SUNDAY CLONE TRIPPING....







still waiting for my pots and some mojo parts..... hope to finish this tomorrow mornin..... happy DIYing....

[paparoni]

musta kelan ang toneparty?

share ko lang my very first, three ordered pedals ever:

lovepedal ETERNITY BURST edition + mod clone








fulltone 70's FUZZ clone









I know.... I dont have a good soldering technique... hehehehe... but it seems everything works fine.... hahahaha....     happy BLACKOUT DAY

[siore]

I like how your soldering looks bro.    Tanong lang, how come you don't have shielding this time around?  In some of your plastic enclosures, I thought I saw some shielding paint?

@SIORE

SALAMAT PO..... hahahaha sa totoo mas maganda yung solder nung iba dito.... and may paste pa sila talaga not like me derecho hinang.... hahahahaha.....

i haven't thought of that these past few days.... pero kasi nung mga nakaraang jammings ko.... i havent heard any much of noise..... since everything i have as of now is puro ODs... not really high gain distortions.... usually cascaded pa sa TS ko... so everything is clean and smooth.... but my TS has an ALUMINUM TAPE SHIELDING..... in this way i prevent RF from entering my primary booster....

Tried my hand at reverse-etching. 



BTW, astig yung DIY layout creator!  Anyone can use it. 

[Musikerochan]

DIYLC? i use it! pretty straight-forward, nga lang walang router function kagaya sa Eagle, kaya very manual yung placement ng parts.

yung Fetzer valve men sundutan mo kaya ng Ge clippers? booster na, overdrive pa.

tyaga mo mag-etch men!

ginagamit mo ung router function? paano?

Oo nga matagal!    It's worth it, kung gusto mong malalim yung etch nya.  Hmmm pwde ko lagyan ng clippers, pero may TS na ko for overdrive and gain boost eh.  Ok na rin 'to, tamang clean boost, pero tingin ko kelangan pa ng filtering sa power supply, maingay kung sa harap sya ng cleanish to dirty amp.  Next time na lang. 

[Musikerochan]

yung signal symbol, yun na lang ginagamit ko. pagkatapos kong mag-autoroute iririp-up ko ulit lahat ng traces. the autoroute function i use it para lang makita ko kung san iikot yung traces. then manual routing na.

hehe, JFETs e a 100ohm in series sa supply siguro would fix that, or a 3.3K resistor sa input before the 1Meg resistor.

pwede palang 3.3k kala ko hanggang 1k lang.. di ba magbabago ung tunog kung 3k3 gagamitin?

[brune]

san nakakabili ng vero board? ayoko nung sa deeco e.

[jmorrero]

musta kelan ang toneparty?

pogi bro

yun oh... ayos looks bro

[kawayan_strat]

Tagal na di nakapag-post!

Line selector at drive pedal lang po.

sounds and looks promising. \m/

hindi naman, in my experience at least. pag high gain at matindi yung oscillation i even use 10K, gaya sa thor. then add a 100pF cap after the input resistor, before the input cap.

malaki pa rin ang epekto ng pick up shempre sa noise level.

ano ginagawa nung capacitor to the ground?

filter ung high frequency?

ako nilalagay ko sa bypass mode.. kaw san? dun sa mismong circuit?

basically it chops off some of those RF that interfere with the signal and gets amplified. sa bypass nakalagay yung cap? awts, it will add to capacitance and will dull your bypass signal. wire it so na nakaseries sa input nung circuit yung resistor and cap, at hindi sa bypass mode.

yeah will work on it later...

dapat pala pag gumawa ka ng pcb meron allotted na pads for those two para incase of RFI malalagay mo walang hassle.

ganun nga men. especially sa mga JFet circuits. lalo na sa mga high gain distorters. dapat pati power filtering maganda din. daming dagdag na components pero worth it naman, kesa magtiis sa noise. at least sa ganung paraan attenuated na kahit papano.

100 ohm nakalagay sa power section.. 9v to bias.. pwede pa bang taasan yun?

[paparoni]

@turi & sir jim:
ui thanks for noticing my work 

@musikerochan & quaternottriplet:
what you are talking about i think is the 60Hz hum which is common on most of amplifier circuits,
ang alam kong ginagawa is to put a 100uf cap from the supply to the ground.

pero effective ba maglagay ng resistor is series w/ the power supply?

[Musikerochan]

@quat,

pag mataas na masyado, voltage will sag. not a bad thing depende sa sitwasyon. i'd say you're fine with a 100ohm resistor na sa supply.

@paparon,

yep daddy! antimano meron nang power filter (100uF electro cap = 100nF ceramic) and protection diode dapat. i was advised before to add a 100R before the power supply to help rid the noise.

parang ganito:

+9V supply > 100R > power filter/diode > crkt. power filtering AFTER the 100R resistor daw. teka hanap nga ako ng schem.

[quaternotetriplet]

yan dapat may scheme na..


ung Lovepedal eternity 390r ung gamit.


@roni

edi magkaka 3 capacitor ka na sa power section?
