I understand the emotion of the OP, but when calms down, I would suggest:
1) Go solid state-no tubes to break, bias, etc.
2) If Physical Media is getting to be to much, move it to a server
3) Investigate Streaming Services-with Quobuz, now there will be at least two High Rez services to choose from.
Remember that you got into this hobby because you love Music and love hearing it reproduced faithfully. There are lots of ways to do this on a retiree income and with less stress.
And yes, we have all made stupid, expensive mistakes. No one does this on purpose—they are called accidents for a reason. Don’t be so hard on yourself
