Plenty more where they came from :-) Didn't you know that I spent time soldering as well as farting?

Default Current Project - Discrete Amp

Here's a plot of my current project. It's a discrete amplifier. JFET input, diamond output stage. Targeting peak output of 1W into 8 ohms. Designed for ±8V power supplies.

The bias is very squirrely. I need to go back to my sims to find a less sensitive operating point.

Here's my Corda HA-1 DIY kit, taken with a Kodak DC3700 that I borrowed from my mom. Unfortunately it's an entirely point and shoot camera and thus has no proper photographic controls at all, the pictures arn't all that great.

Wow, some of you guys make some real works of art. I'm just happy when mine work
Here are my humble projects so far:
Millett amp that was my first attempt.


A Bottlehead Seduction Phono stage.


A Mint amp my Son & I made.


My latest Project A Morgan Jones Earmax Clone.

I will be building a Bottlehead S.E.X. amp next.

More of the stuff I've built. Lost many older pictures of stuff I've built when my previous harddisk crashed. I don't think I need to explain what amp this is.

Performed some modifications on the Corda HA1 MKI for a friend.

Solens in the x-feed circuit, OPA637's, Cascode Jfets Class A biasing, Blackgates in power supply etc...


Pre-mods:





Just the opamps and buffers swapped. Along with Class A biasing.




The power-supply caps swapped out. Bridge rectifier changed to discrete Fast-recovery diodes:




Completed:

My very first amp.. Based on the Meta42 schematic. I didn't even have proper interconnects (and still don't) or a desktop CDP then.











A massive mess on the inside:
