Nahash5150 10,999 Posted April 4 Posted April 4 This is for @davidc. A typical dirty and rusty specimen! Decent shape. No severe burning so that's a great start. Tear down. Lots of dirt. I will take care of that rusty fan grill, and install a new quiet fan and turn down the speed to make it QUIET. Chassis cleaned up and tested. Had to replace some bad transistors. Typical. An LED sensitivity switch was requested, so I'm cutting one out here: Everything cleaned and rebuilt! New fan and restored grill: All back together: Best sounding 750W per cannel amp ever! 1 3 2

Brian K. Totten 435 Posted April 5 Posted April 5 Its the fine, exquisite details, of a service or restoration that matters! I am not sure how anyone can look at this thread, then say, "I am sending my amp to "Bob-the-builder" and expect this level of service, not to mention the killer warranty! Nailed it! Yall are superb! 2 1
Community Admin AndrewJohn 10,970 Posted April 6 Community Admin Posted April 6 Super nice, @Nahash5150, Love seeing the process in images. @davidc is gonna' love this. Curious to ask, what does the LED sensitivity switch do? I did look on NelionAudio.com for a mod option description - may have missed it. Thanks in advance. 1

The LED sensitivity switch will allow the LEDs to 'bounce around' or respond, at lower volume levels. You really have to be hammering it to get the LEDs to respond from the factory. Here's a comparison: Here's the LED power estimates into 6 OHMS: Indicator - normal / high sensitivity LED 1 - 20W / 1W LED 2 - 42W / 2.5W LED 3 - 72W / 4.5W LED 4 - 185W / 11W LED 5 - 330W / 20W Sorry - I don't have it on the site yet. 1
