View Full Version : bi-am-/tri-amp my S7r's with 2405's - Pioneer crossover broke :-(

I built my S7R's in 1970, I assisted in managing a small high end stereo shop where i got great deals on Audio Equipment. I chose the Pioneer SF-500 electronic crossover, not too expensive and had the 3 frequencies I wanted, worked well. :D (using 1970 vintage Marantz 250 with Marantz 33 preamp - 2 - Marantz 1030 amplifiers for LE-85 and 2405's)

Only 40 years later, it doesn't work now - anyone have a clue where I might get it repaired? I am assuming Pioneer won't even mess with it. :blink:

I just may sell everything, its all in mint shape, still undecided.

Should be easy enough to repair.

Any technician with basic level can fix this with the schematic.
There's nothing in there.

Before you abandon ship, if you cannot find anyone, or you yourself don't feel up to the repairs, you might consider the Ashly XR2001 (http://www.ashly.com/xrseriescrossove.html). I'll bet it sounds at-least-as-good as that trusty old Pioneer, and they are easy to set-up and reliable. There's one on eBay for $175 right now. (btw - everything on eBay seems to be selling for way cheap pricing these days...). Let us know how you go...
