Krell KAV 250a one channel stopped working

I am not the first owner. I purchased this amplifier a long time ago from Audiogon. It sounded great , the typical Krell sound: authoritative tight bass,  huge sound stage and insanely massive power and dynamics. A few weeks ago the left channel stopped working. I thought may be it is the fuse, so I purchased new fuses and replaced the left one, the left channel started working without problems and sounded great. Then, I decided to change the fuse for right channel which was working perfectly but because I am a bit of perfectionist i decided to do it. I took the fuse out, inserted a new one in with difficulty. The fuse cap would not go into the housing and I had to struggle with it. After replacing it the right channel stopped working and never worked again. I decided to move  on and sell the amplifier which is what I was going to do anyway because I am liquidating my system.
Thus I will sell this unit as is at  a discounted price hoping the buyer will have more knowledge and skill with the fuses and can fix it.  You buy at your own risk because I don’t know if this is fixable.
