The winders are available with a range of standard coil formers or may be customised to meet match existing Reel sizes.

Damage to the magneto coil formers indicated that the rotor had been operating out of alignment, increasing the torsional loads within the shaft.

The adjustable ferrite cores, 'slugs', inside the coil formers L1/L2 and L3 will be positioned at various places through their tuning lengths during setting-up.

Later when you have the slug in the coil formers L1/L2 and L3 finally peaked, you can fix the slug in place in the coil.

G.H Maughan was founded in 1959, and concentrated it's manufacturing output to the production of relays for Metrovickers, who in turn produced Coil Formers for the English Electric Company (now known as G.E.C).
