Darkvoice DV336i owners manual?

Hello everybody

I need a owners manual for a Darkvoice DV336i. Can anybody help me or is there a dv website I can go to?

One more thing, I just put a new Tung-sol 6sn7gtb in the dv336i and the left channel started humming. I put a Sylvania in and the humming stopped. Does this mean I got a bad brand new Tung-sol?

Thanks for your time!

Tubes sometimes hum in the DV 336i. In general, if the hum is ever going to go away, it will after you burn the tube in for a while. Is the tube New Production or NOS?

The 336 line needs modifying to prevent humming when it used with certain tube. I believe it has to due something with the nature of the AC current being used to heat the heaters.

I haven't found a tube yet where the humming didn't go away after a period of burn-in.

Ranging from 5 minutes to 36 hours.

Thanks to all that responded, I have bunches of tubes and this is the first one that has hummed.

I still need a owners manual for the Darkvoice DV336i.

Thanks
David
