Comparison

How It Compares With the Alternatives

Buying the original brand part

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.

Buying from an auction listing

Condition and provenance are not described, there is no written quotation, and there is nobody to ask a technical question afterwards.

Redesigning the stage around a current device

Sometimes the right long term answer, but it is an engineering project. Replacing the tube is a maintenance task.

Use Guide

Handling and Fitting

  • Keep the item in its packing until the socket and cooling parts are ready
  • Handle by the body, never by the anode terminal or the top cap
  • Inspect pins and contact rings before fitting
  • Observe the specified warm up before applying high voltage

Yes. Send the number exactly as it is printed on the equipment or the tube. 4CX10000J is quoted against that designation, and if we cannot offer it we say so rather than substituting something else without telling you.

Do I have to order more than one 4CX10000J?

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.

What data do you send with the quotation for 4CX10000J?

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.

How is 4CX10000J packed for export?

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.

Can the matching socket be supplied with 4CX10000J?

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.
