[Hallicrafters] Very slow warm-up for SX-62

[Carl]

Unplug the radio and do a full recap as well as checking for out of 
tolerance resistors. Otherwise you risk burning up the power and audio 
transformers.

This is the hardest, along with the similar SX-42, Hallicrafters to work on. 
Its not for a first timer.
