Default Hello from mid-west USA

Hi all on the forum, have looked around the forum some. Have liked what I've seen so far.

About me, I have some electronics back ground, 7 years at hybrid manufacturing facility as a tech, then seven years as a production technician at a TV factory. Recently had gotten away from the electronics scene, but now I am back again building some circuits at home.

My latest project is a low power portable electric guitar amplifier. Have made some decent progress with building the circuit on a breadboard. The idle current with no signal is a bit less than 10mA. Max current with audio input is around 70mA. Am powering with 6 AA batteries so far. Changing current into audio, have a speaker about 2 inch. out of a busted speaker cabinet, you know what happens when those cheap plastic things fall off your TV . Being the pack-rat that I am, such items get saved for future projects of course.

So now am getting ready for the hard part, transfer of parts onto a perf-board. I spotted that a diode in my bias divider was not a regular diode, it was a zener-diode. So now am going to have to check into what differences this makes on my voltage drops.

Have any of you, ever had parts get mixed up in projects before ?

Hello and welcome to the forums. I think we all have had a few mix ups over the years.

It is tradition in all of my circuits to reverse a diode or capacitor. Caps are spectacular when reversed....

Welcome to the forum...

Smile Thanks for the welcome and update

Thanks for the welcome.
Got my gain circuit installed now on the breadboard, sweet. Check my video out, if you want to see & hear it.
