Nice Krell showcase 5
5x 125W 8ohm, 5x 250W 4ohms
(very same as S1500 with a different face plate)
In perfect working order full recap done (using heavy duty parts and mostly 105 degree Celsius caps)
-100+ capacitors replaced, not just the main power supply one like most shop do...
-power supply section went from a respectable 80,000uF to an even better 120,000uF (50% improvement)
-preamp section bypass cap changed from 33uf to 82uf (250% improvement)
-amp section caps replaced from 33uf to 220uf (660% improvement)
-feedback capacitor changed from generic polarized electrolytic to nichicon muse non-polar (the green one on pics)
-input capacitor removed for direct connection. (Krell product having coupling caps input still bug me, what a sonic bottleneck!)
-power supply mods to remove heat stress issue and improve long term reliability. From official Krell service bulletin: fully approved. (In stock form, driver board run 24/7 causing much of issue associated with the amp long term reliability) After mod, amp draw ~10watts from wall when plugged in and proper;y shut down all of the circuitry. (versus ~75watts)
I have original box.
No power cord but I could throw a generic one if you absolutely need one.
