the plot is a one for one comparison with the FE206E in their respective alignments, but in the same environment. The red plot is the fostex. Ed, are these using the F2 amplifier? They look a bit similar to mine when driven with a high source impedance. I don't yet know how to smooth that sort of t...

don't suppose anyone got a photo of those with the grill off? Hi Richard, not at the meet, but here are some: http://www.communityenergysaving.co.uk/Stuff/P6210001.jpg http://www.communityenergysaving.co.uk/Stuff/P6210004.jpg http://www.communityenergysaving.co.uk/Stuff/P6210008.jpg The thread for ...

Pass F2 brought out of retirement for the day..... Vofo with new experimental alignment for new FR driver Pity I missed Sunday, wouldn't have minded hearing that. Brian's one watt solid stater was amazing for the amount of power it had. Thanks for the kind words. I'm quite happy with it for now; I ...

Is that a solid state amplifier with coaxial speakers there Ed?

Sensible combination if it is

Thanks to Steve for organising the weekend, had a really good time and made very welcome despite not having anything that glowed - maybe next time...

Brian AKA Chris's dad.

Hi Ali, since Chris will have forgotten...

We will be there on Saturday all day - hope to see you then.
Thanks,
Brian.

That may be closer than you think... http://news.yahoo.com/s/ap/eu_switzerland_antimatter Hmm, 15 minutes is a start, but would I need an antimatter octal base for it as well? Then I suppose, antimatter cable, solder, components, interconnects, speakers, air to vibrate and ears too :D there is a lo...

So true. Speaking of wasting a bit of energy, has anyone any experience of valve/mosfet hybrids? http://www.enjoythemusic.com/diy/1108/borbely.htm http://wiki.faust3d.com/wiki/index.php?title=DIY_MOSFET_Amplifiers_Overview http://blog.xuite.net/alex.fatc/AudioDiy/3432229 I could convert my existing ...

According to this: http://www.sengpielaudio.com/calculator-efficiency.htm that's 4% efficiency, or 96% waste, and there I was worried about my class A amplifier.

A word of warning, guys - if you see Dad (or Brian to you guys, unless there's something he's not told us...) connecting a one of http://cgi.ebay.co.uk/SAMSON-SERVO-240-PRO-QUALITY-STUDIO-AMPLIFIER-120w-x2-/300565177213?pt=LH_DefaultDomain_0&hash=item45fb14a37d <<those up to his speakers, it mi...

Get the scope out. Looks like I won't be working in the garden tonight as it is pouring down, so I could even assist if you ask nicely

I don't get calls for competing mobile networks any more. I told them I was interested in switching, and answered truthfully when asked how much I spent per month with "sometimes as high as 3 or 4 pounds"

capacitively coupled hum and crap from the other transformer windings are radiated all over the insides of your box by the heater wiring. Bearing in mind that at least one other winding is likely to be high Voltage, so you get high Voltage hum and crap capacitively coupled to the heater winding. Go...

Hi Philip, try this: http://www.dutycalculator.com/

Every isolated (floating) thing I have, like television, DVD player, laptop etc., sits at around 120VAC i.e. half mains. It is via a high impedance, so it's quite safe. I guess that the heaters will do the same. The heater transformer will leak slightly from the primary to the secondary, and the sec...

Maybe it's the player that makes the difference. My only audio source is an iPod, and I use it to play everything from lossless to 128kbps MP3 and podcasts. My iTunes downloads sound fine - but no better - [really picky mode on] the focus is not as good as it could be, so people sound like they have...
