Features:

• Designed for driver use ONLY in single ended tube output amplifiers. These units replace coupling capacitor circuits for improved sound.
• Closed style with minimum 8" long leads.
• All models use bifilar wound windings for exceptional coupling and bandwidth.
• Minimum frequency response 20 Hz. - 20 Khz (± 1db max. ref. 1 Khz.).
• The core is gapped to support the specified D.C.

Studio grade frequency response: 20 Hz. - 20 Khz. (+/- 1 db, ref. @ 1 Khz.) minimum. Excellent frequency response utilizing a 80% nickel core providing high permeability combined with low losses. Designed for maximum bandwidth, lowest distortion at +10 dbm power level or less. Plated steel cans, adjustable height case bracket.

• Both series operate on 50/60 Hz current
• Low profile, split bobbin design.
• Dual winding secondaries, non-concentrically wound
• Units are designed so that all windings must be used
• Low primary to secondary coupling - no electrostatic shield required.
• High insulation - Hipot of 2,500V RMS.
• Class B insulation - 130 degrees C.
• c UL us recognized
