P-T118944 Transformer - Hammond, Radiola III-A Replacement Audio
Developed in response to requests from RCA Radiola III-A collectors. The original transformers are usually found with open" windings due to the fine wire and high turns usedcoupled with age. This is a universal replacement type - it will replace any of the three audio transformers used (1st audio driver2nd audio-phase splitter stage or output transformer)by correctly connectiong the 5 lugs. A pin out and connection diagram is included. The cases from the old transformer will fit this new unit. The terminal board is a duplicate of the original.
Key Features
  • Primary: 4000 turns, #41 wire (lugs 4 & 2)
  • Secondary: 12000 turns C.T., #41 wire (lugs 5 & 1lug 3 is C.T. connection)
  • Termination: Solder lugs on a 1 3/4" x 1" terminal board with 4-5" connecting leads
  • Size: 1-7/8" long x 1-11/16" wide x 1-3/8" deep
  • Lamination Core Size: 5/8" x 1/2"

P-T260X Transformer - Hammond, Plate & Filament
  • 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.
