Tubes Asylum Questions about tubes and gear that glows. FAQ |
|
I had taken bias and other voltages yesterday and today decided to put in a matched set oh EH 7951s in my Fisher X-101-C and the one channels volume output was out and the one tube had a scary huge red glow, it burnt the side of the glass and left a big mark that looks like getter. It was on 15 seconds and the glow was getting worse.I had a real sick feeling and play time was over real quick and I took a nap. Caps are all new and voltages were perfect? Cheap tube? I used two other quads with no problems in the 101c. Original Fisher black bases and RCA's. I used the EH's for 3 hundred hours in a 500c and had no issues until tonight. Guess I'll have to use the variac and plunge in tomorrow. Too much dramaAny opinons appreciated
Thanks
