Title: Finally I decide to use TURRETS ON PCB approach.
Post by: BOWMusic on September 16, 2021, 07:41:03 am

Finally I decided to use hybrid approach, turrets on PCB. It turns out well good, it's like a 3D surface mount for big components, don't need a service window or remove the board to repair and modify. Everything is on the top.can't wait to put some resistor sand caps on it.

Very cool.  I always felt this was an underutilized approach.  I've got a pcb for a more complex amp project on the bench right now that I wish had been designed like this.  There are a few components on the power rail that there's a high chance that I'll have to swap out and tweak as I'm modifying the original design.  Unfortunately, the holes present aren't the right size for turrets.

Makes changing components later a breeze and far less damage to the substrate and runs. I would be a little concerned with the swaged part of the turrets being a little close to the conductive runs.
