QUESTION: When changing power tubes in an amp, kailan dapat at hindi dapat mag-bias?

FOLLOWUP QUESTION: Kung hindi marunong mag-bias, dapat ba aralin o ipagawa nalang kay mang raul?

QUESTION: When changing power tubes in an amp, kailan dapat at hindi dapat mag-bias?

FOLLOWUP QUESTION: Kung hindi marunong mag-bias, dapat ba aralin o ipagawa nalang kay mang raul?

May mga amps na hindi na kailangan i-adjust ang bias ng power section... meron ding amps na kailangan ibias kahit matched pair or quad ang ipapalit..

As for bias, the best pa rin kung aalamin niyo yung technical aspect ng amp para kaya niyo itroubleshoot pag nagloko.. Iba-iba rin ang style ng pagbias eh..

Meron yung ginagamitan ng multimeter, meron din yung hum bias.. alam ko si mang raul, hum bias ang ginagawa sa mga vintage na fender..

i think this for the car enthusiast hehe.

You wanna remove the sanding sealer? Dry sand mo with 60-grit. Saglit lang yan.

In my experience, hindi saglit yan. Hahaha! Some guitars have 1-1.5mm thick sealers! X-(

Guys, question. Do you know any DIY sanding block na curved? Para sa side sana ng body ng guitar ala strat. Baka magmukang RG yung body if I used a flat sanding block.

Uh.. gonna use it for wet sanding. Kaya I'm asking for a DIY curved sanding block/alternative.

Are you talking about sanding the sides sa contour and cutaway area? Medyo na-lost ako sa original question.

Normally I use a bottle or a spray can, if that's what you mean.

Depende siguro sa huling nag apply.

Yes. Basta yung mga contours.

Thanks, I guess kailangan ko rin matutunan ito sooner or later (even though I don't know anything about electronics).

Anyway, I've already downloaded Electric Guitar Amp Handbook by John Darr *hingang malalim*.

Anyone who wants a copy of the PDF version, just let me know.

In. Sarap magbasa.

So I tried putting a 12ax7 to my Phase Inverter slot to get more gain / earlier breakup (one of the more popular mods on fender amps). The sound came out horrible when I cranked the amp above 7, it was harsh and shrilly. So i put back the stock 12at7 and the amp pretty much went back to its stock sound.

Now, when I pulled out the 12ax7, it had a small burnt spot but i can't remember if it had this before i put it there or if i inflicted this..Can anybody tell me if i busted this tube? Or it was busted to begin with? Or is this a normal thing?

SPDT for most amp channel selectors. What amp?

[dennis22opina]

Stagg 60 sir chino..

[r_chino18]

Stagg 60 sir chino..

I see.. Yup, SPDT.. You can wire it with a LED indicator (w/ 9V battery clip inside or DC jack if the amp cannot provide enough voltage to power the LED)..

Thanks sir Chino..

[dharzfreeman]

Ask lang po mga sir 
San pwede mag pa set-up ng pick up? Saka magkano ang fee?

[voodoo]

by default these 2 tubes are interchangable. the burn marks might be a big contributor to the "harsh and shrill" sound you got so with that being said you might have gotten a bad tube to begin with.. although im also not disregarding other factors that could cause such burn marks since i do not know the exact type of amp your using...

Ah dito pala. Nai-post ko sa DIY circuits kemerlu.

Pickup build. I think









I used 40 AWG magnetic wire, so the DC is just at 2.59 ohms. Used some Neodymium magnets to charge the poles. Winding the neck pickup as we speak.

I didn't count how many winds I made because the goal was to learn how to properly assemble a pickup.

Now if only I had a tele...

ano po ba ang magandang pang sapin sa solder part ng PCB?

[albumin]

Papi, tanong lang. I dunno kung tama yung ginawa ko na pagsosolder lalo na dun sa may pickup selector. I tried to follow the 50s style wiring. Pero feel ko may mali sa ginawa ko eh. Di ko kasi matest yung gawa ko kasi wala akong amp ngayon. Nasa ibang bahay ako at naiwan yung amp ko sa bahay talaga namin..

here's the pic.

Any plastic material or foam, and make sure it you cover the entire pcb layout.

[mbsunga]

ano po ba ang magandang pang sapin sa solder part ng PCB?

So far ang nakikita ko is plastic or paper

Ask lang mga sir.. may gumawa na ba dito ng transparent na pedal board / flight case using poly carbonate, pvc sheet, and equivalent?

Id prefer D.I.Y. flight case para lang mag kasya ang 15 pedals and wah...
Im thinking na transparent na rin 

[thuzkee02]

I've just recently bought a Washburn Mercury Series na guitar... for a low price kasi sira na ung wirings nya . But all the Pick-Ups are stock Washburns... H-S-S configuration. 5-way switch. Try ko siya i-restore... hihihi... Excited dahil may project guitar na ako...

Tulungan po niyo ako, ha? 

[Jnsk]

Mga ser, mas okay ba gumawa ng diy flight case ng pedal board kesa bumili? I have zero experience in building stuff like those, pero mas okay kaya yung pag aralan ko na lang kung pano? A few months ago bumili ako ng flight case doon sa classifieds.. After ilang weeks may natatanggal na na screw tapos yung part sa hinge parang nasira.

Yan din experience ko bro..

Kaya ko binenta yun surelock ko dati, dahil di magkakasya mga boss pedals ko magdadagdag pa ako ng zoom. Yun pinaka-malaki sa bilihan which will cost 4K+ minimum di rin magkakasya mga pedals kaya naiisip ko mag D.I.Y. para makatipid... nag canvass ako ng poly carbonate




para transparent na.. makikita na kung may nawawala sa board after ng gig 
It cost 1.8k wala pa yun mga hinges, angle bar for sidings. mag canvass na rin ako mamaya sa work shop kung magkano mag pa rivet
