b) TUBE REPLACEMENT GUIDE
It is not uncommon for tubes to malfunction during shipping. If your amp is not working properly
first check all connections and settings, and refer to the following tube replacement guide.
1) The 12AX7A preamp tubes are the smaller of the 2 types, and are located in the following order on
50w models: V1, V2, V3, V4. On 16w models these are V1 and V2.
To start with, V1 is located closest to the input jack. It is recommended to turn your amp upside
down to replace tubes. All tubes are keyed in the same direction.
Replacing V1 (and/or V2 on 50w models) may help reduce feedback due to microphonics.
If the power amp is not functioning, check or replace the power amp driver (16w models = V2,
50w models = V4) Check V4 by inserting a signal into the Effects RETURN jack. If the power amp
still does not work, replace the EL84 power tubes.
2) The EL84 power tubes are located in the following order on 50w models: V5, V6, V7, V8.
On 16w models, these are V3 and V4. Normally you’ll want to replace these tubes as a set.
Sometimes you can spot defective power tubes when they are glowing red-hot along with an
audible hum in the speaker when the amp is idling. If this happens, shut the amp down immediately.
After the tubes have cooled down, carefully pull straight out to remove. It is recommended to
turn your amp upside down to replace tubes. All tubes are keyed in the same direction. Running
defective power tubes could damage the amp. It is recommended that you have a spare set of
EL84 power tubes along with several 12AX7A preamp tubes.
