Break down of pin connectors

<< < (2/2)

Folsom:
I'm saying some of the heat might be from a poor connection. It's like how a small wire will be hotter than a bigger one under the same load.

S Clark:
I get what you're saying.  Except George seemed to know exactly where to go on this.  I'd put money that it's a bad idea to put a heat generating diode into a pin connector that isn't designed for heat.   My guess is that it was a poor design choice by George that was fixed in later models.  But to his credit, I was able to avoid the whole over the top box building to keep the apes at Fed Ex/UPS from destroying what ever is inside.  I can't tell you how I was dreading boxing and shipping that amp.

Plastic connectors like that are used in auto engine compartments for years and I would think they go through much worse conditions than in an amp. I wouldn't think the auto industry uses anything better.

Glad you fixed your problem :thumb:

Yes, but I've never seen one plugged into a component with a heat sink.  You don't see a pin connector on a block or exhaust.
