If you replace the power IC you may need to add some fresh thermal compound between it and the heat sink it is attached too. If you have the power supplies and a preamp signal that just leaves the power IC they have them at Mouser You could also consider the TDA2040 also it puts out higher wattage with the same power supply rails so it must be able to get closer to the supply rails at maximum power out. Also could see if you have a preamp output signal if there is one on the amp. You could measure the power supplies in the amp first you should have +/-15 and +/-9 volts. Even though the IC is short circuit protected you may have blown it.

something: nada, it does'nt even smell burnt.Ĭhecked a small fuse on the inside: seems fine.ĭidn’t you start the Crate V5 mod thread a long time ago? I found a schematic here The one linked there is hard to read but searching on the web found threads that stated the output amp IC is a TDA2030. Second step, i checked the speaker with a different amp (and an instrument cable, for now), and the speaker is fine.Ĭhecked my amp's head phone line. So, once the cursing stopped, i checked the speaker cable and found out what MY mistake was: one of the 1/4 plugs did'nt have the inner plastic sleeve so the solder joints touched the wall and. This happened immediatly after i strummed my guitar, no chance to turn the amp off before the silence (3-5 seconds). so i went to my local radio shack-type store, bought the necessary parts and did all the soldering and ended up with a new speaker cable for my Vox and my Blackheart cab. I read lots of threads on the subject and finally understood WHY. rookie mistake: just yesterday i found out that using an instrument cable for a speaker cab ain't a good idea. Here's what happened with my beloved Vox 15R. sorry (i know you did'nt miss me anyway).
It's been nearly a year since i last posted something here.
