Description
Quality Transformer QTE 5564 Klystron Transformer Varian MED 01005165 Rev E
The Quality Transformer and Electronics (QTE) Model 5564 is a chassis-mount klystron power transformer built to Varian M.E.D. specifications under OEM part number 01005165, Revision E. Date code 91-27 places manufacture in the 27th week of 1991. Klystron transformers like this one supply the high-voltage and heater power required to drive klystron vacuum tubes, which are high-power microwave amplifiers used in particle accelerators, radar transmitters, satellite ground stations, and industrial microwave systems.

Applications
Klystron transformers are a core component in systems that power klystron vacuum tubes — high-power microwave amplifiers that convert DC power into focused microwave energy. Varian Associates (later Varian Medical Systems and CPI) was one of the dominant manufacturers of klystrons for scientific, defense, and medical applications, and their M.E.D. (Microwave and Energy Division / Medical Equipment Division) products were widely used in linear accelerators (linacs) for cancer radiation therapy, as well as in radar transmitters and particle physics research installations. A custom transformer built to Varian M.E.D. specs such as this one would have supplied precisely controlled heater and high-voltage power to the klystron tube within such a system. QTE (Quality Transformer and Electronics) has long been a supplier of specialty transformers to aerospace, defense, and scientific OEMs, and this unit reflects that heritage. Buyers today are typically seeking replacement components for legacy Varian-based linac or radar systems, or sourcing parts for klystron test and research benches.
This Quality Transformer and Electronics Model 5564 Klystron Transformer has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The black chassis and laminated core show normal wear consistent with service use. The terminal block and winding tap connections — SEC, PRI, PRI, SEC — are intact with no visible damage to the leads or terminals. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
