Saz-3500

Jacob, Did you spec the wires instead of rails?? I like it.
Yah - I've wanted wires for a while. Most importantly to replace where the transformer leads jumped to other parts of the board (like from the transformers to the rectifiers) - instead the transformers just go into the board and then a wire jumps over.

Over the months / years the transformer leads can vibrate and rub off the enamel and short out at that point.

I have also seen some occasional problems with solder on the larger solid rails.

We took alot of stuff learned on the 3000s over the years and applied it to this model.

 
My initial testing:

---

10,320 watts from my pair @ 1.5 ohms each actual impedance after rise, starting at 0.5 DCR

5160 each

---

Little more testing... dropped it down to 40 Hz which is ~1.3 after rise :

11,470 watts

5735 per amp

---

17.9v @ rest -- have not measured my voltage drop.

Power output is right on par which what I have expected - with a larger battery bank I bet I could get even more from them.

 
We picked up a few of these yesterday.

Saz-3500d measurements. Heighth and width are the same as the rest of the saz series amplifiers.

Case is 26" long

Including the rca termninals and power terminals it's 27.25" long.

Width is 10" at the mounting feet.

Heighth is a hair over 2.25"

I got a little testing done. These are "unofficial" results. Until I use Jacob's equipment I won't consider it official. I did not use peak hold on my meters (and yes they are true rms). Instead I recorded my 3 meters all in real time with my camera reading ac voltage output, ac amperage output, and dc voltage input at the amplifier. Then I slowly rolled into the volume to prevent spikes and held it for 5 seconds so the readings could level off.

Results:

2,318watts @ 2.9ohms after rise @ 13.7v after drop.

4,040watts right around 1ohm after rise dropping to 11.3 volts.

Again, these were not peak hold measurements and these are unofficial results. I'll get some official results from Jacob's equipment on Monday or Tuesday. That way all our testing will be uniform from the same meters.
