300BC Fuller is carried in our fuller tubes catalogue as an audio tube of the type used in valve amplifiers, pre-amplifiers and guitar amplifiers. It is supplied against the designation printed on your equipment rather than against a substitute. It is used in valve amplifiers built around classic directly heated triodes, and it can be ordered as one piece for a repair or in repeat quantities for a build programme. HAN Trade (Beijing) Company has supplied electron tubes worldwide since 1993. Every item is tested before shipment and carries a warranty against defects in materials and construction.

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.
Choosing the envelope style for a 2A3 single ended build
Retubing a 845 amplifier that has been in service for years
Supplying a dealer with a spread of audio types on one order
Replacing an output pair in a customer owned amplifier
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.
Current production types can be reordered next year. NOS stock cannot, which matters if you are building amplifiers rather than restoring one.
Fine for a single ended stage or a small signal position. For a push pull output stage, matched tubes are worth asking for.
Works until the type is out of stock. A supplier that carries the line continuously is what a production schedule needs.
Yes. Send the number exactly as it is printed on the equipment or the tube. 300BC Fuller 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.
