In Reply to: RE: BATTERY POWERED FM TUNER? posted by ziggy on July 24, 2009 at 00:00:45
my tuner is an old simulcast rcvr, rebuilt and upgraded, but with the power amps OFF!
And my amplification chain has 3 very large PSU's.
I am a convinced BIGGGGG PSU guy these days.
Earthing matters, too.

I definitely agree with the whole big idea, as in big transformer with big tank caps (and some little ones too) but would add that low noise and low impedance regulation certainly will bring alot to the table as far as good supplies go. Its really hard to beat an appropriately spec'd lead acid battery bank but a top notch designer can probably beat the low impedance part and come very very close on the noise.
G'day Timbo........yeah, I agree, there is no such thing as ''overkill'' when it comes to power supplies - AC or BATTERY......I've heard the difference!
On the net, ALTMANN AMPLIFIERS (B.Y.O.B : ''bring your own battery'')has an interesting say on running his mini class d amp on battery. He mentions that a fully charged battery has ''explosive dynamics''compared to one that has it's amp rating down.
http://www.mother.of.tone.com enjoy!
After a few bad runs with trying to get amplifiers on batteries and having then go weird or blow up on me, I have decidec to go back to my SCOTT LT110 valve tuner.
I know for certain that it sounds fantastic...........don't know why I bothered going down the solid state route?!
I once had an octave eqauliser, and then two 1/3rd boxes, and a Phase Linear Autocorrelator, and an SAE 5000 declicker.
I eventually got rid of them, all.

HEY!!!!........that's all good stuff man!............and you got rid of it?????!!!!!
Why ELSE?Positioning spkrs properly and listening pretty much in the near field is a lot cheaper, and does less damage, than processing does. Don't forget my main reason for audio as a hobby is classical European music which was until the romantic period based around and sustained by church music.
To be satisfying for me the music making in the space has to be coherent, so I can hear the art happening in real time. So, real stereo recordings are central hence my definite views about that.
To me gear matters so that it helps, and for me 'display' is - huh? beyond sheer UGLY, I mean!
And, that is it. If digital were better and I had the money, a truly good AtoD box and DSP BOX just MIGHT get considered.
OR a lot more room treatment.
My gear now? click below.

Love your system..........you ARE ''a serious scrounger'' LOL!
Gotta get back in to vinyl.
Het TIMBO.......I've got a couple of old Philips, ex ABC transcription turntables. One I have the motor, platter removed, and the motor shaft turned for the correct diameter to run 33&1/3 r.p.m.Just got to put it all together.
Do you know this turntable?.....I've seen and come accross a few over the years. They were originally idler wheel drive, but all the ones I've seen were stuffed.
