component problems driving me from the hobby?

I have had a very bad time of it for the last,almost two years,with varying little problems.Alot of new additions,that just continue to plague me with component failure.From amp to line conditioner/table/CD player,tonearm etc.It is almost surreal!

I have been at this for about fourty years,so I know what I'm doing,but this latest round may drive me from the hobby!Btw,I don't feel sorry for myself,but am disgusted!!
I am doing far too much diagnostics/schlepping,and way too little listening pleasure!!I've also spent alot of money lately,on the hobby.

Here's my question,and I really would appreciate some "thoughtful comments".....

My pre was in use playing my CD player and I noticed noise in the volume control when I moved it.This happened awhile ago,so I just blew some air into the contacts and circuitry with an air spray can.It cleared up,awhile ago,and somewhat tonight.

Yet,upon further play I still noticed some noise(like a static/dusty sound,when moving the volume control.I stopped CD play and ran a few click stops to hear it's effect....After five volume click stops(only around 9 or 10 o'clock on volume control,I got a POP sound,and the pre went dead!

I can't check out my analog,because I am awaiting a new arm,which had set up problems.

Thinking I am cursed,as of late,as I have a dedicated room/dedicated lines/superb line regeneration/line conditioners etc.

Any thoughts as to the cause of the pre failure?

Thanks so much...
