Single Tube 7289 Linear Amplifier. Click on each thumb nail image for a larger view of each component, then use your "BACK BUTTON" to return to normal thumb nail view of this page. These Cavities are machined and milled from NEW virgin stock material, NO reused materials at all. If you are interested in one of these single tube cavities completely assembled & tested please get in touch with me. This is still a Hobby, Perhaps we can even talk a TRADE, hi. Cost + Shipping $245.00USD. Below (at bottom of this page), are schematics of the bias supplies I have used for many years and has with stood many internal flashovers within a tube without a single component failure. One version uses current ( Ik ), limiting that is completely adjustable. This current limiting version is especially useful if this amplifier is used as a driver and MAX. power is not a requirement.
