    5 Orion HCCA G4 225(2),250,275

    Those were my G'4 I think? They have changed hand a couple times I think. I sold them to Jason a couple years ago. Wouldn't mind taking the 275 back. That and my Studio 500 LE are 2 amps I should have never sold. PM me a price minus shipping. I know what that will cost

    FS: Sony Mobile ES 7547 AKA "Big Red"

    I'm only commenting because you asked me to... The amplifier is rated at 75W x 4 at 4 ohms and 0.04%THD. The amplifier is 0.5 ohm stable, but only for channels C/D. It accomplishes this by paralleling the output devices via relays. So rather than being "bridged", the channels are paralleled in mono mode. The outputs are interesting devices. They're MosFets rated at 100V and 70A; a great combination. The rails are +/- 28V in "high voltage" mode. This gives you ~150W into 4 ohms. You can see where this is going. At 2 ohms and in "high voltage" mode, you're still at 28V rails so ~250W per channel (that's 250W x 4) is not unrealistic when playing music (as opposed to test tones). At 0.5 or 1 ohm, the amplifier should be switched into high current mode, because you will almost certainly reach an overcurrent situation quickly at 28V rails. When switched into high current mode, the amplifier halves its rails to 14V so as not to trigger an overcurrent situation. So you're limited to the same amount of power. So what's the point of having the 0.5 and 1 ohm capability if you don't gain anything? It's partly marketing. People see that and think "superior amplifier" when it's more "bait and switch" and "LOL..." to us engineers. You aren't gaining anything but flexibility, which is valuable in its own right - but don't go changing your woofers just because it can drive 'em. The other part is stability. The output transistors can't drive sub 1 ohm loads without blowing up, so Sony implements some extensive overcurrent circuitry to force you to switch into another, lower voltage mode. "High current" sounds better than "low voltage", but it's the same thing in power supply engineering-land. Another thing - there is a sh*tload of SMD circuitry under that "sparse" board. It always kills me when some chucklehead opens a Japanese amplifier on AmpGuts.com and comments on the low parts count. It's a solid amp. If it wasn't so huge, I'd have no problem owning one. I bet it sounds divine.

    Good way to describe it would be a marble like finish. Pretty cool looking I think.

    FS/FT: Earthquake 40UHC Gold RARE

    $325 shipped. Not a penny lower. Dont even ask. Hell of a deal for a RARE A/B powerhouse. Not bad on electrical too I guee. A guy on DIYMA sold his a month or two ago and said he had only "one big battery" and didnt have any issues. Im going to run hook it up next weekend, so if its not sold by then, I will be running it till it is. Till then, its on display in my living room

  11. Item(s) for Sale: For sale in great condition is a Sony Mobile ES 7547. BIG power 4ch as some of you know. Its a big case amp so you better have some room. But its worth it for the great sound quality these old Sony's produce. This amp can do 250x4 @ 2 ohms continuously, not peak. Also can use any ohm sub on the rear channels as it is switchable for 4 or 2 ohm and 1 or .5 ohm 100 AMP Fuse Item(s) Description/Condition: Exterior 9.5/10 Function 10/10 Price: $250 shipped OBO Shipping and Miscellaneous Item Information: Shipping included in price from 98057 Item Pictures: (List pictures in this section, 1st picture should be your username/date if you have less than 10 positive feedbacks with the i-Trader system or less than 10 references that you have sold to in the past.

  12. Item(s) for Sale: (1) Earthquake 40UHC Gold. Good condition. All fins are straight. Couple scrapes on the fins missing some paint, other then that it looks great. BIG AB power! 1500+ at 1ohm. Better have good electrical! (1) Sony Big Red Mobile ES. Great condition. 9/10. LIGHT scratches. Probably wouldnt show up on my Iphone if I use it for pics.
