Transformers & Chokes

• Replacement for Yorkville/Traynor amplifiers
• Designed for drop in replacement of original units.
• Physically, parts were designed to look similar to original factory units (where possible).
• Material used & design specs. were kept as close as possible to the original part to preserve the stock "tone".

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.

Features:

• Small, economical, open, two hole horizontal bracket mount.
• Insulated, color coded flexible leads, 4" long minimum
• Frequency response 150 Hz. to 15 Khz. (+/- 1 db, reference 1000 Hz.)
• When operating at impedances below nominal, power capability and the frequency spectrum are proportionately lower, conversely, at higher impedances power capability and frequency spectrum will be proportionately higher.
