS220-3. It is chrome, I just shot it under tungsten to avoid flash glare. www.maplin.co.uk/Module.aspx?ModuleNo=223988&C=5716&U=shop_N39GB Syd

BTW... those sockets are good..... tried them a few times..... My favourite (of all time), though, is the Switchcraft (made in USA) ..... pure quality

Ian...... I don't want you to think you are obliged into giving the Panda a rave review and ask you to be BRUTALLY honest with me.... I like to hear it as it is...... A "no nonsense" 100% "as it is" appraisal... that's what I like Mike.

I hope to have it running off the right source tomorrow night I was only thinking of the solid SS look of the Neutrik, though its a good unit sonically too. Your Switchcraft's a good cosmetic match too. Syd

Here's a question that's been bugging me for ages... Mike, you always have your switches set to "down" as "on". I've always thought that convention was "up" as "on", I'm certainly more comfortable that way around, to the point of even turning my "Pinkies" switches the other way. Any particular reason or just preference? (I know some switches have their red tell-tale show your way so they have to be) Curious Chris

Chris Re the switch : That's the normal convention Downunder as well. Possibly in most British Commonwealth countries as well? Of course, those damn Yankees have to be different with their light switches too ! You guys can't even get the water going down the plughole to go the right way either ! Alex

Because it has FETs at the input, it will even have a little of that valve sound about it, but with balls ! Alex

What, tubes with balls ..... Sounds like I'm getting the full jobby. It also sounds like somethng else. Of course, those damn Yankees have to be different with their light switches too ! Yeah, I had to sleep with the light on all night when I was over there. Terrible, it was. I can't wait to get my ears on it. I think I'm lucky in that Mike's and my ears are pretty close. His descriptions of stuff pretty well match what I hear when I try it, but I don't want my X-Cans to be jealous. I'm extremely attached to them. I've really enjoyed watching the bag of bits grow - it's a real reference guide. Poor Mike works his socks off and nearly killed himself!! It kind of makes me really look forward to the amp while feeling guilty for the (almost) death of Mike ...... I suppose it's better than death by gorilla since they tend to get a bit amorous just before they do you in.

. if my finger had shorted across live and neutral I would possibly be typing this from Heaven (or more likely Hell) right now One small slip in concentration can result in DEATH so please ensure you have the powercord disconnected before working on the amp. Mike. Don't worry about being shocked that much. I have 'hung' on live wires a couple of times. Also got some shocks from TV voltages which run up in may hundreds of volts. I even survived a jolt from my electrostatics (3kV DC !) and was thrown several meters across the room. It gives you a nasty feeling and can be painfull for up to several days though. I know many engineers/repairguys that got 'shcoked' occasionally. Don't know (knew?) anybody being killed by it. from Wiki: Up or down The direction which represents "on" also varies by country. In North America it is usual for the "on" position of a toggle switch to be "up", whereas in many other countries such as the UK, Ireland, Australia, and in New Zealand it is "down." In multiway (hotel) switching, the correspondence between a single switch's state and whether lights are on or off depends on other switches in the circuit. In countries prone to earthquakes, such as Japan, most switches are positioned sideways to prevent the switch from inadvertently being turned on or off by falling objects. I'm with Mike.. all my switches point towards Alex in the on position, except the light switches with a single switch, these all point upwards.

Mike. Don't worry about being shocked that much. I have 'hung' on live wires a couple of times. Also got some shocks from TV voltages which run up in may hundreds of volts. I even survived a jolt from my electrostatics (3kV DC !) and was thrown several meters actross the room. It's DC voltages above 200V that have a potential of killing someone. AC voltages raely do. I know many engineers/repairguys that got shcoked occasionally. Occupational hazard. Never heard of anybody ever being killed by it. Frans You are so damn wrong with those statements, and I would suggest that RG members take extreme care when doing things like Mike was doing. You are however correct about high voltage DC where more than a few mA is available. A mere 5mA is reported to be enough to kill you with AC. When I was much younger I was thrown backwards and crashed into a wardrobe. It was sometime before I could answer my mother who heard the crash. Years later, I accidentally touched the uninsulated terminals of a transformer, and was once again thrown . My wife's daughter was badly frightened ,as I could not speak for quite a few seconds to tell her I was O.K. These types of shocks may not kill you the 1st time around, but heaven help you if you have a heart problem. Alex

Alex, You know how I love to be wrong about anything !
You (and I) still live don't we as do all the people I know that had encounters with live wires and other potential lethal voltages. And I know a LOT of these guys. I never stated anyone should NOT be carefull with AC or DC voltages. It's the way the few mA's run and where they run and the conditions that can potentially kill you.
Don't know anybody that ever got killed by accidentally touching the mains power. This doesn't mean nobody ever got killed by it.. I just do not know personally anybody that ever got killed by this.
I always tend to unplug devices I work on and discharge the capacitors that hold huge voltages. Sometimes I just forgot or was careless and got a firm jolt.
It's a Panda thread let's not drift here. To please you I'll make an official statement and we can leave this alone:
NEVER touch any wires that have voltages on it above 24V ! Hell... don't even touch the +12V car battery while leaning over a car touching metalic parts.

Frans Just before we let this get back on topic, there have been quite a few documented deaths of licensed electricians over the years in Australia that were killed by 240VAC . I guess they got complacent ? Alex

Never stated no one ever got killed by any voltages. I bet you more electricians died in car accidents then those that were careless while doing their job or because someone else made a mistake leading up to their deaths. Read what I said.. I do not KNOW anybody (personally) that ever got killed by electricity and know a lot of guys in this business.
We can go on giving examples and quoting facts all day Alex..
It's a Panda thread

I built a synthesiser in the late 70's and it gave me a jolt at a very inconventient time. It was hot and I was working naked. (Yes, with a soldering iron too!!!) The jolt sent me flying backwards and I felt as though I'd had a hit in the chest. I lay on the floor thinking, shite, I just died so I stayed there, thinking that it's not so bad to be dead after all. Quite nice actually. Then some mates arrived and found me bollock naked on the floor, holding a hot soldering iron!! I thought they'd be shocked to find a dead naked body and would jump to nasty conclusions. I was actually frozen for quite a while on the floor. (or baked - which froze my body) Never did that again.... and the so called friends laughed their socks off when I fully came to.

Just for Frans and Alex... Yep, 'cuted myself on primary transformer terminals and stood bare foot in a puddle with a damaged live mains running through it, that gave me a good jolt! (Song Krahn festival, Thailand)

Agree..
hurts like crazy.... I once grabbed a line transformer in a TV and 700V DC with nasty peaks on it ran through my finger and 'cooked' a trace of meat in my finger. That hurt for a month !! cooling the burn did not help at all.
really like this Panda... great picca !

You'll like the sound of this I think. I've just moved from the iRiver to the PC outputting to a MF V8 DAC, whilst I read up on DC offsets Looking forward to trying it with the dedicated music server PC later on, into the Buffalo. Its very promising, detailed and real guts and power. Its slightly warmer than my AK SCHA which can be very nice, to me, with some of the stuff I like. I'm looking forward to your thoughts when you get yours as, like you I also love the modified V2. If it got no better than this I'd still be very happy. Syd Alex Your explanation ties in with what I felt on Tuesday, I must be getting better at 'sound analysis' Syd

Hi Mike, couple of questions,
What is that little PCB that came with my enclose kit for!!, and what voltage is the LED, as i think i might fit a larger green one to my enclosure.
Thanks.
Mick.

If you are soldering in the nude, sweating a lot and standing in a pool of water then chances are you could die if you come into live contact with the mains.
I knew a nutter many years ago whose party trick was licking live and neutral with his tongue (this same guy used to steal womens underwear off washing lines) I don't know if he is still alive.
