Купить 5K: преобразователь привода 6F6 6P14 6N11 12AU7 и других электронных ламп могут пройти DC 25mA, на выбор два железных ядра.

Electron tube 5K: 5K single-ended drive transformer, suitable for 6F6, 6P14, 6N11, 12AU7 parallel and other electronic tubes to promote the use of high power tubes in the later stage. The primary can pass DC 25mA.

2 terminals for primary 5K and 2 terminals for secondary 5K, can be customized according to requirements! Imported second-hand EI57 Z11 iron core is wound, with two thicknesses of 38mm and 43mm, each with a thickness of 0.35mm, fixed by the British Red Bull clip. High-quality oxygen-free copper enameled wire winding, nylon frame, using fever winding method, expand the frequency response and improve the quality of parameters. Secondary winding reduces internal resistance to improve driving force.
