Krell KSA-250

A monster of an amp - drives anything

Krell KSA-250 power amp. Massive power reserves and control.

Why am I selling so cheap? I've owned this amp for 16 years. I've never had to have it serviced. It plays but at this age it's due for a recap. It's only a matter of time before it needs service. That could be 2 years or it could be a month - there's no way to tell. But I would hate to have someone buy this and feel like they got ripped off, and I feel like I've got my money's worth over the last 16 years. 

Currently there is a very slight hum in the right channel (only if I put my head right up to the speaker). Something like that won't get better with time. Also, every once in a while (perhaps once in 20 attempts) the start-up relay circuit won't complete the turn-on process. On this amp, because of the massive power draw, there is a relay that kicks in once the amp knows the power is coming in properly. I don't know if I just occasionally have a sag in my power or if the relay is getting flaky but as I say, occasionally the amp tries to start and then shuts itself down. After waiting a few moments I try again and it always starts after one to three attempts. Once on, the amp stays on. I believe this relay circuit is on a separate board and can be relatively easily swapped out. I've read that others have had this problem and it was a simple fix.

The sound from this amp is glorious. I've been using it with Martin-Logan Prodigies, which it has no trouble driving. I use the balanced XLR inputs, which I recommend. If you've read this far, you're probably aware of what a fabulous amp this is. It used to be an A-rated recommended amp on Stereophile when it was still in production. This amp was still built at the time when Krell built everything in the USA and made it bullet proof. The fact that I've run this amp for 16 years without it failing is a testament to the build quality.

Externally, the amp is in excellent condition. There are no dents or significant scratches. The front is pristine. See the photos. I have the original double boxes and the original manual (also available from the krellonline site). I'll give preference to someone who can pick up when considering offers. Shipping this 150 lb package is a pain. 

Don't ask me what sending this to Krell and recapping costs - I don't know. Probably between $1,000 and $1,500, hence my pricing. You'd still have a  good deal. If you have electronic skills and take this on yourself, you can get yourself a phenomenal deal here. 

Please feel free to ask any questions, but I really can't think of anything else to say.
