20 Most Recent Tascam Ga30cd Guitar Amplifier with CD Trainer Questions & Answers

A common problem is that the switch contacts on the headphone jack that send the audio to the speaker when headphones are unplugged go bad. Some of these are so low quality that after a few times of inserting a plug the contacts no longer make. If you can access the jack, you might find a jack similar to: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=RA49B12B-ND
What happens is the spring tension on the tabs over the top of this that contact the leads to the speaker lose tension and no longer press hard enough on the contacts to make contact. Try to open your unit and see if it has this kind of jack... Frankly, these jacks are JUNK and a chronic problem.

I suspect there is bad soldering on the circuit board in the vicinity of that button. The movement causes the connection to re-establish. It isn't necessarily one of the button leads. Look for a little grey line around the menicus of one of the soldered leads.

What is the part... there are many and depending on the parrt number there are different places.

If it is the amplifier power chip you are after, then it may be in the TDA series such as the TDA2050. Those are available either through Digikey.com or Mouser.com.
There are other op amps in these for the preamp section...If you had included the part number I could have found a vendor for you.

Only if you are using microphones that require phantom power- otherwise no.

Several of my music programs seem to have a limit of around 2Gb for a track... this is inspite of having plenty of disk space... this seems to be a limit set by the program rather than the resources available.

I recommend contacting Tascam at this link:http://tascam.com/contact/support/ Describe your problem. As far as I can tell there were some problems with the media you could use. This article might help:http://www.sweetwater.com/forums/showthread.php?10128-Tascam-CD-RW5000 You could also try contacting Sweetwater Sound and ask:http://www.sweetwater.com/sweetcare/ They have a great staff.

Here are some good links for you:http://audacity.sourceforge.net/ ( Audacity is a free recording program ) also:http://www.reaper.fm/ ( Reaper is the software I use and is full featured and worth the licence fee and free to try) also:http://www.recordingreview.com/ ( excellent site to answer all your recording questions. Note the free download.)

If you are trying to copy disks that are copyrighted, the unit is likely locked out with copy protect firmware from doing copies.

I would vote for a power supply issue on this one.

You can use headphones or monitor speakers that are hooked to an amp. If you don't have one ,consider downloading a manual:http://www.tascam.com/i-3582-232-128-1-4A000F90.pdf Pay attention to the caution on page 9 and the hookup diagrams are on pages 12 and 13. Hope this helps.

first set the in and out points of song make sure your holding down the shift key while setting in and out points.then pres shift key holding down on it pres master key it should start flashing.then pres record play.good luck

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.
