Hello everyone, I'm new both to this website forum and the interesting world of electronics. to include circuit building and repairs etc.
Just to introduce my self my name is Mike, I work as an information systems. I'm a musician as well which is the reason to come in here and pick every one's brain! I have 3 tube amps one dies on me and one I'm slowly restoring by sending it to amp tech and dropping hundreds of dollars on a techs eagerness to work in high powered amps confidently without worrying about getting shocked or killed. I have read minimal web sites and books on electric circuits and power amplifiers and I have skills with a solder gun, which I know makes me one of the most dangerous persons on earth. But I recently purchased a book today from radio shack "Getting Started in Electronics" and my knowledge of this subject is growing every day. Eventually I would love to buy a DIY Tube amplifier kit and build it with the confidence that I too have built a high powered amplifier in hopes that I dont kill my self by simply plugging a guitar into it. LOL.
Well enough with the introduction i will just get into the "meat and potatoes":
you have to crawl before you can walk and you have to walk before you can run.
I recently purchased a pre amp kit and 7 watt amplifier from velleman. These kits are for like kids to learn I think. The skill level is 2. but I want to connect them using the same power supply.
1. The pre-amp power supply needs to be 10-30vdc/10mA and the power supply for the amplifier requires a power supply of 8-18vdc/0.5A. I have found in the far reaches of my attic a power supply that is rated output of DC 12v / 2A. can I use this power supply to run the devices simultaneously?
2. Also I have to cut the tip of this power adapter off to connect it to the devices and use it to power the device. The power Adapter output again is DC 12V / 2A. as this is my first real project I'm a bit worried that I might be entering the realm of danger. everywhere I read says that 2 amps is more than enough to kill you. I understand that I am opening a can of worms here, but I can never get a straight answer. what happens if I plug that adapter in and touch the wire wires with each hand will it send electric death though my heart and body? I know enough to make sure every thing is soldered properly and not to touch the device while its plugged in and if I do have one hand behind my back. but I plan to make this a travel guitar amp and well when the guitar is plugged into the amp the operator becomes part of the circuit because the strings are attached to ground. Is there a chance that if I design this makeshift guitar amp I will kill myself attempting to play a guitar though it?
Thanks in advance folks, I have my favorite Music, Amps, Guitar, forums. that I go to I hope to make this my electronics home forum.
