4. Old Tube Removal.

===========================

Prior to continue you must be absolutely sure that there are no residual voltages

in the amplifier - see (2) and (3) above!

Be careful - the tube may be VERY HOT!

First unthread the temperature sensor (which looks like a small transistor), out

of the rubber chimney. Push gently the chimney towards the tube center while

taking care not to bend the three leads of the sensor and fully unthread it.

Now unscrew both M3 screws that hold the anode clip to the UHF suppressor (look at

the two red arrows in the picture below). Save the two screws and washers.
