Hi guys,
searching around the web I found these words on the Eurotubes web site:
"KT88's in a Dual Rectifier??
Yes! KT88's in a DR... This is one way to make a DR into "Frankin Rectifier" The bias on the DR's is set very cool for 6L6's and EL34's but the average KT88 draws about double the natural plate current of the average 6L6 so when you run KT88's in a DR with the amp in the EL34 rectifier mode the bias comes up to where it should be and the bottom end gets VERY deep and strong along with a punch that is truly enormous!
May the amplifier Gods have mercy on your speakers!! "
So I bought a good quartet of KT88 Tubes and I just tried them in my DR, with these settings:
Spongy mod - Vacuum tube rectifier - el34 bias setting.
Well my DR sounded MASSIVE, but it started to do a bad smell..
Obviously I turned it down and now I'm waiting for the amp to cold down too.
Here's the question: is the el34 bias setting too much for the KT88s?
Or that smell comes only from the fact that the tubes are new?
Thanks a lot
