New SAE-1200D v.2 Testing

[sundownz]

I got the sample of my v.2 SAE-1200D in... testing is going quite well. Honestly... I need to change the part number to SAE-1500D on these *laughs*

TEST 1:

1 ohm nominal @ 60 Hz

1440 Watts

54.6 V

26.4 A

2.07 ohms

** Over rated power at 1 ohm nominal with 2x rise

TEST 2:

1/2 Nominal @ 45 Hz

1750 Watts

49.6 V

35.3 A

1.4 ohms

TEST 3:

1/2 Nominal @ 50 Hz

1840 Watts

Popped Fuses (too much current draw)

Replaced fuses amp is okay -- I don't suggest 1/2 ohm daily but to get power testing somewhere close to 1 ohm actual I wired it that way with a known rise.

Some pictures vs. the v.1 SAE-1200D :

NEW on the LEFT

OLD on the RIGHT

looks like alot less internals and great power output

[Decaf]

tested voltage?

Internals are actually almost identical... the old board just looks crowded from the black lines on it and the extra raised bars (single sided board needed them). Many of the small parts were also centralized to the one corner (upper left of new board) instead of being spread around the board.

The BIG difference is the new board is double sided -- almost all of the problems with the v.1 models that came back related to vibration breaking solder connections. The double sided board has solder all the way through the eyelets and not just on one side -- much more rugged.

tested voltage?

14.4v w/ 80-amp power supplies on board and 4 awg power wire.

I didn't measure drop but I'd expect it to be into the mid 12s on the 1 ohm test and mid 11s on the 0.5 ohm test. based on prior testing I've done on my bench.

Still the mysterious black box in there, presumably the output drive?

Nice power out of it

i like how v.2 board is layed out much better

Yah, it's the driver card -- these guys encase it in epoxy.

It's very rugged... I never had one fail on a v.1 SAE-1200D model regardless of what happened to the amp. Has large discrete parts in it vs. smaller SMD components.

how clean is the power compared to the saz line??..

[sundownz]

As long as your are playing this amp @ 1 ohm it will sound very much like the SAZ line.
