Hello Team, 

On the manual of the DSL1hr Vietnam its says that speaker is allowed only 16ohms.

But on the DSL1H (50th Anniv) it is mentioned it can be both 8 and 16 ohms.

Not sure if the Vietnam version can use the 8ohms as well? and it was not published on the amp or manual?

Please advise

Thanks alot

Mike

Hi - 

  I wanted to change the power tube in my DSL1HR Head.  Will it need Re Biasing ? or I can go ahead and just swap the tube and no problems it is good to go. 

Thank You
