Small 42TM018 audio transformers with a 10KΩ:600Ω impedance. This transformer is a popular choice for pickup simulators in various effects such as fuzz pedals. The leads are soft metal wire and can be adjusted to fit a variety of applications. RoHS compliant. Rated for 200mW.

• Primary: Universal - 100, 110, 120, 200, 220,230, 240 VAC 50/60 Hz.
  
  • NOTE: units are designed to operate with BOTH primary windings engaged.
  • See primary wiring information under resources.
• Bias Tap: 50 VAC tap from high voltage secondary C.T. (except part number P-T379WX - uses a separate 60VAC 0.2 Amp winding).
• Highpot tested: 2,000 VAC
• Faraday Copper Primary Shield: Our electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries (shield is internally grounded to the end bell).
• Windings: Concentric wound for low stray field and low noise.
• Models: This series is an upgrade from our P-T263-X range of units PLUS 2 models designed specifically for 300B tubes (Part Number P-T300BX) and 2A3 tubes (Part Number P-T302AX).
• Finish: Black powder paint to match our P-T1650X series of output transformers Units can be run full wave bridge or full wave C.T.
• Conservative designs - CSA certified (209651).

An Isolation Power Transformer for isolating equipment from direct connection to the power line. The transformer is constructed with non-concentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection, under normal or overload conditions, between the primary and secondary windings.

• Universal primary with taps for 100, 120, 220 or 240 VAC, 50 / 60 Hz. (Except the 260A6 which is 117V, 50/60 Hz only)
• Designed for preamps, low power amps, general replacement, test equipment, etc.
• Economical, open frame, chassis mount - two hole (.187 dia. = G) channel bracket (figure #1) or four hole mounting (figure #2).
• Units include a Faraday shield between the primary and secondary windings. Our electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries.
• Minimum 5" long leads.
