I bought a stereo amplifier and a turntable, both old but still functioning. However, I have been encountering some problems.
Before I got the stereo amplifier, I was using my old Sony stereo component with phono input, and there were no problems at first. Then recently I noticed that the sound from the right channel was quite distorted, so I decided to get a new amplifier. It has a knob for stereo or mono. In stereo, there's normal and reverse, while in mono, there's left, right, and left + right. If I place it in stereo, there's no or very weak sound in the right channel. But in mono left + right, there's balanced sound in both channels. However, there's no sound when switched to mono right.
Then I checked the touched the headshell wires of my Hitachi Lo-D HT-462. At first, just touching the headshell produces a humming sound even though the turntable is properly grounded. And when I played a record, there was very little sound coming out from the speakers. I touched the wires again, and there's no more humming sound and the volume is back to normal, but still no sound in the right channel when switched to mono right.
Is this normal? If not, is it a turntable or amplifier problem? Thanks in advance.

try other source as input, example cd player (connect it thru aux in).
if same issue, amp problem.if not, its with your turntable.
amp:many things could happen-damaged channel, dirty switches, pre-amp to main switch dirty, etc
turntable: cartridge coil open, cartridge wire connection, not good, broken wire/rca neck, etc.
hth :)

I will use other sources first, then I'll post what happens.

I tried my DVD player, and it works well on the amplifier. Both channels are working. Funny, but now my turntable also has output in both channels. Must be a minor glitch or there must be something loose in the turntable.

for some amps, that issue comes and goes like our old vintage amp. i can easily see the missing channel on mine because it has a bright digital eq on the front panel. sometimes it'll work and after 2 mins it goes out and then comes back on again. it does not work most of the time. i haven't sent mine in for repair.
-
It's at it again. Nawala na naman yung sa right channel. I really think it's the turntable since gumagana naman pareho pag sa CD player eh. Must be something loose sa cartridge and headshell.
-
Have you checked the cables connecting the turntable to the amplifier. I think it is either the wires or the connection of the cartridge. Check any loose connections. Or try to use another cable which you have tested to be in good condition.
-
experienced it before...
i just resolder yung ung silver wires sa stylus...then nag ok na...
kaso hirap i solder nyan he he
-
Mukha ngang delicate yung wires eh. Hanap siguro ako ng marunong mag-solder. Last time I soldered something was in high school pa. Hehehe.

OK, so I was able to fix the problem of the missing channels by sending the amplifier to Raon for repair earlier. Now, I've got another problem. When I use my Kenwood turntable, the sounds are clean. However, when I use my Hitachi turntable with a new headshell, cartridge, and stylus on the same record, there is distortion. I tried the old headshell, cart, and stylus on the same turntable, and there is no distortion. I attached a different stylus to the new headshell and cart, and the distortion was minimized, but still it's there. Is it a problem with the new parts' compatibility with the turntable, or just an issue of cartridge alignment?

might be the alignment or vtf.
you can align it yourself, just browse for turntable protractor and print the one suggested for your brand ;D ;D ;D

I already tried that. Being a newbie, I'm afraid I might be doing the wrong thing. I better leave it to the experts. But as long as those are the problems and can be easily remedied, I can rest well. Heheh.

dont worry bro, nobody is perfect ;D ;D ;D
but it is still important to learn it... just follow the given instructions... and its fun ;)
just get the measurement of your TT's pivot to the spindle then you can easily use
any of the arc protractor that correspond to your measurement. ganun lang... ;D
sa anti-skate basta may bala ka lang LaserDisc ayos na!

you need a phono stage.

hi dvdmates,
Somebody gave me old orig vinyl albums, and decided I wanted to hear them, so I bought recently an old turntable pioneer, (condition is with power at 220v/turning/arm working/without the needle) and just sourced it myself, however to my dismay, after installing the needle and setting the vinyl, no sounds can be heard in the speaker. I could hear the a little sound just above the turntable and the needle only.
I tried hooking it up in this condition
1. yamaha avr amplifier at aux/cd/dvd source (no phono)
2. tube amp at cd/aux/dvd (no phono)
Is the turntable can be hook only at phono?
is there a problem with the player?
pls advise Im badly excited in heraing the vinyl, and still got no budget in buying new and 2nd hand branded TT at the moment. Bought the pioneer at P300 hehehehehe
pls advise any technical assistance is highly appreciated
your amp must have a "phono in" otherwise you wont really hear anything.
if none, they you can buy phono pre-amp/stage.
sayang mga plaka mo brader ;D ;D ;D

Parang alam ko kung saan nabili ito. Sa sulit.com.ph, di ba? You need a phono input sa amplifier mo dahil the sound coming from a turntable is not line level. Kailangan mo ng phono preamp para maging line level ang volume nya.

Yes, that's exactly what you need. Magandang klase na yan. Merong mga binebentang mura sa e-bay, pero di ko lang sure ang quality. Naunahan mo ako doon sa sulit eh. I texted the seller one day after mo mabili. Hehehe.

hi dvdmates,
...
Bought the pioneer at P300 hehehehehe

we usually associate the needle with addiction.
the turntable has a needle.
if you start buying more turntables and lps and can't stop yourself from buying even more,
then you're letting the needle win!
just enjoy the music!

Ah, now I get it. Hehehe. Para ngang I'm letting the needle win dahil sa ngayon, tatlo na turntable ko. Yun nga lang isa, walang needle. Hinahanapan ko pa. Tapos, hinahanap ko pa yung lumang turntable namin na National. Sana nakatambak lang at hindi pa naipapamigay ng nanay ko.

Did you try going to Raon to look for the needle? Meron sa Armstrong na Pioneer needle ah.
-
meron na sir nakuha ko na by order po sa pioneer repair center sa may DIAN st makati, thanks pag nasira ulit duon nako bibili,,,

problema ay phono stage para sa AVR and tube ko (cd/dvd/aux), swerte pa din may nagbigay opismate ko galing tatay nia 1973 zenith mc6020 tuner/amplifier/8track player check ko likod may phonostage,,,,yung speaker conncetor po ay rcs type pa yun lang ang hindrance at the moment, kasi puro banana plug yun mga speaker connector ko, pano ko gawin dulo terminator ay banana plig tapos sa zenith speaker ay RCA connector....????hmmm ???
Puwede sigurong ipabago yung interconnects sa electrician.
-
OK, so I was able to fix the problem of the missing channels by sending the amplifier to Raon for repair earlier. Now, I've got another problem.
bro, i have a few questions. how much did it cost to get it fixed? anung component yung pinalitan? thorough cleaning ba and replacing of caps? anu yung prob daw?
cuz i'm planning to have my amp repaired din. and it's good that i have an idea para iwas taga ng technician. thanks thanks!

Yung sa akin, dahil sa kalumaan, they had to clean the board and resolder some parts. Wala namang pinalitang mga piyesa. Nag-angatan lang yata yung mga connections due to age. They charged me P700 with 2 months warranty. Dapat nga yun, P800, pero natawaran ko.
However, binalik ko rin sya after a day dahil nagsimula na namang humina yung sound sa isang channel. Nung tinignan nila, wala namang problema. The weird thing is, I think it's the interconnects of my turntable that's causing the problem. Pag kasi nawawala yung sound sa isang channel, I spray the turntable RCA terminals with contact cleaner, and bumabalik na yung tunog.
A change of ICs might be in order to fully enjoy my records. Akala ko, nakamura na ako sa P2,000 na Lo-D turntable. Hehehe.
-
nong binigay may power, kaso wala out na signal, dinala ko sa kinetic sa robinson pioneer, gumagawa duon ng amp,(maker ng AMX tube amp) may sira nga mga caps/resistor, inaudition ko pagtapos ganda tumunog solid state,can drive their 350 DIY na speaker nila,,, kaso dipa nila mapagana yung vu left n right meter at saka yung tuner indicator needlle level, kaya iniwan ko ulit duon, ang running nia P800 parts worth plus 1700 labor, bale 2.5k na, budget ko to have it repaired gang 4k, sunod nila icheck yung 8track kasi nung binigay sa akin dami orig na bala, galing pa sa us,,,pag tumaas na bill nuon pahold ko repair ng 8track, ipalit ko lang yung turntable. na P300 ::) hihihihi may phono stage yun zenith
ayaw ko dalhin sa mga labas lang na repair shop kasi sariwa yung unit, padalaan kita ng pix nxt
I haven't heard an 8-track tape being played yet. I jumped from vinyl records to casette tapes kasi. Heheh. I think it's better kung yung turntable muna unahin mo.

@edgarryan
thanks for the info bro. tama kayo, hirap magtipid, minsan sakit sa ulo ang kapalit. ::)

But the satisfaction naman pag gumana nang maayos yung gears mo, di mapapantayan yung ginastos mo.
-
Audiophile and DIY'ng are related to each other. The good thing is the Satisfaction once you configure it correctly ;D It's not only the quest for Best sound but a struggle to achieved your Goal and the best thing on it is the LEARNING!

mm and mc are the common types of cartridges. the cer probably stands for ceramic, which isn't that common today. the cartridge to use would depend on what type of phonostage your amp has. from your description of your amp, your choices are limited to moving magnet [mm] cartridges.
you say that no sound came out when you connected your tt to the phono input of your amp? if you are sure that you selected the correct input in your amp, check the connections, including those on the cartridge. there might be something loose.
-
Kung puro humm ang naririnig mo, check the grounding. Baka rin corroded yung RCA jacks ng turntable. Was the amplifier checked for defects? Saka baka mali ang pagkakalagay mo ng needle.
Yung MM (moving magnet) and MC (moving coil) are types of cartridges. Kung MM ang cartridge mo, it should work sa Zenith mo since may option sya for that. Besides, mas malamang na MM yang Pioneer. Ano ulit yung model ng TT mo?
-
sir edgar ryan thank you very much, sige check ko yung model ng pioneer, gusto ko sana pix para makita nyo at mapadali ang troubleshooting, pix ko back ng zenith at pioneer connections, pls advise how to attach pix po dito
appreciate very much your inputs
You will have to upload it to imageshack or something para mai-post dito. E-mail the pictures to me na lang, then I will post it for you. [email protected]
-
yung nabili ko po na karayom, do i need to establish it too if MM or MC sha?
I don't think so. Chances are, MM yan. Pag MC kasi, kasama na sa cartridge yung stylus (I think). And at that price, MM yan. Mahal ang MC eh.
-
sir ryan,
appreciate your help on this, tonite ill take pix of it (iphone lang gamit ko) pag naka on- and also the back, by the way matalas sa high ang amp na to at 8ohms im using 2 rtia7 na polk, sana mapatugtog ko na yung mga old vinylys at yung kinuha ko k superman na vinyls....
Kung talagang di mo mapatugtog, ibenta mo na lang. Hahahah!
-
thanks sir the question is ano pa kulang para gumana po ito? itry ko kaya sa iba amp na may phono stage(ng kapitbahay kung sakali) yung TT, baka yung phono MMAG NG ZENITH ang may problema...? isolation procedure muna???
Yup, isolate the problem muna.
-
Ey, any update on your turntable repair?
-
Kung walang ground wire yung TT, most probably integrated na sa left RCA cord yung grounding nya. Meaning, you don't have a problem with ground anymore. Plug mo na lang sa amp mo, then play. Pag may humming, either naputol yung ground wire nya kaya wala kang makitang wire, or try to move the RCA plugs. Pag nawala, good. If not, pa-solder ka ng ground wire.
-
tinry ko na, dipa din tunog palagay ko may problema talga tt... :-(
-
Patignan mo kay halls yung turntable, o kaya ibigay mo na lang sa akin. Hahahah!
-
Hehehe, asahan ko yan.
