Turned out to be a faulty input transformer! I’ve got my mouser cart saved with the parts I used if anyone is interested! lots of things on the original BOM has been phased out. Thanks to hairball and serpent for this awesome build!

Kprellz,

I'd be interested in seeing a copy of your Mouser BOM, if you don't mind? 

Thanks in advance
Greg

I also added a switch to the 604 1/2 w output termination.  So know I can switch that in and out from the front panel as well. 


Hey guys, can anyone explain how to implement this loading/termination mod?  The old la3a units had terminals on the back, the SA-3A doesnt.  So would I just strap a 604 1/5 watt resistor on the (+) and (-) output jumper pins on the board or am I missing something.   (see pic attached)
