Ok, fellas, Here’s what I was able to track done on this “ULTRA” animal, as there is little info on the net. I was actually trying to find the original owners manual on the net. I couldn’t find it, so I called “Greg” at US AMPLIFIERS (626) 833-2177. Greg told me there is NO USER MANUAL!!!
Greg told me the “ULTRA” was produced from 2003-2004 and ONLY
50 WERE EVER MADE!!!!! This is a TRUE COLLECTORS AMPLIFIER and a HUGE part of the hobbies history.
Here’s the deal, straight from “Greg” at US AMP.
4- 8 gauge VCC lines
4-8 gauge Grn wires
400-600 amp min. input
2 channel amp x 50W per
1/2 OHM Stable
Actual Total Wattage is unknown. Estimated 6000W
It is actually 1 amp with 2 power supplies. IT IS NOT 2 AMPS!!!! Although it has 2 boards, and both have their own power supplies, one is the positive rail, and the other is the negative rail. The AMP is actually considered “A/B Full RANGE”. The Amp has a HIGH dampening factor, hence making it produce “High Sound Quality”. Most used this amp for competition in the SPL category as a cheater amp.
Greg competed with one of these 100HC “ULTRA’s” years ago and ended up selling his in “FAIR” condition. He ended up getting $1500 for his “ULTRA” many years back, due to its “Ok” condition. The original cost of the amp was over $2000.The one I purchased is probably a 9 out of 10, as far as condition, and never used or abused. As stated in the
ebay add, it was a “closet queen”
Probably going to put it back on
ebay to sell as its wayyyy to much power for what I need…Before I do that, I will be attaching pics here in the near future, so please check back to this thread
Regards,
XTC
