After assembling the new tube it would be necessary to adjust the plate current.

Run the Alpin 100 without cover and connect to a transceiver.

Setup of Poti R44

Without power from the transceiver in TX mode; adjust with R44 a plate
current ( as shown in display from Alpin ) to 50mA.

Setup of Poti R45

Slowly increase the power of the transceiver until the plate current jumps in the
range of 200mA, then adjust with R45 the current to 180mA.
