[Elecraft] VFO problem

[Ross Primrose]

My grandfather (Ex K4GF, SK) was a TV repairman during the tube TV era.  
The most common fault requiring a house call was the housewife not 
plugging the TV back in after she unplugged it to vacuum....

For intermittent problems one waited until the owner left the room then lifted up one side about 6 inches and let it drop.  Usually either fixed the problem or caused a hard fault that could be troubleshot.  Now the owner just buys a new TV.
