"a simple 2-way: Alpair12pw + Alpair7PeN

Mario, in case I didn’t mention it before, nice work on those. Out of curiosity, which model of Marantz receiver is that? I’ve got a bit of a soft spot for the later ‘70s series 22xx series.

....aw shucks Chris...🙂

The Marantz is a 2225 that I restored many years ago...it was great fun but next time I restore a receiver I'm not re-capping any of the FM tuner boards...much work and no improvement....it sounds great though and I have a softspot for the series because I couldn't come close to affording one in the 70's when I coveted them in my teens.

I'll light it up in the background of my next build pic.....microcastles 45 degree angle w EL 70's...wood's been milled but a bit burned out after the pre Burning Amp rush and will get to it in the Spring....

Norman,


See Scott's comments posts 7 - 14 in this thread regarding crossover design.


But btw, I did try 1st order hi pass by yanking the inductor and leaving just the capacitor....it sounded worse and wasn't a subtle deterioration in sound quality...I soldered it right back in...
