Hi i am john... i have a marshall 100dfx mg series... it is blowing fuses... its tranformer is needing replacement... i need to get a new one for this amp . who can set me up? thanks john
There are MANY more likely components than the transformer that will cause the fuse to blow.
Most common are filter capacitors, rectifier diodes, and shorted components in the power amp section.
Transformer failure is very UN-likely. Have a competent electronic tech troubleshoot the unit.
When testing the unit, put a 150 watt light bulb in series with the power line... saves fuses during troubleshooting. This limits the current so one can analyze the real cause of the problem.
