Unbelievable this design being published in 2012!
Str.
Well my final word on this matter! The reason it's still being published is the fact of being a learning aid (well for me). Yes it's old design but a circuit diagram that was shared and with many people who also tried to build them (some successful, some not) and people shared their experiences with it.
Having never really built anything like this before, it started with a circuit diagram that was published and some people comfirming that it worked and produced a signal that could be used and unlike some circuits I've spent many hours on that were found on the internet, once I had built never worked and were never going to due to design.
I was given details on a easy layout to follow when building it on a copper board that allowed me to change out components to experiment with. I gained a good understanding of the stages and picked up knowledge by speaking to others on many things like, test point to check when I found things weren't working or swapping out components to see if things improved or got worse.
Once I had "what I" believe is a working copper board layout I wanted to see if it was possible to make a PCB version. I have never used PCB software like this or had any prevous experiences so found it a challenge. I was able to produce a PCB with the help of someone and a few boards was made. Yes, at first it wasn't perfect but networking with others and them giving me their opinions and suggestions to try different things to make it sound better. These things made small improvements but again these things didn't fully solve the some problems but after walking away from it for abit and a clearing my head I was able to spot something after looking at all the different variations of circuit designs that somethings were missing.
This latest PCB version I ordered to get made "to me" sounds alot better and produces a good output. No its can't be compared to a commerical broadcast transmitter but for the cost and through hole components that many people still enjoy to use and build with like me works fine. I'm not kitted out for surface mounted tech yet and yes it's the future but how many hobbist start out with SMD off the bat!
The whole time I've been mucking around with the Corsair it has taught me alot about circuits, fault finding, testing, PCB design to getting it manufactured and whats involved. I now appriecate the research & development that goes into projects and I have met some decent people along the way too. It's given me confidence to keep trying even when things fail.
Oh if your wondering here's the image of the Corsair and audio limiter/compressor PCB's. It will never get a true test as I don't have the equipment to carry that out but wanted to state what someone can achieve having very limited knowledge!
