Re: ariels

You'll find my name from time to time on there, years ago. As Stephen says, hard to find anything now. it became a compendium of anything related to the potential drivers, horns, acoustics, stereo etc etc and a lot of tedious argument, much of it stirred-up by Earl Geddes. It's a shame as there was ...

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

I ordered 10 from Mouser. It's mad that such a small thing is so important, but honestly, getting the right caps there is the difference between 'very good' and 'magic' . I keep thinking back to what Jono Noble said years ago, which I tried to argue against : .. "everything matters, enormously". He ...

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

I couldn't hear any difference myself between 330n and 470n , if it's any help.
I should order some of the ones that are supposed to come 3/2020, at least I have enough to use for current projects.

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

HMm, the world seems to have run out of large value C0G capacitors. I wonder how a film would do. I know in testing, that cap mattered, but I don't remember if film was tried. We tried a few, and they all seemed to have too much inductance. I seem to remember the first cap that sounded properly ope...

Re: Forget Cube speaker Drivers .........is this the future?

I'd have to check other drivers to see how low distortion is - speakers are typically a long way from being like amps. It looked interesting until i saw it's only 84.9dB/w efficient. there's always a catch. But good to see the high Qm. Cube, see HiFi collective for example, the 'Magus' 8" unit looks...

Re: Phono Hum

Not bad. Nick uses them in the Reference.
Soft mounting might help a bit - Nick has them in an enclosed box, unlike me.
I have some B&Q tube dampers - didn't put them back on yet, will check. But at present it's just residual hum that's the only audible thing.

Re: Phono Hum

I wouldn't recommend what I did, that's for sure ! It was a desperation measure for hum which at that time turned out to be a broken earth wire down the centre of the circuit. Maglev sounds very novel indeed :shock: My next phono intends to have some of the valves soft-mounted using 'well-nuts' ( M3...

Re: Remember These?

There's not much that can beat a good old-school carbon pot for volume control. I am very grateful for Steve S for providing me with one for the tweeter amp.

Re: Phono Hum

Just got the phono back in playing and it's MUCH better. I can only hear some hum quite close to the bass units now. Bass and lower mids have improved, of course ! What a relief after putting up with it for so long. Just playing 'Don Juan's reckless daughter', as you'd expect. I also took the opport...
