Six years later the 400 Series Two was introduced. New, inside and out, it had improved specs, rated at 210 watts per channel and the old-style VU meters were upgraded to dual multi-LED output meters! UIt retailed for a whopping $700, that's over $3,500 today!The 400 Series II, designed by world renowned Audio designer Bob Carver, is a high-powered audio amplifier designed to meet the rugged requirement demanded in professional applications, in which many of these were used for. It boasted a new generation of extremely fast, high energy silicon output transistors, and a host of new materials and techniques only dreamed of a short time ago has made possible an amplifier with performance characteristics that extend virtually beyond the limits of measurability. At 20 cycles per second, damping exceeds one thousand and distortion is so low that it must be measured with only the finest laboratory equipment. Continuous power levels can be delivered into 8 ohms from 20 cycles per second to beyond 20,000 cycles per second.The manual gives this a Power rating of 420 Watts, or 210 W/Ch into 8Ω through full spectrum and both channels fully driven. It has an impressive Total Harmonic Distortion (THD) of less than 0.09%, `below what the human ear can detect! Remember, these are what audiophiles call "Vintage Watts," from an era where, unlike today, it was a sin to manipulate or elaborate the power ratings! The rack-mount PL-400 II takes up 4 spaces in your rack, weighs 35 lbs and measures 10” D x 7” H x 19” W. By "The Best, Ltd." policy this order will be double-boxed for secure shipment. The Free Shipping is for the Lower 48 only, HI & AK must select USPS Priority shipping at checkout! Insurance & Signature are covered on us! Paid items can be picked up in the Denver Metro area at no charge. Condition:This rare, rack-mount amplifier is in "Good" condition with some signs of use and nice, bright VU meters! Aside from a few scuffs to the cabinet, there are several scuffs & scratches to the front panel as seen in the pics. Of course these cosmetic issues don't affect performance, still we are reducing the price so YOU SAVE! All the original knobs are present and complete as is the attached grounded AC cord. The manual has gone missing, but no worries, it's available online or we will send you the PDF file directly on request. We are also including the pre-owned, high-quality Atlona RCA Audio Cable so you are ready to go! Please inspect the pictures thoroughly for actual condition.Service:On inspection, this unit was not working, so as with all vintage amps it went to our tech for service. This amp had been previously serviced and had a mixture of different power transistors installed, several that were shorted. Our tech knows having balanced transistors are important, so he decided to replace all of the driver and output transistors. Luckily we has plenty of the 2SD555 output transistors in stock, while the drivers were upgraded to brand new MJ21194G's, all with new silicone insulators and of course, new heatsink compound. Before it was powered back up, the preamp circuitry was evaluated and several parts were replaced, along with all the electrolytic caps! A total of 4 electrolytic capacitors and 16 transistors were upgraded to brand new, high quality parts from Onsemi, Nichicon, Rubycon, etc., never any used components! All vintage amps receive the following services and much more, all performed by our qualified technician:Lid is removed & unit is inspected to determine if any attempted amateur repairs exist that need to be corrected, or substandard parts that need replacementThe exterior, all knobs & plexis are cleaned & detailedWhile the front panel is removed for cleaning, all attachments are re-glued and dried out foam inserts replaced.All switches & pots are cleaned internally with Specialist Contact Cleaner (proven superior to DeoxIT by our customers), while those with special needs receive the less aggressive DeoxIT F-5All lamps that are out, or believed to be prone to failure, are replaced if necessary. LEDs are used whenever compatibleAny faulty components, or those with known issues, such as jacks, fuse-holders, feet, etc., are replacedAll PC boards are inspected; all questionable solder joints are re-flowedAll electrolytic caps are inspected for bulging or leakage, those that are at risk or have known issues are checked with the Huntron Tracker (allows evaluation while in-circuit so component does not need to be removed). All questionable caps are replaced with brand new parts, not NOS!DC offset is adjusted & channel levels are calibrated & balancedFront panel is cleaned & detailed before reassemblyCabinet is cleaned & detailed, any wood is polished with Old EnglishTesting:We set this up on our test bench and it passed with flying colors! It powered right up, pumping out a clear, distortion-free audio from both channels with no hum or buzz! All inputs and outputs have been confirmed working and the controls work smoothly with minimal noise. Further testing was performed, if there is a specific feature you would like to know more about just let us know before buying.

Typically, our title will give the "Total" watts, while the description will give more detailed information. We suggest you do independent research to be assured you are making informed comparisons when shopping.Internet State Sales Tax: In June 2018, The Supreme Court mandated that all States may charge & collect State Sales Tax on all internet purchases shipped into their state.
