Only a certified technician should bias Carvin amps, this is very
dangerous, you can get hurt, please be very careful when working
with any tube amp!
If you have changed the tubes make sure they are a matched set. When you bias the
amp at 75mA and the tubes are matched you will have the desirable 20mA going
through each of the 4 Power tubes.
- The Bias for the Belair212, Nomad should be 75mA at 120VAC.
STEP 1
These are the tools you will need:
1. A flat head screw driver
“small”.
2. A multi-meter, w/ milli amp
reading.
3. Banana to clip leads.
4. Amp stand (optional).
STEP 2
Take the amp out of the amp
enclosure (cabinet). Set it in an amp
stand. Be very careful with the tubes
they can break.
NOTE: If you don't have an amp
stand then support the chassis on
some blocks of wood so that the
power tubes are not touching
anything - they get very hot!
