correct engr dacs, I raised a question nga dun sa thread with regards sa diodes..mukhang schottky nga lang talaga ang puede gamitin.. :D

Eto nga pala yung mga pinagkaabalahan kong build ng Circlo...



1st attempt of the CFP...FAILED! ;D :D



2nd attempt of the CFP...also FAILED!  ;D ;D



3rd and final attempt, the standard & official circlo (ayon kay sir Elvee)...looks stable awaiting clarifications parin.. ;D :D

Ang kulet ko ahehe..ayan natuto kase ako kay sis Johannah "be persevering"... :D

Eto pala ung 1st attempt.... ;D



hmmm..strange bakit kaya nawawala yung image kapag pinost na ??? Anyway....


Engr Dacz,

Pano ba isakatuparan itong turo ni Sir Elvee.. :D

"To measure the quiescent current, you have to connect a millivoltmeter across the 1R resistor, then Iq(mA)=VR(mV)"

Hilo talaga ako dito sa measurements ng Circlo (kakaibang topology) parang nababalewala yung mga basics na natutunan ko, o perhaps mali at kulang ang mga natutunan ko..ahehe  ;D

Pa-coach uli mga sir.. :D

For reference ito yung pagsukat na ginawa ko...sa anong range ba dapat ang DMM? Thanks uli!

Iq(mA)=VR(mV)/1 if measured accross the 1 ohm resistor, or Iq(mA)=VR(mV)/0.47 if measured across the 0.47ohm resistor, this is the quiscient current of your output stage, they should be the same...

nabuhay na circlo ko... ;D and OMG this baby will give the Leach and P3A a race to sonic bliss..
kaya pala marami ring nahumaling dito dun sa DIYAudio. Mas mainit pa siya kesa sa P3A...I mean heat dissipation ng power trannies VAS at drivers...po  ;D  Kelangan talaga lagyan ng mga heatsink pero nung tinetest ko nakadikit na tenga ko sa speakers an tahimik parang ikaw lang sa loob ng asylum.. ;D Ngayon naii-intindihan ko na si JA dun sa paliwanag niya with class A type amps.







size comparison with P3A... ;D you see mahilig ako sa mga compact build.

In case may interesadong mag DIY neto, here are the files... ;)

TO220AC MBR1045 Schottky diode or IN5822 available sa E-Gizmo, BAT85 schottky diode meron sa Watson but those ultra fast type (e.g. MUR120, FR107, UF4004, HER104) at yung mga type na karaniwang nahuhugot sa mga PC PSU, puedeng pang sub sa BAT85. TO-126 VAS marami namang nagkalat neto sa mga surplus TV.. ;D Newport or DEECO marami din. ;)

Build this amp and you will be amazed!

salamat mga sir.. :D

Dacs, generic na piyesa lang naman ginamit ko diyan (see my build pics), maliban lang siguro dun sa 1.5nf
330pf, 220nf 22nf at 10nf, mga box type ang ginamit ko dito. For VAS any NPN type na 4-16pf ang cob at 100-200mhz ft
at  >100v ang Vceo (x2 ng rail voltage) pasok diyan. Unang ginamit ko nga ay yung 2SD669. Ang critical lang ay heatsinking ng drivers at VAS, umiinit ang mga yan mas malamig pa nga ang output. BCs din ang ginamit kong mga TO-92, sa Newport at DEECO marami din niyan.

TY!

Thanks dito sis abeTIR.
Masaya na rin ako sa P3A, pero iba din ang dating nitong circlo. The complexity is challenging. But the signal passes thru fewer stages which for me defined its sonic performance.
Basta sis abeTIR sinasabi mong mas mganda to, gagawin kong main amp sa bahay. Sana near true Class A ang performance. Masaya kasi ang asawa ko sa Class A kaya lang nagbubuga daw ng mainit.

^By far sa lahat ng DIY amps ko the Circlophone was the most impressive when it comes to sonic capabilities.
One thing na na-impress ako dito ay ang baba ng dc offset (less than 4mv lang) at napaka tahimik parang walang
speaker na nakakabit kinailangan ko pang idikit ang tenga ko sa speakers para malamang working ito. The
tricky part ay yung heatsinking maiinit ang drivers at vas neto, but ayon kay Elvee (designer) there's nothing
to worry daw dahil completely servoed ang current ng buong circuit (balanse). Class A attribute daw siya
but rock stable na Class AB ang operation. Try mo search ang Circlotron topology i think this was very popular
before on tube amps. Hybrid naman ang Circlophone.

I have yet to test my other DIY amp, there's SYMEF known to have impressive results sa audio spectrum.
And there's the VSSA with only 8 trannies yet known to match the sonic qualities of an expensive commercial amp.

BTW Tagal nating absent sa thread a' 'welcome back'  ;D

Nagpalit kasi ako ng trabaho kaya nagkaroon ng adjustment pa. ;)
