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.
Building a 300B single ended amplifier in small production runs
Retubing a KT88 or EL34 push pull amplifier in a repair shop
Replacing the 12AX7 stage in a guitar amplifier
Holding audio tube stock for a dealer network
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. Shuguang 2A3Z-300BZ 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.
