HAN Trade supplies China made electron tubes and vacuum tubes: power grid triodes and tetrodes, thyratrons, magnetrons, tube sockets and accessories, vacuum capacitors and high voltage ceramic capacitors.
Equipment outlives the tube types it was designed around. We quote against the designation on the equipment nameplate so an obsolete type does not become an obsolete machine.
Broadcast engineers, industrial RF and induction heating plant, research laboratories, defence and medical equipment support teams, and Hi-Fi and guitar amplifier builders.
Power triodes and tetrodes for broadcast transmitters, industrial RF generators and research equipment, supplied against the type designation already
58 typesShuguang marked audio tubes including 300B 2A3 845 KT88 EL34 and the 12AX7 small signal family, for valve amplifier builders and repair workshops.
54 typesToshiba marked transmitting and industrial tube types including the 7T 8T 9T and E30 series, listed for equipment built around Toshiba designations.
44 typesCeramic and metal tube sockets, cap sockets, chimneys and fixing hardware matched to the base layout of the tube they serve.
30 typesCCG series high voltage ceramic capacitors, water cooled and air cooled, for induction heating plant, RF generators and transmitter tank circuits.
30 typesGas filled switching tubes for pulse modulators, resistance welding controls and industrial switching gear, cross referenced between Chinese Russian a
27 typesNew old stock tubes from Telefunken RCA GE Raytheon and Chinese and Russian production, listed individually because stock of each type is limited.
20 typesFull Music branded audio tubes including 300B 2A3 274B PX4 and 12AX7 types for valve amplifier builders who want a premium envelope.
17 typesFuller branded audio tubes covering 2A3 300B 845 EL34 and KT88 types in several envelope styles for amplifier builders and dealers.
8 typesMagnetron oscillator tubes for radar, industrial microwave heating and microwave power equipment, supplied against the original type designation.
5 typesFixed and variable vacuum capacitors for RF matching networks and high power tuning circuits, quoted against the CKT series designation you specify.
2 typesCooling jackets for water cooled tube anodes in industrial RF equipment, supplied to suit the tube type they are ordered against.
Every listing carries the photograph and the designation used on the original catalogue. If the number on your equipment is not shown, send it by email and we will tell you what we can offer against it.
























A transmitter, a hardening generator or a welding control can run for decades. The tube inside it cannot. When the original maker leaves the market, the machine is only obsolete if nobody will quote the type any more.

Both. A single tube for a repair is a normal order for us, and the same type can be scheduled in repeat quantities for a production or maintenance programme.
That is where most of our enquiries start. Send the designation exactly as it is printed on the equipment and we will tell you what we can offer against it.
By email. Send the type designations and the quantities and we reply with price availability and the data we hold for each type.
Yes. Sockets cap connectors chimneys and water jackets are in the same catalogue and go on one order and one shipment.
Packing is chosen for the goods, the destination and the transport method, and the shipping method is chosen with you according to how urgently you need the items.
