Mini A Board Run - Page 3

BrianGT · 23rd March 2006, 01:10 PM

My Mini-As are running good

Here is the new SMD Mini-A layout that I am working on. It is based of the through-hole one, and accepts balanced inputs:

The board is just a bit smaller than the TH version, and the SMD resistors mount on both sides of the pcb. The resistor designations are the same as from the TH version:

Here is the through-hole board for comparison:

SMD for sure. !

Here is a PSU design to go with the new miniA layout:

The idea is to create a pcb set containing 2 PSU boards and 2 amp boards, and scored like the last set for easy separation. 6"x6" total size for the pcb set.

I like thru hole better too.

1) more choices and can source locally if necessary.
2) easier to work with.
c) I already have a bunch of thru hole stuff on hand
4) easier to work with

Brian's previous thru hole mini/30 boards left very little to be desired.

1st) thats Mine & Brian's Boards, i helped.
2nd) the mini a SMD can be sourced out all from digi key all parts are from digi key.
3rd smd mini a's sound better.

When i get a board made ill build a pair and pass them around any one interested in listening to a set.

The first smd Mini A's ( the ones that got all this going ) Sound better to me than the through hole one's.
