Any recommendations for multi-channel audio editors? Most of them seem to only do stereo. Given a 5.1 soundcard it would be easy enough to prototype active crossovers by taking a stereo wav and filtering it into 5 channels: left and right highpass for the tweeters; left and right bandpass for the woofers; summed lowpass for a sub, with appropriate delays. Of course a Behringer DCX2496 would do...

I am designing a mic pre based on three 6AU6 tubes. The first two are operated as triodes with no NFB with an overall gain setting pot divider between them and the last is a cathode follower. I have discovered that by judicious selection of the component values in the CF that the predominantly 2H distortion of the first two stages can be reduced by a factor of 10. This effect is not frequency or...

What is a typical value for this? I have just got some NOS Russian 6AU6 tubes and they test fine for gm on my AVO twin panel tester. Heater/cathode insulation reads 2 Megohms in every case. Is this satisfactory? Ian

I have just been informed that Ken Kessler has been saying some very nice things about my Dynaco Mk III monoblocs somewhere in the trade press recently. Does anyone have the article and, if they do, would it be possible to get a scan or a digital photo of it? Long shot, I know, but it would be interesting to see it - maybe he's not quite the wattock I've got him down for? :-) (The amps are...

In some preamp designs I have seen the screen grid of a pentode decoupled directly to ground *and in others to the cathode (which is itself decoupled). Is there any particular reason/advantage in doing it one way or the other? Cheers Ian

Picked up from a reply by Sander to Worthless Wieckless: Peter Wieck said: the actual cause of Patrick's concern (as I read it) and mine. Which are pestiferous questions of an open-ended nature delivered by (an) individual(s) who either know better or will never know better by established habits. "pestiferous"

Does anybody know Shaftesbury amplifiers, particularly the Shaftesbury 66? usually used for practise in the home for guitar. Its an old vintage amplifier with 4 valves/tubes. I need to know the valve types or if anyone had a diagram/schematic

If you are keen on electrostatics, please take a look at: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130122106176&ssPageName=ADME:L:LCA:UK:11 where I am auctioning a fine pair of Quad ESL 989s (Vintage Design). This is a great chance to own what has been described as "the best loudspeaker I have ever heard". Thank you,

I notice RDH has several examples of using a 6AU6 in preamplifiers. These seem readily available for reasonable prices (unlike the EF86 which seems to be getting more expansive every day). Has anyone any experience using the 6AU6 in preamps and is it any good? Cheers Ian

I'm looking for a replacement CD/DVD drive for my desktop PC (so standard height, 5.xxinch) I'd like to be able to write Dual Layer DVD's, CD-R and CD-RW and also to play audio CD's. You'd think that any drive would play audio CD's, but I've seen reviews of the Sony AWG170A that complain that it won't play audio CDs! My Plextor PX-708A is starting to fail reading audio CD's, and from new it...

I'm trying to run an optical signal from my PC (source) to 2 units: A Cambridge Audio receiver (for driving my speakers) and an old Sony DAC/ processor (for my Stax headphone rig). What I've done is taken an optical cable from my PC, put an optical (1:2) splitter on the end, then run one cable from the splitter to my Cambridge receiver, the other to my Sony DAC. The Sony receives the signal...

The trouble with being cloned is that you acquire something of a responsibility and/or duty of care and, despite trying to slip quietly out of the back door in all matters thermionic, I am being fetched up to sort out various problems that (were it my own kit) I would sooner run away from, or cure by my customary method of consigning the offending articles to a couple of weeks/months under...

As promised, here is the result of sine wave testing of the ER Audio ESL-IIIB to examine the limits for applied bass signals. The conditions of the test were as follows:- Amplifier, 300W SS, thd 0.005% at 40vrms output, Oscillator, wien bridge, thd 0.05% between 10Hz and 10kHz. ESL speaker set up with 27 ohms plus 5mH in series network
