If you are looking for one of these little monsters, this is the one you want. It was sent to Krell in June of 23, and has had all capacitors replaced. It has been cleaned, tested and verified as meeting original specifications. There was a recall on some of these for a potential overheating problem. That recall has also been done. This unit is as close as you can come to new. Beautiful cosmetic condition and now ready for another 12 to 15 years of trouble-free service. Don’t be fooled by the others listed. Their capacitors are long past designed service life, and need to be replaced. I have done the upgrades and paid the freight. This amp has plenty of power, and is very detailed. You will not be disappointed with this one. This amp is adult owned and has been meticulously maintained. There is a small mark on the case from shipping, but otherwise, is pristine. Sorry, the original owner did not retain the original packing material when I purchased it. This is a very powerful amplifier, rated @ 250 watts/channel into 8 ohms; 500 watts/channel into 4 ohms in stereo mode, and 1000 watts into 8 ohms bridged mono mode. It is a dual mono design, fully complimentary and balanced from input to output. The input/driver stage is class A. The output stage is class AB using proprietary output devices created by Motorola exclusively for Krell.

An extraordinary example of the mighty Krell KAV-250a two channel power amp. This unit is fresh from a full spa treatment at Krell Industries, Orange, CT in June of 2023. Krell factory technicians thoroughly tested and inspected this unit. All recommended service was performed including thermal and fuse updates for an overheating recall. The unit is verified as meeting original factory specs. A detailed invoice of work performed is included in this listing. The amp has less than one hour of use since its return to ensure proper operation, and has not yet been put back into service. For all intents and purposes, it’s new. It drives my 4ohm speakers with authority and clarity that must be heard. There is not a finer example anywhere. This amp is adult owned and has been meticulously maintained.

Krell KAV-250A Stereo Power Amplifier 2 channel 250/500 8/4 Ohms Great Condition Technical highlights The KSA-250 is, without a doubt, the most visually appealing amplifier that Krell has yet marketed. Though large and very heavy, the presentation is one of stoic grace rather than imposing high-tech visual intrusion. The amplifier body is finished in flat black, with heatsinks externally lining both sides from front to back. The rear panel is neatly laid out, with single-ended phono sockets and balanced female XLR connectors on either side. Additionally, there are two sets of five-way binding posts for loudspeaker cable connections, which makes speaker bi-wiring a breeze. The front panel is finished in an elegant brushed-gray finish with large, black, attractive, downward-facing handles. The feather-touch power switch is located in the center of the front panel, just above the ubiquitous Krell logo. A blue LED power tally light is positioned just above the switch. All in all, a very nicely designed package. Internally, the KSA-250 is a study in simplicity as well as a technological tour de force. The 4.5kVA transformer, which by itself weighs 85 pounds (!), is located just behind the front panel, and is in turn followed by four 47,000µF capacitors covered by a printed circuit board. It is important to note that there is no wiring in the signal path, all connections being made via the pcb in the front end, and gold-plated copper-beryllium busbars in the output stage. There are 24 output devices per channel, all operating in class-A mode down to 3 ohms, where the amplifier reverts to class-AB (see Sidebar 3). The KSA-250 utilizes class-A circuitry throughout the audio and power-supply regulation stages, and can actually generate 320Wpc into 8 ohms. It is DC-coupled throughout, without any capacitors in the signal path, and is a fully modular design employing gas-tight pressure connections between all subassemblies, allowing quick and easy servicing in the field.
