Chck the post above yours..

Pete, I have a Carver PT 2400 that will do 3,000 bridged into 4 ohms. I can send it to you and if ya like it, you can send me 600.00 and we'll call it good...

Stereo----750 into 8, 1200 into 4, 1500 into 2...
Bridged mono...2400 into 8, 3000 into 4...

HOLY SHIT...

Thanks laatsch55; I will keep your amp in mind, I will look for a schematic and more specs. The RCF drivers have a 1500 Watt "AES" power rating. So I am looking for an amp that can get the most out of them. In hind sight, should have spent the bucks on the JBL drivers.

Hookay...

What is AES??

RCF claims to adhere to the test methods described in the above pdf

Pete, have you heard of Epiphany's?

On the subject of bridging......have you read Rod Elliott's treatise on the subject? One of these days I'm gonna bridge a PL 400 or 700 just to see it done..

...And more info on CS800 vs. PL700 is here: http://forums.phxaudiotape.com/showthread.php/3293-Phase-Linear-and-Pink-Floyd/page9 - post 86 with links..

I am not seeing a lot of info, just tidbits. I would really like to learn more about the CS800 since I have a super clean one sitting in the garage and I want to use it but I want to know what can be done to make it even better

I thought you said that was a no no so I will be watching to see how you make out

 

[laatsch55]

It is a no-no. That's why it must be tried...

Ok I see what you mean. My CS800 is far different looking. It pretty much looks like what all Joe's control and backplane boards, no TO3 circuitry. I took the top of this morning and cleaned out a bit of dust in areas, not much at all. I like the flow through design over the transistors with the fan which is wicked quiet. I took a few pics and will post them up in a bit. Looks like the boards were matched perfectly and the tranny has a notation of 101 so I am assuming that's 101 volt? The caps have a large board bolted to them, odd looking bluecaps, very short and fat. I like how the amp is set up, almost like modules

 

[Northwinds]

Both boards have the same notations

Northwinds CS800 is a repackaged design of the original. Its still my contention the original CS800 was a BGW750. Seed this link

Yep, I agree. I was just showing my more modern example that they corrected whatever of the old design and has the DDT circuit and better DC protection. I think I want to double the capacity of the stock caps. Maybe a pair of 33000uf short fatties

Here ya go Pete...

Pete I could also put it on the AP to verify performance..I have in the past and it does 838 watts into 8 ohms. Never tested into 4 or 2, but I can....
