Just returned from Krell all new Caps replaced in both amplifiers and I have the invoice for $2500, direct from the factory. Still wrapped in original packaging and boxes never removed since I had them upgraded. This is your opportunity to purchase a set of Krell 250FPB monoblock  amplifiers that are like brand new.

 250-FPB (Full Power Balanced) Amplifiers. Nevertheless, Krell founder Dan D'Agostino was adamant: Krell's Class A components were designed for music playback.
The output stage in all FPB amps is fully and actively regulated through a "free-floating feedback arrangement" where "ultra-fast regulators" operate independently of the output stage while monitoring its condition and responding to even the smallest drop in current or voltage with "essentially instantaneous regulator response."The claimed result is class-A performance with less heat and power consumption than other more conventional designs. Around back in a vertical array, just next to a carrying handle, are two pair of speaker binding posts. These are great connectors and make child's play of lashing up all manner of recalcitrant mind-of-their-own cables. Between the upper and lower set you'll find a balanced XLR input next to the CAST connector. Over to the right are a pair of Krell Link connections (Krell Link allows remote operation of the amps), with a heavy-gauge captive power cord below.

When powering up from Standby, the amps default to the CAST input if this is connected, even if you've got an XLR cable plugged in. There is no single-ended input, although adapters are available from Krell. They just don't believe in 'em.

"CAST has another important aspect. It really doesn't matter how long the connecting cable is because the cable's reactive effects are still never going to be more than a negligible part of the total circuit impedance. This means that preamplifiers and power amplifiers can be placed where needed, unconstrained by cabling problems."

 The Krell amps excelled at retrieving the pace and timing, the very nature of the music.

The bottom end was powerful, just what you'd expect from Krell. It was impressive,  In fact, I couldn't help being aware of how great the bass, I  enjoyed it.

Questions for the seller
I noticed that the pictures are all of one of the amps, which is "right finned". Is the other amp "left finned"?
I have a left fin and a right fin. The photograph was taken before the amplifiers was shipped to the manufacturer for inspection and for a new caps. When the amplifiers returned I did not remove them from the factory packed boxes to take additional photographs. To answer your question yes, one left and one right
