FD912S belongs to the vacuum tubes line.
FD912S belongs to the vacuum tubes line. It is an industrial transmitting tube of the type used in high frequency heating, welding and RF power equipment, and it is quoted for single repairs as readily as for repeat production quantities. It is used in broadcast transmitters industrial RF generators and research equipment, and it can be ordered as one piece for a repair or in repeat quantities for a build programme. Since 1993 this has been our single trade. Items are tested before they leave and are packed for the destination and the transport method chosen.

Electrical ratings are supplied from the data we hold for the type when we quote, rather than being published here, so that what you check against your circuit is the data for the item actually being offered.
Replacing the final stage tube in a shortwave or FM broadcast transmitter
Keeping a high frequency welding or annealing line running through a shift pattern
Rebuilding an RF amplifier for a laboratory or accelerator installation
Building a spares package before a tube reaches the end of its service life
You send the type exactly as printed on the equipment.
Price, availability and the data we hold, by email.
Socket, cap connector or cooling parts added to the same offer.
Extensively tested prior to shipment, with a warranty against defects in materials and construction.
Packing and transport method chosen for the goods and the destination.
Where the original is still produced it remains an option. Where it is not, an equivalent quoted against the same designation is what keeps the equipment working.
Condition and provenance are not described, there is no written quotation, and there is nobody to ask a technical question afterwards.
Sometimes the right long term answer, but it is an engineering project. Replacing the tube is a maintenance task.
Power grid tubes sockets and tank circuit components for AM FM shortwave and TV transmitter stages.
Oscillator tubes thyratrons and high voltage capacitors for induction hardening dielectric heating and high fr
RF amplifier tubes vacuum capacitors and switching tubes for accelerator groups plasma laboratories and univer
Yes. Send the number exactly as it is printed on the equipment or the tube. FD912S is quoted against that designation, and if we cannot offer it we say so rather than substituting something else without telling you.
No. A single piece for a repair is a normal order, and the same item can be scheduled in repeat quantities for a production or maintenance programme.
The data we hold for the type goes out with the price and the availability, so the item can be checked against your circuit before you commit to the order.
It is packed so that the fragile surfaces are held clear of the carton, and the outer packing and transport method are chosen for the destination and how urgently you need it.
Yes. Tell us the tube type and the socket for that base layout is quoted on the same offer, so both arrive on one shipment.
Send the designation and the quantity. Price, availability and the data we hold for the type come back by email, and the socket or cooling parts can go on the same offer.
