DSL5C bias


Hi, I've just bought a DSL5C combo that sounds fabulous.

Just to know when I will have to make tubes replacement, can you tell me:

  • - if the 12bh7 power tube needs a bias adjustment when replaced ?
  • - if the ECC83 preamp tubes need to be balanced ones or not ?

Hi Joel,

You would need to replace 12bh7 power tubes in about a year to 18 months, and they would need a bias adjustment. 100mV

The ECC83 will need to be replaced at some point, with no balanced needed.
