WPDLXFMR-2 Transformer

  • 45 watt Effects Power Transformer
$25.20

Pedal and effects power supply transformer, Eight 11 volt, 300mA windings and one 9 volt, 2 amp winding. 120-220-240 VAC input. This is a transformer, NOT a power supply. The output is AC, not DC. You must build a power supply that converts AC to DC in order to use this transformer.

Weber transformers and chokes are replacements for vintage units and for use in new designs. Some of the power transformers have increased current capacity in the filament winding and the high voltage winding. Some have multiple high voltage taps for use with or without a tube rectifier. Transformers with bolts are supplied with #8-32 zinc plated nuts with integral star washer. Others are supplied with two bright zinc plated #8-32 phillips head bolts and nuts with integral star washers.

Please Note: Fender amp model names and transformer applications refer to Brown, Blonde, and Blackface/Silverface series chasses unless the model name is preceded by 'Tweed'.

We have discovered that on some vintage amps, either due to chassis changes concurrent with transformer supplier change or for some other unknown reason, some chassis PT cutouts vary in width and length. In those cases, our lower endbell might be slightly larger than the hole and must be removed to fit the chassis PT cutout. The bolt pattern fits fine, however. This appears to occur in some Fender BF and later Deluxe and Vibrolux models. The transformer will work fine without the bottom bell installed.

Transformer Testing: The industry standard testing called HIPOT Testing (it stands for "High Potential") applies a high DC voltage between each transformer lead and the case, and in some instances between individual leads. The idea is to test for shorts that occur as a result of arcing between the leads and the winding wires in the transformer. This is particularly important when testing output transformers because of the potential problems associated with flyback voltage from the speaker or speakers that gets multiplied up in the primary of the output transformer. Flyback and the resulting arcing can ruin an output transformer as well as create carbon paths on the output tube socket between pins, leading to a failure of the socket. The industry standard HIPOT DC testing voltage is 2000 volts. Due to the nature of this market and the potential for very reactive loads being used, Weber HIPOT tests all of its output transformers at 4000 volts DC.

Awesome for CLEAN pedal power

Awesome for CLEAN pedal power

I bought one of these in 2010 & designed 9 channel discreet power supply for my pedalboard. The other guitarist in my band has nothing but noise issues with his 'Brand X' pedal board, so bad that our sound tech is constantly turning his channel off between solos. Pretty bad for a $250 pedal board, but mine is dead silent no matter what kind of power we're running on. The transformer runs quiet, clean & flawlessly. Granted, it's only part of my power rig but I absolutely love it & run one effect as well as my wireless on each 9.5VDC line, so I'm never remotely close to any kind of power sag. I regulated each line to 9.5VDC after the bridge rectifier on each channel. I'm about to build another pedalboard this summer (2017) & one of these transformers will definitely be at the heart of it.
