Due to a shoulder problem, my playing is sidelined for up to a year...
So, I thought I might pass the time, by doing some DIY stuff.
First of all, I want to build very simple mic preamps.
I want to do things like, try different IC's out, different values of this and that, wire a transformer in here and there.
I dont want prebuilt kits, ( i have built those before JLM stuff) basically, its just going to be a little sideline, and I figuire I might learn a thing or two.
So I thought, I would need some sort of bench power supply, adjustable.
Breadboard etc
anyone got any suggestions, I went to my local Jaycar and got a catalogue and started reading...
If you have a bunch of this stuff you want to sell, I would be interested.
cheers
Wiz
( i already have things like multimeter, soldering iron etc)

Re: power supplies, breadboards etc
really, no one got a bench power supply or breadboard to recommend? where did you guys get yours from?

I've bought a few bits from this online store from China. I've seen the same ones as on this site rebadged and sold for a lot more here in Oz

Re: power supplies, breadboards etc
ITS ALIVE!!!!!!
I know for some of you this will be ... a yawn....
But I gotta tell ya, I am pretty excited.
This is as minimum it can be for a mic preamp.
ACDC supply from JLM supplying +- 15VDC and a INA217 mic preamp with two 2K2 resitors strapped across the inputs
and a 100 ohm resistor across the gain.
I just recorded a vocal with it...
I couldnt be more tickled.
Now, I will start adding things to the circuit such as input protection diodes, and DC blocking caps.
Then the next stage is dc offset and balancing.
Then I wanna try input and output transformers.
and see at each stage what the changes in sound are like.
I also want to try different types of resistors and caps and see how they impact the sound.
How does it sound now I hear you ask?
Really clean. Noise floor is pretty damn usuable, I havent checked for DC offset or anything like that.
I couldnt stop giggling like a little kid 8)
