Question about Amplifiers & Preamps

1 Answer

Preamp Hi! I'm not very technically minded as far as insides of stuff goes. I took off the casing and all I can see is soldered to the circuit board. What do you mean by 'tubes'. I cannot see anything i would be able to remove. Thanks!

SU-G91 amp over load wont reset.


Technics SuG91 uses a couple of SVI ( I think they are SVI ) packs for driving the speakers. These are big black plastic things mounted to the silver finned heat sinks. 95 % of the time, this is the problem. They are not very tolerant to any type of abuse, and all the amp has to do is overheat once and they are toast. 1 The SVI packs are expensive and that amp may not be worth fixing. If you know how to de-solder something, and are comfortable working with voltages that can kill you, you can unplug the amp, make sure it has been unplugged for at least 20 minutes, and gain access to the area of the circuit board that the SVI packs are soldered to. De-solder one of the packs and remove it from the unit. Make sure that when you de-soldered the SVI pack that you DID NOT accidentally solder one solder hole to another ( create a connection from one hole to another that shouldnt be there ) . Re-assemble the unit correctly, plug it in and turn it on. If the display lights up, you have removed the offending unit and need another one. If it is still in protection, then mark the one you took out as "possibly good", and repeat the removal procedure for the other SVI pack. NOTE if you decide to replace the SVI pack yourself, you will need heat sink compound ( that goo that stuck the original pack to the heat sink ). you will need to remove the old stuff ( a rag and some alcohol will work ) before you apply new heat sink compound. If you are uncomfortable with ANY OF THAT, then take it to a shop that offers free estimates. Good luck and BE CAREFUL....Rob

Svi 3204


From your question, I don't know if you're looking for an amp board, or preamp board. These two functions may be covered by multiple boards.In any case, they are no longer available. Your unit would need to be troubleshot by a competent audio tech to the component level. If you need more assistance, or would like to inquire about a repair, please visit my website, audioserviceclinic.com. Thank you.

Su-c800u pre-amp switching not steady, keep darting from one mode to another and disrupting smooth flow of music


I had the same issue.the contacts on selector switch is dirty.All u need to get a good contact cleaner and spray the selector rod( remove knob first with preamp facing up), the liguid will find leak into selector and clean contacts.
after doing mine, the slector knob feels more solid when turned and does not change input anymore.

Cambridge A5 Amp, only one speaker works when phono selected


If both speakers work okay on other inputs .Then cable from pre-amp to amp and main amp are okay. If phone RCA jacks go directly to electronics board .Then its possible solder on phono jacks need to be resoldered or other connections in that section.If unit needs repair you can also purchase a phono preamp from radioshack hook up your and use it on other good inputs such as CD etc..Please note PHONO inputs are only for turntables .If a non turntable input such as CD,TAPE,TV Etc is used on PHONE .Then you will overdrive this input .

Phonic k-12 powered mixer Nothing happens when I press the power


Hi...

Most new stuff has the fuse/fuses mounted in clips on the power supply board.
If yours is anything like the one a picked up for one of my bands, you can take the bottom plate off and see everything inside.
Look for where the AC cord goes after the power switch.
There should be a circuit board with a fuse or 2 mounted on it

Amplifier goes open after operating for 15 - 20 minutes, no sound


HI...
It's probably a solder joint that's intermittant. I see a lot of these in my work.
Have a tech with good eyesight give the main circuit boards a once-over for solder joints that dont look right.

TECHNICS SUPER BASS, DOUBLE BASS AND TRIPLE AMPLIFIER


Have you checked all circuit boards for good solder connections.
Also if the boards had been wet from anything, you might clean the boards and resolder all connections specially in the power supply and audio section.

Let me know.

Carver C11 preamp problem


I found out through the Carver Audio forums that metal shavings inside the case are an issue with this unit. So I used an achohol based spray and cleaned the switchs and the circuit board, (there was a fair amount of shavings found). It has been running for 14 hours with no problems.

Gain on one channel stuck at max


Hi there

Check for a dry solder joint on one end of the vol control(earthy end). This will be causing your problem. The pot itself may actually be faulty to. You can always get stuff like that, just got to identify it. Check soldering to the pot first.

best regards
