We reserve the right to make unannounced technical upgrades!

Protect the poweramp from mechanical knocks (tubes!)

Let the poweramp cool down before you transport it (app.10 minutes).

Tubes need about 20 seconds to warm up after you switch the power on,

and furtheron a few minutes before they reach their full power capability.

Avoid storing the poweramp in damp or dusty rooms, they are hard on jacks, 

switches and potentiometers.

Ensure air can circulate at the rear, the front and both sides of the poweramp 

to allow for adequate cooling (increases component life).

Never operate the poweramp without an adequate load!

Replace tubes with select             replacement tubes (special selection criteria) 

to avoid microfonic properties, undesireable noise and unbalanced 

performance.
