is an old friend whose time it has come to say goodbye. I am the third owner of this legendary Krell KSA-50 Mark II Class A power amplifier. This amplifier is widely cloned by audio hobbyists for a very good reason: it is simply one of the best sounding audio amplifiers ever designed. Krell spares no expense with materials, components, or engineering.

Finding a KSA-50 MKII for sale or auction is a rare event. If you are handy with electronics (or know someone who is), you can put this unit back in service with very little effort. T is actually very little to be done. This amplifier lost the cooling fan in October, and I have been debating what to do with it ever since. I have recently moved on to an integrated theater system and have decided to let her go.

The second owner bypassed the fan's current limiting resistor in order to increase the air flow to the Class A output cluster. That was a good idea considering his semi-enclosed mounting arrangement. At the time of the modification in 1999, he installed a new fan and all new power supply filter capacitors at considerable expense. are all the issues with this unit:

1. This needs a new cooling device (original Pabst fan from Krell is priced at $250. I am certain that an equivalent cooling device can be sourced for much less).

2. It will need a new fuse holder for the mains.

3. It will need a new fan speed limiting resistor if you chose to return the unit to original fan speed.

4. The cover screws have all been replaced with stainless steel versions. Bronze is pretty, stainless makes more sense.

5. T are dings and scratches on the cover/case/rear handles. T are plenty of photos included that show them, so no surprises. It is not museum quality. I really wanted to save this for a full restoration, I just do not have the time.

The chassis is exceptionally clean, having lived in a dust and smoke free environment all its life. This amplifier performed beautifully until the fan failure, and with the relatively new filter caps, I believe that t are many more years of enjoyment left.

This is a great opportunity to own one of the most sought after Krell Class A amplifiers for very reasonable price.

I will consider every reasonable offer for this amplifier.

Shipping will be in a custom box lined on every surface with custom fitted 1-1/2" rigid styrofoam, the amplifier will be cellophane & high density bubble wrapped to protect against humidity. I will be adding a small $10 to the auction to cover brand new foam & 3/16" wrap.

Every care will be taken to make sure it arrives safely, no matter w the destination. I will ship this anyw in the world UPS delivers. I have shipped worldwide with 100% success. Local pickup would be preferred, for obvious reasons.

Please E-Mail me with any questions; I will be happy to answer all.

Thanks very much for looking, and good luck!
