Hey all, I'm thinking it's time to change my tubes. My tone has been sucking, I've been getting squeals, and it's been around 5 years since. It's a Fender Hot Rod Deluxe. I was wondering if you could give me some pointers on how to go about changing tubes, or whether it's better to just throw it at a tech. I know nothing about changing tubes, which tubes to get, which tubes will sound good for my amp, whether to change preamp or power or all tubes. If you could help me out by giving me some suggestions, that would be great! Also, the amp I am playing is a Hot Rod Deluxe, limited lacquered tweed with Jensen speaker, produced around early 2000s? Does anyone know how limited run these were? I read somewhere it was 250, but I am not sure. I paid around $1,100 CAN then, and now looking at what HRDx are going for (around $600 new?), I can't help but feel a bit ripped off. What do you think? So yeah, two questions: 1) how to change tubes; 2) value of my amp Thanks!
