Hi Guys, I need some trouble shooting advice.
I had a power tube short out, and a fuse blew on my MKV. I bought 4 new 6l6s, a new fuse(4A SB), installed all, hit the bias switch to 6l6. Fired it up and it sounded great for about 45 mins, then I heard a low hum, then the fuse blew again and she powered down.
Any thoughts on what I should look into? Rectifier tube?
It is #191, so it is pretty old. Do you think it is ready for a normal checkup at a tech anyway after 8 years?
