Product Overview

About KT88G Fuller

KT88G 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. Equipment using this type is generally found in valve amplifiers built around classic directly heated triodes. Ask for one piece or for a scheduled quantity. We have specialised in electron tubes since 1993. Each product is extensively tested prior to shipment and carries a strict warranty against defects in materials and construction.

Comparison

How It Compares With the Alternatives

Current production versus NOS

Current production types can be reordered next year. NOS stock cannot, which matters if you are building amplifiers rather than restoring one.

Buying unmatched singles

Fine for a single ended stage or a small signal position. For a push pull output stage, matched tubes are worth asking for.

Buying through general distribution

Works until the type is out of stock. A supplier that carries the line continuously is what a production schedule needs.

Use Guide

Handling and Fitting

  • Let the amplifier reach normal operating temperature before judging a new tube
  • Fit output tubes as a set where the stage is push pull
  • Check bias after fitting where the amplifier provides an adjustment
  • Keep the original boxes so spares can be stored and identified later

FAQ

KT88G Fuller Questions

Can you quote KT88G Fuller against my nameplate designation?

Yes. Send the number exactly as it is printed on the equipment or the tube. KT88G Fuller 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 KT88G Fuller?

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 KT88G Fuller?

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 KT88G Fuller 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 KT88G Fuller?

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.
