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.

Genuine Marshall™ 100 watt output transformer for JCM900 and JCM2000.

35VA chassis mount Power Transformer for isolating equipment from direct connection to the power line. It 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. These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B insulation system.

The LEHLE TRANSFORMER MZ is the ideal component to avoid hum loops without degrading the sound. It achieves this through galvanic isolation of low to mid impedance audio signal sources. It can be used as an input or output transformer, for balanced or unbalanced signals.

• Over designed for single ended tube output circuits (triode, tetrode or pentode tubes).
• Enclosed (shielded), 4 slot, above chassis Type 'X' mounting.
• Frequency response at least 20 Hz. to 20 Khz. at full rated power (± 1 db max. ref.

The UBT-2 from One Electron is the same size and power (15 watts) as the UBT-1, but has a higher primary impedance suitable for single tubes running at B+ voltages of 400 to 500 volts, such as: 50, WE 300B,etc.

Genuine Marshall™ 30 watt output transfomer for JTM30.

Genuine Fender power transformer designed for use in the ‘65 Deluxe Reverb as well as the ‘68 Deluxe. Made to original fender specifications. 120V Primary

Dual 117/234 VAC primary, 50/60 Hz. operation. 220 V series, 110 V parallel secondary.

• Primary 115VAC, 50 / 60 Hz., Secondary 115VAC
• Provides complete circuit isolation.
• Electrostatic shield between primary & secondary to greatly attenuate surges and noise.
• Hi-pot tested to 2 KV RMS.
• Circuit breaker in primary.
• Standard 3-wire, grounded plug & receptacle.
• Input (primary) connected to 5 foot long cord & standard North American plug (NEMA 5-15P).
• Output (secondary) connected to 1 foot long "pig tail" cord, 3-wire, standard North American grounded receptacle (NEMA 5-15R).
• North American Mark of Safety - C UL & UL listed (File #E211544)
• Indoor use only
• Remember - These units do NOT convert line frequency

• Universal primary with taps for 100, 120, 220 or 240 VAC, 50 / 60 Hz. (Except the 260A6 which is 117V, 50/60 Hz only)
