Hello to anyone reading. I am new to the forum and am attempting to repair my Ibanez AEQ SS preamp. I wanted to run the scenario by some folks who know more than I do about this kind of thing before I start digging in.
Basically long of the short is that I installed the battery in my Ibanez AEL-20 backwards like an idiot because I was distracted and in a hurry, and it took all of 2 minutes for me to realize I had no sound and pull the battery back out. Thats all it took, and later upon removal and inspection, I noticed a "chip" in the center of the circuitboard that was burned. I'm kind of a jack-of-all trades person, so having worked on car stereo amplifiers and home stereos among other things, I figured that would be a good place to start. Doing a little searching on what happens when you put a battery backwards in an acoustic guitar preamp I noticed a post where someone said "transistors make better fuses than fuses" so I searched the numbers on the transistor and was fairly certain that the first character was actually the Texas Instruments logo, and sure enough I have two (in case I ruin one) TLC2264C transistors on the way. I plan on sharing the results, because I see that TONS of people have problems with the AEQ SS and hopefully this might help,but I also wanted to ask if anyone has advice on this project i.e. if I should use a special solder tool to prevent overheating, any special type of solder, best way to remove the old transistor without making a huge mess or scoring the board. Basically if anyone has any pointers to offer I'd appreciate it.
This is just the way I repair things; start cheap and easy, and go up to more expensive/difficult routes, so if I ruin the preamp I'm just planning to learn how to build a simple signal booster on my own, as my Promag Plus provides WAY better sound than the AEQ ever could have ever asked for as a Christmas wish. I plan on using the Fishman however I can as a pickup to put sound to effects/distortion and play with two outputs so I can have acoustic AND electric sound simultaneously, again, just cuz I'm a man and this is what we do: silly unecessary things for no other reason than "because I can". Thanks!
