Dear all, I recently bought a Rotel RC 1070 pre-amp. I have phones, CD and my tuner connected to it and running well.I was planning on using the last remaining AUX connection to connect my DVD to it. The interconnects are working fine but there is hardly any volume coming out of it until I push the volume knob to real high when I notice a little volume through.

30 years ago, when I worked at the Building Research Station we had some special drivers for shaking walls, floors and panels. The driver was like a heavy metal weight (about 10kg) with an arm projecting from it and also a cable for the driving signal. You bolted the arm to the panel and when you applied a signal to the cable the driver shook the panel using its own mass as counterbalance. It...

Hi guys/gals Here's a tricky one for you. I'm looking for a BUDGET audio amp that can be used to power an old pair of Mission 732s for a special purpose. Combination would be used to run an Ipod, via mini stereo jack and RCA cable, as my wife teaches Tap Dance and the current PC speaker set up (Creative with sub) is not man enough.

Akai EA-M830 Manual Does anybody know where I can get a free operating manual for an Akai EA-M830 Sound processor please? PDF format would be fine. I am out of work and not earning, which is why I cannot really afford to pay for it.

Following the death of a long time hi-fi passionned person, these speakers are for sale. He was an electronics engineer, and he designed and made himself. They have been working great for the past decade but obviously we do not guarantee their future operation. There are several hundred pages of documentation, but incomprehensible for the rest of us mortals. The speakers are the best of what was...

These are modified from the "Suzy Chang" design. The aim was to fit Fostex FE107e drivers into enclosures with a small footprint and limited height (they have to stand beneath a window). The original design is for FE103 drivers so I've resized things a bit. The woodwork has to be done outside... www.mixpix.batcave.net/1.jpg Some delay in getting these pictures ready. At the moment the WAF is...

I have being playing around with plate characteristics graphs, looking at how basic parameters (gm,rp and mu) vary with operating point. The most frustrating thing about this is that the published curves all extend to rather large plate currents and voltages. For my preamp I am working at plate currents of less than 5mA and the curves here are rather cramped. Is there any source of curves...

Looking for a CD to play this afternoon, I picked out The Trinity Session by The Cowboy Junkies, something I haven't heard for months. The sleeve notes say it was recorded live on 27th November 1987, exactly twenty years ago today. Coincidence? I think not! -- Eiron.

Well? Did anyone here see the concert? It would have be excellent, if what I saw on TV is a guide. I saw them in Sydney, back in 1971 (or 2, I don't recall). It was a most excellent concert. Trevor Wilson

I use SonicStage to put music on my MP3 player, but notice that some long classical pieces, though unbroken, have track numbers partway through. When I replay these pieces through my MP3 player, there's a very slight hitch or gap when these track numbers come up. Anyone know how I can solve this problem without resorting to a different CD ripper? I do find SonicStage very easy to use, for...

The old (Shure) cartridge I use has two clear holes for fixing it into the headshell of the arm. The actual headshell has one clear hole. So I also have an adaptor plate which has tapped holes. (Or nuts in captive slots. Can't recall which, and they are hidden in use!) I have been looking at modern cartridges and noticed that it is common for them to have blind tapped holes for fixing...

Overture3 has a built in subwoofer with its own amplifier. Excellent sound and sound stage. Wife wants to redecorate and this speaker is too large in the scheme of things. west westleyATgteDOTnet

Hi, I have a Denon analogue tuner and an an old (but excellent) AR amp. I have acquired a Sony XDL 40W3000 LCD TV and a Sony HDR with Freeview which I can play though the amp. Both the later of course give digital radio reception. My question is which one(s) to go for in terms of quality for listening to the radio (particularly classical music) Thanks Gordon

Does anyone know where I may buy a replacement battery (or one of alternative spec) for my FM4. My tuner has been laid up for about five years and no longer holds any preset stations. I read somewhere that it's rechargeable but mine no longer holds it's charge. It's marked on the cicuit board as M12615-3

Very rare DAC from this innovative French company (still going!). A wonderful sound. Was about £1200 new. Selling for £290. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=180190118657 Thanks for looking.

Hi I've recently created a Google-group for the original Cambridge Audio HiFi. http://groups.google.com/group/vintage-cambridge-audio Currently there's the complete P50 Service Manual (80pp) - which covers all 3 types. There are also circuit diagrams/manuals/reviews for P50/P60/T55/R50 - the list is being added to.

Is there something / a unit of somekind that I can hook up to speakers that will receive music either wirelessly or bluetooth from a transmitter ? I mean if I already have a stereo of somekind it would be great to plug in to the stereo a trasmitter, then locate any speaker setup / system around the home with receiver devices. Is there such a thing?

I'm looking for some closed headphones in the sub £100 catagory. I would like to be able to use these on various devices so I'm looking at 64 Ohm or less really. I was thinking about a pair of Sennheiser HD280 Pro as they seem to have good reviews although I have read that the bass is a little weak. If any of you guys has had any experience of these and can offer comment I would be...
