Handling and Care
Protect the amp from mechanical knocks (tubes!).
Let the amp cool down before you transport it (approx. 10 minutes).
Tubes need about 20 seconds to warm up after you switch the power on,
and further few minutes before they reach their full power capability.
Avoid storing the amp in damp or dusty rooms, they are hard on jacks,
switches and potentiometers.
Make sure air can circulate at the front and top of the amp
to allow for adequate cooling (increases component life).
Never operate the amp without an adequate load.
Replace tubes with select
to avoid microphonic properties, undesireable noise and unbalanced performance.
Attention! Please read the following!
This guitar amplifier can produce high volume levels.
Exposure to high volume levels may cause hearing damage!
Leave tube replacement and power amp biasing to qualified professionals.
Be sure the unit is switched off and unplugged!
Caution! Tubes can get very hot and burn skin when touched.
Always use high quality cables.
Never plug the amp into an ungrounded outlet!
Never bridge a defective fuse and be sure replacement fuses feature
identical ratings!
Pull the AC mains plug before replacing fuses!
Never open the chassis or attempt repairs on your own. Consult qualified
service personnel!
Never expose the amplifier to extreme humidity or dampness!
Please read the instructions carefully before operating the unit!
Be sure to operate and handle this amp as it was designed for. To this end,
please heed the instructions in the operator's manual.
You'll find an additional pamphlet accompanying this owner's

or injury of persons". Be sure to read it before you plug
the preamp in and switch it on!
