I got a used HK AVR 1510 for him from Facebook marketplace. It shows it is rated for 75 watts per channel but the thing was probably only 5 or 6 pounds. It was really, really light. My brother's old Sansui receiver from the 80s has to weigh 60 pounds. I know, class A vs. class D. I'll check the settings when I visit him next.
Klipschguy, I have a question. Why do you prefer the 'industrial' caps versus 'audiophile' caps? I dabble in crossover design and DIY speakers and I have a lot to learn. I would love to hear what you've discovered by using different caps.
I will admit that the way speakers work in general is almost like magic. I don't understand how or why they work but there is something so special about great sounding speakers. Add to that your source and amplification as well. It's a team effort. You play the right music on a great set-up and it can lift your spirits, help you relax, get you crunk, or put you 'in the mood'. It is literally a disc shaped thing flapping back and forth in a wooden box and it somehow changes the way your brain works. I don't know what else to call that but magic. I'm hoping I can restore some of that magic for Tommy and his old Cornwalls.
Thank you all for your help with this.
