Let's take a quick look this time at a lovely Krell KAV-280p preamplifier I recently repaired. This one needed a power supply repair and I overhauled the entire power supply module for good measure.

I like your terminology of a dead capacitor...........Cactus.

@rickysnit2163

I have one of these and mine started to switch off, same PS cap issue. Instead of more SMD, I soldered on through hole Nichicons to the SMD pads, bending and cutting the legs short like smd only higher.. 4 10uF 35v and 2 100uF 16v. Did the trick. I took the added step of bypassing the existing larger caps with Kemet MKP at the bottom which gave me an even further boost in sound.

My 280P is always on, the 2250 goes on standby when not in use…

Brilliant video. I really enjoy your careful work, and the way you carefully narrate your work. Before I started watching your channel, I had real plans of buying some say older Levinson or Krell gear, but after watching instructional videos like yours, I will absolutely not even touch it unless the seller can provide hard proof that the unit has been re-capped. Keep up the good work!

Love your videos. Great work as always. Wish you were across the ditch in NZ to fix some of our gear.

I had a krell amplifier before but it was a bit bright for my ears, the top end used to irritate me, had to sell it.

I also enjoy your videos, but would you please allow subtitles as the volume of your videos is low, and would aid with understanding your accent. Cheers!
