5150 Iconic

I emailed EVH/Fender & here is the answer I got about biasing the Iconic:

"Thank you for contacting us. These amps do have an internal bias adjustment and the bias will need to be set when new power tubes are installed. Unfortunately, we are not able to advise about bias voltage specs due to liability reasons. An Authorized Service Center would be able to set the bias to the factory spec. You can find a location in the link below".

I'll check bias soon see where it is now. Get plate voltage and bias for 6L6GC's. The reason I learned to bias is so I didn't have to depend on a tech or someone else to do it. Been biasing for years. Kinda knew they weren't going to tell me bias specs. Marshall does.
