Given the current recession, I was going through my parts bin looking for things to make up on the cheap when I came across the old Monica DAC. Looking at the board, basically it's a piece of junk - terrible layout, passive I/V (shocking for the TDA1545), generally a waste of space. It does...

Anyone know how to suppress the "helpful" message telling me one of my disks is full in XP?? it's exceedingly annoying! cheers g

There's always a lot of discussion about input high pass filters on things like CMoys, and I think it's to do with a lack of appreciation of the theory of it. I present my little introduction to this topic. I hope it will serve as a general introduction to complex impedance, and also be...

I was wondering if anyone could just check this little circuit. It's for a clay pigeon layout to provide some more options to the standard "on report" targets. So, schematic segment and then what I think should happen: 1) 5V to "INPUT" allows Q1 to conduct, and the R1-C1 to start...

Just been watching this, it's absolutely the best thing on TV just now join up, let's get bigger than Palau!! www.citizensrequired.com

Dear All, this is the OFFICIAL thread to sign up for the PCM2902 board. In difference to usual group buy setup I know the shipping cost, so there will be only one round of billing by PayPal. I can also take payment by cheques drawn in GBP. Shipping and fees will be £1.50 internationally, and £1...

Dear all; I posted in the For Sale forum a while ago about LM329DZs for Jung Super Regulators; Nisbeth volunteered, but for some reason DigiKey won't ship the LM329s to Europe. So, I was wondering if anyone ordering from DigiKey in the next week or two could throw me in 10 (ten) x LM329DZ...

Hi all, just a quick note to say there is a group buy on (hopefully) for CS8412s for use in Non-OS DACs. The guy doing it needs to order 80 by the end of the week, and I wouldn't mind a couple at that price. Linkage if you're interested http://www.diyaudio.com/forums/showt...8&pagenumber=1...

Well, to all a very happy Christmas (I'm dreaming of a white one, myself) and I hope everyone has a good day tis' the season to be jolly (fa la la la laaa and all that if you like ) Raise a glass to the good times, the bad times, and the unlucky people in this world. best regards to all...

Hi all, I was wondering if anyone could recommend me a reasonably cheap web hosting that would offer me the following: Email forwarding and/or POP3 mailbox Around 20-50MB of webspace FTP access Bandwidth of around 25MB per month Registration of the domain www.awjlogan.net Thanks, I don't...

Just thought I'd post a couple of pictures of my PPA which I've finally finished. Just to be a little different, I've put in AD797s instead of the usual OPA6X7 or AD8610. So far, they are excellent. DC offset is a little higher than I'd like, but it's only about 20mV, so I'm not too worried with...

I don't know if many people remember seeing my CMoy layout using the Panasonic EVJ and a TLE2426 railsplitter, but a fellow audiophile (not sure if he's here on Head-Fi) from the UK, Alan, has got round to building it. It came out better than I thought it would, and he's agreed to let me post...

Hi all. Just a quick note for anyone in Europe (or anywhere for that matter), that this PCB manufacturer: www.thepcbshop.com is the dog's bollards! Received some boards from them today, really high quality, very reasonable prices, and they've just upgraded their facilities. Subjectively, I...

Hi all. First of all, I know this should be in For Sale/Trade, but I didn't think anyone would see it there. So, could anyone in the States help me out in sourcing one of the Rean-Neutrik insulated jacks (as first used by Voodoochile)for me in the very near future? I found a source here, but...

Hi all, I was wondering if anyone had 5 of the MC33340 chips (as per PPA battery board) in a SOIC package? For those interested, it's for a small charger for the USB DAC or for any application for that matter, as shown below: For interest, it's 25.4mm square, the big component not...

Does anyone know exactly why this version of vBulletin insists on changing the number of days of posts it shows, and varies it for every level of the forum you go to? I tried changing it in the User Control Panel, but to no avail. Please help, as it's fairly annoying g

Evening all... this is actually AFAIK my first post in this particular forum, and I was wondering if anyone around here uses any of the Cyrus CD players? I don't hear them mentioned much around here, but they get uniformly good results in the UK hifi press, and What HiFi's recommended CD player...

Sad news for all members of Pure Class-A from the UK... I read today that Mr John Linsley Hood passed away yesterday; a sad day for British audio electronics and someone who contributed much to all our thoughts are with his family.. g

they seem to be turning up all over the place at the moment. Anyway, these guys have a huge range of Japanese transistors, perfect for a Gilmore Dynamic, and also some chips relevant for a DAC. I've not looked through too much, but that is a great start!! www.grandata.co.uk g

I'm going to start this thread for very self serving purposes. I've been looking to design a very small differential drive amp thats completely SMD apart from the power caps and pot. The problems come when trying to implement a cascode class-A bias into it JFETs are not really made in any SMD...

I was just wondering how many folk around here donate blood on a regular-ish basis?? I went for my second time yesterday, and I'm terrible with the whole thing. I don't mind needles, and it's not painful, but the mental picture of the thing gets me every time (big tube going up my vein)and I...

Hello, this is particularly directed to people with people with experience with this circuit (ppl, tangent, aos, peranders etc) I recently bought aos's board for this amp, and was buying components for it and found that the size left for the 120uF/100uF electrolytics were too small to...

Mods and anyone else interested. I was over on the Bit-Tech.net forum recently, and noticed that they had extra "sup" / "sub" tags for superscript and subscript respectively. This would be very useful and would make explanations clearer for a lot of things as well, eg, I tried to write Idss...

This is probably the best place to post this little request, it'll no doubt be buried in For Sale/Trade! So, does anyone have a set of end panels for a black Hammond 1455N1602 (the big one)? I don't mind if it's the plastic or the black(!) aluminium panels, just i found a mutilated one lying...

I was just checking out the Elektor Electronics (electronics mag here in the UK) website, when I came across a project about using the 2.3V GoldCap 10F capacitors as a battery with a long shelf life and ridiculously short charge time. It incorporates a switching power supply to provide 9V...
