Need to know the bias on Golden Tube SE-40

Off the top of my head, recommended bias is 535 to 540. It's a pain to get them all right, though. I'll try to verify the bias numbers later this weekend. I always had luck with the 5881's. Sounded very nice with an Audio Research LS3 preamp. It had more detail than my McCormack dna 0.5.

Hey Neil,The bias voltaage is 635-640mV..To get some extra air and soundstage try using some NOS Sylvania or Tung-Sol for your 6SN7's..I always liked the stock 5881 Sovteks for power.. Good Luck
