█ How to replace tubes

The procedure to replace either the small signal tubes or the power tubes is roughly the

same. The small signal tubes do not require biasing. The power tube's individual bias

settings are fully automated thanks to rockSteady bias.

!WARNING! N ever turn the amp on when the top cover is removed. The voltages used

inside the Detti are lethal!

Procedure

1) Turn off the poweramp.

2) Unplug the power cord.

3) Let the tubes cool down and the power supply drain any residual voltage for about 20

minutes

4) Remove the top cover.

5) Carefully and slowly remove the tube you want to replace by gently pulling and ever so

slightly wiggling it. Easy does it.

* in case of a power tube, carefully lift the metal retainer and put it alongside the tube

6) Press the new tube into the socket. It can only go in one way. Don't force anything!

7) Replace the top cover and tighten screws.

8) Turn on the amp and let it adjust itself to the new tubes for about 10 minutes.

9) Rock on.
