Sound Code System Amp Specs??

SCS Specs

Sound Code Systems amplifiers:

Mo. 2600A 350 wrms @ 8 ohms 600 wrms @ 4 ohms, 1200 wrms mono
Mo. 2450A 275 wrms @ 8 ohms 450 wrms @ 4 ohms, 900 wrms mono
Mo. 2350A 260 wrms @ 8 ohms 350 wrms @ 4 ohms, 700 wrms mono
Mo. 2150A 100 wrms @ 8 ohms 150 wrms @ 4 ohms, 300 wrms mono

Distortion = .01% THD/1 KHz, .025% IMD @ full power/8 ohms
Freq Response +0/-3db, 10Hz - 175KHz +0/-1db, 10Hz - 90KHz
Slew Rate = 70v/microsec
S/N Ratio = 95db, unweighted
Damping Factor = 350
Input impedence = 25Kohm/unbalanced, 7kohm/balanced

I have the schematics and parts list, if needed.

Hello Rick,
I see that you are in pocession of the SCS 2450a technical inforformation that I have searched high and low for. How would one go about getting such info??
I am new to this forum and I realize your post has some ace to it but I hope you still check in from time to time as you seem to be the only one on the net that has this info
Thanks

I own an SCS ( sound control systems inc. ) model 2450a amplifier and noticed this post .
Might anyone have the parts list for the power supply.
After 30 years the thermister connected to the main resettable fuse has turned to toast and obliterated any ID codes making it impossible to determine the specification value of the thermistor . I took a reading and the ohm meter is reading too high at 90 ohm .

Judging from the fuse 8 amp rating I suppose the max full constant duty spec for a thermistor is probably 5 to 6 amp maximum . The average thermistor of that rating looks like 8 to 10 ohm .
Is a power supply schematic with specs available from somewhere out there ?

kind regards Jon

Rick do you still keep the information? how can I get a copy for the 2350 ? thanx.
 
I bought one (2350) a few years ago, sounded ok when I bought it when played at low levels. When I got it home, a considerable distance, it had blown gates in the outputs, and upon further investigation, the zobel components were melted almost to a puddle.

I never did find what the input impedance was from any literature. It sits on a shelf now.
It might be a candidate for the Bob C. DH220C boards if and when they materialize.
 
Well, I'm only a couple of years late responding. Sorry about that. I have attached all the documentation I have for these amplifiers.
I currently have 5ea. SCS2350As, 3 ea, SCS2450As and 2ea. SCS2600As (You could say I'm a fan of these amps.) Of these 10 units a couple of them need repair.
In addition, I was able to purchase 4ea. of the stuffed PCBs (Common to all SCS models) from the last company to hold the manufacturing license in Garden Grove, CA.
In stock form I felt that the SCS outperformed my other amplifiers, including a Hafler P-7000, Carver TFM55X, Crest P-3500 and Crest CA9. By upgrading the electronic components on the PCB and replacing the fan with a quieter model, you'll have a high current MosFET power amplifier worthy of audiophile status.
My audio system is in constant evolution, but I currently use an upgraded SCS 2600A to drive my Magnepan 2.5r speakers. I'm considering bi-amping the Maggies at some point, but trying to finish my FET preamp project at this time. You can see my upgraded and repackaged 2600A in the attached photos (On top center above the monitor.) Hope this helps.

The input impedance can vary depending on the specific amplifier design and can significantly impact the performance and compatibility of the amplifier with other audio equipment.
