Pinkie,

Hi - by curious conicnidence I need a 32V supply. What are the details for yours? Sounds like I should be subbing in the AD843 for my preamp and headamp ASAP. The latter is still with WNA

.

Regards,

Nick.

Yes I am interested in the composite's - it's one of the things I have been discussing with Dr White for some time. It would be great to have someone else checking out a few combinations too!

Sounds very interesting Mike. I'd like to try the AD 843s. I see no heatsinks in your picture. Does that mean you're running with the original QC settings? Any plan to try the AD 843 with the higher QC setting? Where did you buy the AD843s?

I'm not sure if he has got any adaptor PCB's for sale but will ask.... would anyone be interested?

I'd be very interested in buying a pair of adapters.

RS doesnt seem to stock the ad843 - any recommendations of where to buy it?

Nick.

 

[bludragon]

The ad843 appears to be available at farnell. I'm tempted to try it, but I'm wondering if I should try the 6171 without output caps first (but keep the input caps)...

Hi Alick,

I haven't upped the QC so no need for heatsinks. The 843's ran as hot as toast in the higher QC WNA but with standard QC they run pretty cool. I didn't buy mine, got them as a sample from AD...... not too sure if you can actually buy them in the UK

Mike.

EDIT: Maybe Dr. White can source them, must ask.

Hi Nick,

Mine is a 24V "calex" open frame linear PSU from rapid but you can adjust the output and, surprisingly, mine can be adjusted from 23V to 31.6V which isn't at all bad

I'll type more on the AD843 soon Nick. I'm, quite literally, sitting here swilling and spitting whisky and applying a frozen crumpet to my cheek in a futile attempt to kill the pain that's emanating from the "stump" of tooth the dentist failed to extract (half the tooth is still in my mouth with the nerve exposed) I was referred to the dental Hospital and they sent me an appointment for "September" so it looks like I'm in for months of excrutiating pain or will be appearing in the newspapers "Wild man holds gun to dentists head and demands an extraction" It's almost reached that point...... I can't take any more of this continual agony.... looks like I may be forced into going back to the dentist who made a pigs ear of the extraction in the first place and suffer further trauma from him wielding his chisel in my mouth.... he's more than happy to do it "immediately" as he's well aware that the original extraction was a total balls up and me appearing at the dental Hospital with a tooth in this state would not bode well for his reputation.

It's a case of suffering "agony" until September or going back to him tomorrow....... I've held out for two weeks but I can't do this pain for 4 months..... principle is out of the window, I can't endure the slow torture a minute longer.......

Whoops! this is the WNA thread and not the "state of dental treatment in the UK" sorry but "pain" is the only thing on my mind at the moment and the UK dental service is an absolute DISGRACE!! A dog with a broken leg would get first class care yet these dental butchers charge for the pleasure and don't give a flying screw if you're climbing the walls in agony as a result of their bodge up workmanship...... my crumpet has defrosted, off to get another frozen one..... will be fully active in this thread again once this tooth is finally extracted / ripped / chiselled / torn / beaten / smashed or power vacuumed out of my jaw (probably a combination of all of them knowing my luck

)

Hey Morrissey, do me a favour mate and change your lyrics to be more 2k2 friendly..........

Pain on the streets of London
Pain on the streets of Birmingham
I wonder to myself
Could life ever be sane again ?

Hang the dentist, Hang the dentist, Hang the dentist
Hang the dentist, Hang the dentist, Hang the dentist
HANG THE DENTIST, HANG THE DENTIST, HANG THE DENTIST
HANG THE DENTIST, HANG THE DENTIST
HANG THE DENTIST, HANG THE DENTIST!

You have my sympathies - the worst pain of my life was due to impacted wisdom teeth. They had to be chiselled out of the sides of my jaw bone after first being splintered. I had holes on each side you could put your thumb in after they both got infected!

My childhood dentist wouldn't give fillings (we later found out he couldn't rather than wouldn't) and made a real pig's ear of my dental treatment as I grew up (in a small town with one dentist). I suffered numerous abcesses and the like that really could have been avoided. He later got sued for multiple malpractice ad drove his car into the river to commit suicide. Fortunately when I was at college I got it all sorted out and I haven't had too many problems since then, bar some expensive replacement crowns when I first went to london. My advice is to see another dentist, get it documented and fixed and then get a good lawyer! I now use a scandavinavian dental practice in london - there come over here out of pity I think. They are cheap too!

I wouldn't advise crumpet - at least not for that particular swelling .

ad843 will arrive tomorrow...

Luxury! You were lucky to get them removed in one piece mate...... my L/H
wisdom tooth came out in one piece at the hands of my all time favourite dentist (a London based guy).... the R/H wisdom tooth took almost "1 hour" to budge at the hands of a Scottish dentist and he smashed the adjacent molar to smithereens in the process which meant I had to get it removed also "and" into the bargain all the teeth on the lower left side of my jaw had to be root canalled..... looking back that wasn't anywhere near as painful as this partial tooth with exposed pulp that's "sitting" in my mouth as I type this....... I dream of a "chisel" into my jaw at the moment, anything for a bit of relief .

A typical UK dentist then?

Did his patients stand on the river bank throwing ballast into the river to make sure he didn't surface? Sorry.... that was in bad taste.

He's the "only" dentist for miles around.......... seeing another dentist these days is almost impossible......... (and I'm talking private) It's a screw** disgrace........ what has the UK come down to?

Nah they didnt come out in one piece. It had to be shattered while still in the jaw and then dug out. It was buried under the back molar so deep under I didn't have a clue it was there. My face was the size of a pumpkin for a fortnight and I couldn't turn my head at all. It killed the molar roots as well - root canel surgery on both sides. Plus it took about 2 years for the holes to fill in. I had to empty out the "pouch" of pus and food after every meal like squeezing a tube of toothpaste.

Plus, I had to eat gravel straight after the operation and washed it down with broken glass - that's the meaning of pain! (cue monty python theme song)

You lucky bugger! I always wanted to go private and experience good treatment like that

Hi Mike,

Is there any chance you can do a quick comaprison for me?

Can you please compare the ad825 with the ad843?

The reason I ask is that I have been using the ad825 in the Jung regulators, and have found them to outperform the lm6171. I haven't got any ad843 at hand so I can't compare.
BTW ALW supplies jung reg boards for £5 each, they really are great, you won't belive the difference they make.

I have also tried peranders jsr-03, a little more expensive at around £8 a board, but they are even better.......


Thanks
Raja

Hi Raja,

Sorry mate but I don't have any AD-825's to hand so can't do a comparison between it and the AD843. IIRC when I tried the AD-825 in the MKl I wasn't over keen on it and ended up using the two I had in the rail splitters to get rid of them. You'd quite possibly like the AD-843 Raja, well worth a roll in if you can source them.

All the best.

Mike.

Hi Alick,

I should have a couple of extra pairs of AD-843s by the end of this month and I'll be happy to send you a pair to try if you like?

I'm definitely very impressed with them but I've been on and off and on again with quite a few things audio these past few months and It would be good to get a second pair of trusted ears to evaluate them in the MKll as I'm beginning to think my ears / head are getting in the way of the music.

I was at the dentist this morning to get the remainder of my tooth extracted and he suggested that my sinuses may be playing a big part in not only my tooth problems but also my taste, sense of smell and hearing....... along with the agonising (seemingly continual) toothache there's a pretty rank taste at the back of my mouth and when I blow my nose it smells like cow dung emitting out of my nostrils. I've never "knowingly" suffered from sinus problems but, the more I think of it, it's all starting to make sense.

Fortunately I had a Doctors appointment this evening and he had a prod around and reckons there is pressure on my sinus and sent me away with a nasal spray, some amoxycillin antiobiotics and he will be referring me to an ENT specialist.

All this "head" crap has only come on this past year but if It's all being caused by the sinuses and can be cleared up I'll be very happy indeed......... it sure would explain a lot and kinda makes sense if the Maxillary Sinus is infected..... that would affect the whole head and would / could cause problems like gum infection, hearing problems, loss of taste, headaches etc.

Hopefully I don't have an infection in my sinus (the bad taste, rotten smell in my nostrils, throat problems, tooth problems, headaches, loss of taste and general feeling of lethargy would suggest I may have) but until I can get it confirmed one way or the other then It's not a good idea for me to be evaluating opamps / commenting on them.

This Beclomethasone Dipropionate Aqueous Nasal spray seems to be shifting some of the blockage but I can't say "oh yeh the AD843 really blossoms once you snort some Beclomethasone Dipropionate up your nose..... the highs are higher..... the leading edge of the......." blah blah

And I don't want to attempt to pretend. I'm not hearing too good due to this bunged up head and am more than happy to send you over the 843 Alick in order that you can evaluate it in my abscence.

All the best.

Mike.


PS: Even with bunged up head the AD-843 came across as something special.

 

[Alick]

Mike

I'd be grateful for the loan of the spare pair of AD 843's when you get them, thanks. As always, I'll be honest.

In some ways, it might be good news if you have a sinus infection as it should be relatively simple to sort out and it might well be the cause of many of your recent symptoms. It would be fine if they all disappear after a short course of antibiotics (although, knowing your luck you'll probably turn out to be allergic to amoxycillin

. Start popping antihistamines if you come out in a red blotchy rash). And keep taking the Beclo, it should certainly help. Fingers crossed ...

Late thought; if you think that the AD843's sound good now, imagine how they might sound with your hearing optimised (if that is the isuue). Potential audio Nirvana looming?
