Dear Sirs,

I would like very much to hear some opinion from people who have experience about powering the clock generator circuit with batteries.
I strongly think this could be a way to get wonderful clock stability and, in conclusion, exceptional sound.

Thank you very much indeed.
Kind regards,

hi beppe61, I tried it with my clock, and I was not impressed.
Batteries can be noisy too.

Dear Sirs,


thank you very much for your extremely kind and valuable replies.
I can only say that your comments have changed completely my belief.:dead:
I truly thought that batteries were "the cure" for most of digital problems.😱
And for the first time I see the word "noise" related to batteries.😱
I am sincerely upset.:xeye:

Thank you very much anyway.😀
Kind regards,

beppe

Hi Beppe,
Batteries are a "cure" for other problems in vibrators.....

Guido, good post. Nice to see someone went to the trouble of actually measuring battery noise. This has been a dirty little secrect for too long. Batteries are not perfect voltage sources.

They are chemical reactions. I like to think of boiling water as an analogy to the molecular conversions taking place. It's no panacea. On the other hand, it can easily solve ac related hum issues in some equipment.

Hi Jim, your post amply demonstrates you are not a chemist. Boiling water is a physical process; a battery giving off current is a chemical process (electro-chemical). The latter is not constant but fluctuating like the flames in your cosy fireplace to give a better analogy.

Dear Mr. Tent,

thank you very much indeed for your extremely kind and valuable advice.
Exceptionally interesting tests indeed.
And also a revenge of instrumental assessments on listening tests.
I mean, in the end an oscilloscope is always the most reliable and sensitive tool, much more than a human ear I am afraid.
Thank you very much indeed.

Kind regards,

Battery Powered Clock

I have had fantastic results powering an Audiocom SC3 in my Sony SCD-1 with batteries, as well as all other circuits in the CDP. A well-designed battery implementation beat the best I could design with AC/DC discrete regulation stages by a significant margin. The keys are low impedance batteries (e.g. 2 milliohm Optima Yellow Top spiral cell or Enersys Odyssey PC2150 thin-plate), decoupling the battery from the application with a parallel array of fast filtering caps located inside the CDP(e.g. Rubycon ZA), DC trunks of quality wire, short length, and adequate gauge (3' or so max length and 20-25 strands of 24 AWG poly-coated magnet wire to minimize skin effect), and where possible, running the application unregulated directly off the battery. The results are astonishing.
