Although the old output transformer SOT-M18R had won a total of two comparative test with other 18Watt transformers in "18Watt Community Center" to me, the sound in some settings was too "modern" which should not be for a vintage amplifier. So I decided to use traditional paper coil bodys and also reinforced the insulation for this transformer.
In contrast to american-made transformers all lead wires are strain relieved and insulated and the insulations on the sides is done with glass fabric.

Technical Data
Power: 20 Watt@50Hz 1,0 Tesla
Primary Inductance at 230Volt@50Hz: 480 H
Leakage Inductance at 1V@10kHz: 5,6mH

This power transformer was specifically designed for the Marshall ® 18 watt TMB. Based on the original "Radio Spares Hygrade Mains Trans".  The original 300 V was reduced to 290 V high voltage, which was very often requested. Otherwise, this transformer has the same size, iron and wire thicknes as the original. The primary voltages were adjusted to today's needs.
This powertransformer is a direct drop in replacement and fits without machining into most currently available 18 Watt Chassis. The transformer meets the required RoHS Directive and the safety requirements of EN60742.
Made in Germany

Technical Data
Sek-Power: 103 VA
Primary 0/230/240 Volt
Sec. 1: 290/0/290 Volt(AC) @ 0.12A (DC)
Sec. 2: 0/5/6,3 Volt @ 2/1A ( AC)
Sec. 3: 3,15/0/3,15 Volt 3A (AC)
 

Marshall® 45/50 Watt Power Transformer. It is suitable for all 45 or 50 Watt Marshall® amplifiers.

This power transformer can be used both for construction of a 45 Watt or 50 Watt Marshall ® amplifier. In addition to the 2 + 350 volts, it still has a tap for 2 + 325 volts. Also both voltages can be rectified by a rectifier valve or a full wave rectifier using diodes.
This mains transformer fits into the usual offered Marshall®45 or 50 Watt chassis without any mechanical works.

Original replica of Drake 784-103 for the Marshall ® JTM45 series with an additional 4 Ohm tap.

The classic JTM 45 Output-Transformer. Manufactured by the British transformer factory Drake Ltd, this Output Transformer was used in Marshall® JTM 45 Amplififiers with KT66 power valves.
As with all other replicas, an original output transformer was available, which of course was carried out meticulously and carefully. The rebuild became an additional 4 Ohm tap, the 100 Volt winding is burried and not attached by a white cable like the original.
Exact layer winding, the use of original materials and carefully stacking of the transformer laminations are only part of the basic prerequisites for an exact copy of the original. The output transformer has the original dimensions and can be easily replaced. Delivery is as shown with the silver powder coated bell ends for vertical mounting.
