The Lundahl LL2777B output transformer (OPT) has been specially designed for the Elekit TU-8200R. It replaces the stock OPTs that ship with the amp. Add them to your TU-8200R and a great amp becomes quite magnificent.

Output Transformers (2) for Elekit TU-8200R tube amp. Includes Elekit mounting harnesses, PCBs and adapter plates.
The quality of a tube amplifier’s OPTs is extremely important, especially so for single-ended amplifiers. Design is all important as an air gap in the transformer is needed to prevent transformer core saturation, which would cause audible distortion and other problems. Herein lies the challenge: having an air gap lowers the inductance, which compromises low-frequency response yet to increase the inductance requires adding more windings, which adversely affects the high-frequency response.
