The Cerwin-Vega A-1800-I is a power amplifier in the solid state amplifier category. It was manufactured from 1975 to unknown.

David Cole (November 18, 2012): The cerwin vega A-1800 one of the first high powed amps in the 70s this amp would put out 375wpc and would was built to last forever this amp had 10 out put transistors per side and huge heat sinks and beer can size filters the unit was made for disco clubs and the movie Poseidon Adventure an earthquake in sensoron the amp sold for about $2.700 dollars in the seventy's they had been been considereigh to be highend in the audio era not many people remember cerwin vega for power amps just speakers but they put out the amp to power there speakers and it was an awesome powerful sound that no other could duplicate the clarity and vocals of this Cerwin Vega power amp was and is one of the best amps ever made in the USA the separation of the left and right channel was awesome sounds on the left side stayed on the left sounds on the right side stayed on the right there was no mono sound whatsoever we need to bring back this find audio of the 70s vintage Cerwin Vegas are made in the USA the new ones are made in china and they sound like garbage just like everything that was good about the US has been sold out to China and quality has been reduced to less than average.

THOMAS (November 18, 2012): hey! guys vintage cerwin vega power amplifiers rock i got one off ebay for just $300 and i had to have the solder joints re done on the input board they got hot and blew my speakers cost me $180 to fix but 1 year later it still sounds like new i have the A-3000i with vu meters very very nice amp high power clean bass beefy highs no EQ needed for cerwin vega vintage power amp.
This thing will be here working for 30 more years now i need an A-1800 to add to my vintage audio still looking for one ebay is dry on vintage working cerwin vega amps i hope one turns up soon.

DAVID LEE COLES SR (January 29, 2013): WELL WE HAVE HAD A GOOD TIME TESTING AND PLAYING POWER AMPLIFIERS AT MAX VOLUME THE MCINTOSH FIRST AND SECOND GENERATION BLEW ALL THERE OUTPUT TRANSISTORS SOME BURNED UP WITH FIRE COMING OUT OF THEM TAKING MY SPEAKERS WITH THEM.
WE ALSO PIONEER SPEC 1 AND 2 THE SAME SMOKE THEN FIRE.
IT WOULD SEEM THAT SOME VINTAGE AMPS GET HOT AT HIGH VOLUME AND BURN OUT OVER TIME THIS IS DUE TO CHEAP PARTS THAT DO NOT LAST.
CERWIN VEGA VINTAGE POWER AMPS JUST GET BETTER WITH AGE LOUDER AND JUST KEEPS PUMPING THE PARTS INSIDE ARE HUGE AND WOULD SEEM TO BE BULLET PROOF 14 HOURS OF HIGH VOLUME IT JUST GOT LOUDER MY STATEMENT IS THIS THE BEST BEAST EVER MADE TO ROCK THE CLUBS AND HOME WAS THE OLD VEGAS 1970 UP TO 1980 TOP OF THE LINE AUDIO THE BEST POWER AMPS IN THE WORLD AND THE FACT OF THIS IS THEY ARE STILL HERE IN CLUBS AND HOMES ALL OVER THE WORLD.
I HAVE HAD 4 IN MY LIFE TIME THE A-1800 AND THE A-2200 NOW I JUST PICKED UP THE A-3000I THE KING VEGA AMP WITH 14 OUTPUT TRANSISTORS 60 POUNDS OF STEEL AND MAX OUTPUT 1000 WATTS BACK THEN 1000 WATTS IS LIKE 5000 AND CERWIN VEGA MADE THEM TO DO IT FOR EVER NOW OVER 42 YEARS AND STILL WORKING STRONG MAN IF YOU CAN FIND ONE SEE FOR YOUR SELF.
BUT THIS IS ONLY THE USA MADE VINTAGE CERWIN VEGA POWER AMPS NOT THE NEW CHINA MADE JUNK STAY AWAY FROM THAT THEY JUST PUT THE NAME ON SOME LOW GRADE JUNK THIS IS NOT THE CERWIN VEGA OF THE 70s EBAY MAY HAVE SOME KEEP AN EYE OPEN FOR ONE YOU WILL SEE FOR YOUR SELF....

SAMMY AUDIO (March 21, 2013): PLEASE NOTE THAT ONLY THE VINTAGE CERWIN VEGA POWER AMPS ARE THE ONES WE ARE TALKING ABOUT IN THIS FORUM ONLY THE A MODELS
NOT THE CV MODELS ALL THE CV MODELS OF CERWIN VEGA ARE NOT THE VINTAGE UNITS.
ALL OF THE FIRST MADE VINTAGE POWER AMPS BY CERWIN VEGA WILL HAVE AN (A) THEN THE MODEL NUMBER OR AN (M) THEN THE MODEL NUMBER MANY PEOPLE ARE BUYING THE CV MODEL OF CERWIN VEGA AND THEY ARE MADE IN CHINA ONLY THE ONES MADE IN THE USA ARE THE TRUE CERWIN VEGA VINTAGE POWER AMPLIFIERS......

davidleecoles (May 26, 2013): Information is needed on the Cerwin Vega a1800m vintage power amp.
This is one of the vintage CV series of solid state power amps from the 70's the watts are the same as the a1800i this 1800m had four speaker outputs in the rear and had selector buttons on the front along with VU meters and volume controls.
This amp is 225 to 250WPC at 8ohms and 325 to 350 at 4ohms the a1800m has a high acoustic sound with nice heavy bass to balance the sound spectrum she has a maximum what output of 900 watts it is a Pro Amp and uses the same internal parts as the a1800 and a2200 series amplifiers the a1800 has much biger filter capacitors the size of beer cans and can be used for any professional indoor or outdoor event the four speaker outputs on the back can support 4 or even 8 speakers at one time to be played.
The sound performance of these amplifiers are tremendous the internal parts are excellent for long-lasting performance still a 3 speed cooling fan sound be placed on top of the amps venting area to keep the monster cool heat is the enemy of any solid state audio. The VU meters are identical to the a3000i power amp which happens to be the big brother of all the 1800 and 2200 series Cerwin Vega Power Amplifiers the a3000i has a tremendous amount of watts to push any speakers series that is attached to it.
Basically the breakdown of all these vintage Vega power amplifiers are the same each unit according to the model number that you may have purchased carries more wattage than the other
The a600 would be the top of the line in wstts per channel the next would be the a3000i then the 1800 and then the 2200 and on but the sound quality of all these units are basically identical.
You can find these mag nificent power amps showing up on ebay regularly and with a little care they can last a life time.
Parts can be found to update the transistors of all these vintage Cerwin-Vega power amp and my advice to you if you want a reliable and powerful sounding audio invest in maintaining and keeping these wonderful amplifiers alive and you be happy you did 4 generations to come.

david (August 11, 2013): Repair of a Cerwin Vega power amp is cheaper than buying new plus the new digital sound is garbage when compaired to solid state transistors.
