same exact rating:

B90: 3.0 amp for 115 volt operation; 1.6 amp for 230 volt operation
B120: ?? amp for 115 volt operation; ?? amp for 230 volt operation
2. AC Power Cord - Use this permanently attached grounded AC power cord to connect
your B Series amplifier to mains power. This cord comes supplied with the appropriate
plug for your geographic area. CAUTION: Do not use an adapter to defeat the third
grounding pin on this plug or severe electric shock may result!
3. Preamp Out (Effects Loop Send)
- Use this 1/4" unbalanced jack to send signal to a
professional outboard effects processor.* Output level is approximately 0 dB to +4 dB and
is post-EQ and post-Shape but unaffected by the setting of the Volume control. The
signal from this output is the same as that from the Line Out on the front panel (see #7 on
page 4).
4. Amp In (Effects Loop Return)- Use this 1/4" unbalanced jack to return signal from a
professional outboard effects processor.*
* In-line effects (such as footpedals) intended for low signal levels should be placed
between your bass and the front panel B Series amplifier Input and not connected with the
rear panel Effects Loop jacks.
