Here is A amplifier with 2n3055 transistors on its output for those of
you that are looking at doing a bang for buck amplifier with all those
2n3055 lieing around that as most electronics guys think when they look
in there old box there must be something I can do with this stuff.

This is an easy to make power supply which has stable, clean and
regulator 0-28V 6/8 Amp output voltage. By using two 2N3055 transistors
we become more then 2 times the amount of amps then the power supply
delivers, making it real though to brake ;). Although you could use this
design to deliver 20 amps (with almost no modifications and with a
proper transformer and a huge heat sink with a fan), I did not needed
such much power. Make sure you mount them on a huge heat sink, as the
2N3055 transistors can get very hot at full load.

Thank you so much for this share. You should upload more schematics of using transistors as amplifiers.
ReplyDeleteThank you for the comment. I'll look for more transistor - amplifiers and post it soon.
Deletewhat is q3?
ReplyDeleteHere is a way to solve a problem that drove me crazy for months until I found a better way. Doing voice over work often requires me to break one long file into several small ones, saving each on with a unique file name. It doesn't have to be a long and tedious chore. Here's a way to semi-automate the process to get it done in a fraction of the time using an audio editing program called Adobe Audition. Best Car Audio
ReplyDeleteThe the next occasion I read a weblog, I really hope so it doesnt disappoint me around brussels. Come on, man, Yes, it was my option to read, but I just thought youd have some thing interesting to state. All I hear can be a lot of whining about something that you could fix if you werent too busy searching for attention. Mega888 game client download
