ADA mp1 - Solid States works only

(1/7) > >>

gg85:
Hi, I'm new here from Italy, this is my fisrt post here.
I've bought few weeks ago an used ADA mp1 Classic in a local shop. I've tried and worked perfectly.
From yesterday I have an issue:
When I turn on the ADA on the display appears the following message: "Tubes are not ready".
After few seconds it disappears and turn to the last used program.
If I use the voicing on solid state everythings it's ok, but, when I change to "Cln", "brn" or "dist" (or I use a program whit that kind of voicing),I can't ear anything. I tried to turn off and on again but anything has changed. One time only it started to sound again on "dist" but after few second of playing the volume started to decay and I can't ear nothing again. Everyone have any advices?

Thank You in advance

Giulio

Hey Giulio, welcome to the depot  :wave: .  Sounds like issues with the tubes ? or tube circuit.  MarshallJMP will probably ask you some questions and help sort it out  :thumb-up: . 

@Dante, did you have similar issues with your classic?

Harley Hexxe:
Hello Giulio, and welcome here :wave:

Definitely, you need fresh tubes in the MP-1 Classic.

Tubes would be my first guess too, easy to replace, if it still not works let us know.
