Default Inductors in T Amp

I want to build air core inductors for my T-Amp.
Does anybody know how many wire turns, wire diameter (in mm) and air core height and diameter (in mm)?

My English is not so good but I'll try to explain...

First thing is that the shortest (possible) signal and/or power supply path is THE MOST IMPORTANT thing here. Like for the GainCard/GainClone amp. Again THE MOST IMPORTANT thing. If you fail here and leave only few millimeters of wire more than it's necessary result will be not so good.

You need good magnifying glass. I have two of them.
Big one is 7.99 eur and small one which is part (eyepiece or ocular) of toy microscope set. If you want you can find this toy microscope at
Toys "R" Us Ltd.

Concord, ON L4K 4M5
Maidenhead Berkshire UK

or

Toys "R" Us AG, 8305 Dietlikon
Koeln, Deutschland



Without this and good soldering iron you can't do much. But with this you can put two 1000-2200uf/16-25V caps close to TA2024 as TRIPATH suggest (see picture )

Then you need SLA battery and battery charger

And keep wires between TA2024 and battery as SHORT as posible

Next replace DIODES.
Find MBRS 130 T3 SHOTTKY 30V 1A diodes. Or other suitable Ultra Fast Recovery diodes

For maximum effectivness these diodes MUST be located close to the output pins and returned to their respective PGND tm

This means try to move new diodes closer to TA 2024 chip.

... then you need some SODER-WICK from Chemotronic or any other company AND minimum 100 m of silver wire, if possible

and here you have link about soldering SMD components...

When you finish reading this you will realize that soldering smd's can be easier than we think...
