Re: [Repeater-Builder] Cheap "Tunnel" Heatsink

[John J. Riddell]

Brett, I have a copy of a commercial "Load Bank" which is nothing more than a bunch of large resistors in a case controlled by switches. I'll dig it out and scan it for you....   These people get $3,000.00 for this package !  I have the stuff to build one and have about $75.00 invested so far.....   73 John VE3AMZ ----- Original Message ----- From: Brett To: Repeater-Builder@yahoogroups.com Sent: Saturday, February 11, 2006 9:28 PM Subject: Re: [Repeater-Builder] Cheap "Tunnel" Heatsink Hi guys does anyone have that circuit diagram I need to build one to test 12 to 60 volt supply.

You could vary the Amp Load on your power supply using a variable pot control. Gary  K2UQ   YAHOO!
