Report Review for product Vacuum Tube - 5AR4 / GZ34, JJ Electronics

I had put in completely new J&J tubes. Come to find out, the J&J rectifier Tube was constantly burning out my fuse. I found this out when I took my Orange amp into a, recommended by orange, amp repair site, technicians. They stated J&J isn't the best tubes for this amp. "Orange TC AD30 combo".
Also to be clear I brought the amp in for other maintenance issues and repairs after I replaced the tubes with a complete set of J&J Tubes. The Rectifier was noted after all other repairs were completed and the Rectifier tube was determined to be blowing out the fuses. He replaced it with a Sovtec tube
