Vacuum Tubes
what were the most common types of vacuum tubes used?
in their hay day what were the most commonly used vacuum tubes..ie diodes, triodes, pentodes..
It would most probably be diodes, as there are most circuits use some kind of rectification, while not all circuits use amplification that is what tr/pentodes are mainly used for.

Vacuum pick up and extraction tools in watch making kit
The Bergeon Vacuum Dust Extraction system is the ultimate dust cleaning system which does not need any additional equipment. It can be used to safely remove dust and other tiny particles from the watch dial face, without disturbing anything. It can also be used to clear dust from the interior of watch cases. The work area after working with watches and servicing them can be cleaned spotlessly with this vacuum system. There are literally unlimited uses to which this system can be put. This vacuum station can be used by two persons optionally; in such a case, there are additional items to be purchased to make it possible. This vacuum system has 110 Volt motor, 20 mbar vacuum, one inlet filter, one foot switch, a bottle with special oil for the motor and a stand with a holding device for stylus. It comes with a 3 metre long tubing, which has a diameter of 6mm. This vacuum system includes one vacuum stylus and soft white brush and a coarse blue brush. The same model comes as a 220 volt system too.
The Top Quality Vacuum pick up system is an entry level system that can come in handy in all watch workshops. It is highly efficient in removing dust without scratching or damaging delicate parts like dials. It has ten types of pick up tools. This system has a robust pick up pump and is very quiet. It has hose support and an ergonomic probe handle for easy handling. It includes seven pick up cups and ten pick up tips. It operates at 240 volts. The system is easy to use and reasonably priced.
The Bergeon vacuum pen is a tool that can be used to handle and move items like dials, bracelet parts, index and many more without worry of scratches and marks. The way to operate this pen is very simple: There is a small rectangular button on the “pen” that has to be pushed, the end piece should be set on the item to be moved and the button should be released. Two end pieces, one small and one large are included. The small head and large head replacements are also available from Bergeon.
Bergeon replacement Oil for Compressor Motor is specially made for use with the Ultimate Dust Extraction System motor. The Bergeon Coupling Attachment Piece is an item that is required to couple the accessories together for use in dust extraction system. There is a Bergeon Soft White Brush Attachment and a Coarse Blue Brush Attachment that are designed specially for use with the Bergeon’s Vacuum Dust Extraction System. The Bergeon Precision Hand Blower can be used with a dust extraction system; by pressing a button, the precise nozzle becomes operational and blows away dust from a surface effectively.

Upmarket waterfronts are sterile and boring
“Urban waterfront redevelopment in Metro Vancouver has made our shorelines sterile and boring.” So Bob Ransford begins his May 29 Vancouver Sun column, followed by this left-right to the solar plexus: “This is in contrast to the gritty, bustling and eclectic waterfronts of Metro Vancouver’s past.”
