Default Fender Bandmaster TFL5005D Reverb Tank

Hi


As posted earlier, a JCM2000 DSL50 had its Reverb tank broken. Upon checking I realise that I have an old unused reverb tank that belonged to a Fender Bandmaster TFL5005D, and wanted to use this as a replacement tank. I used my DMM to check the input and output coil resistance. The output reads approx 175ohms, but the input coil reads about 1.2ohms. This reading seems odd. Does it mean that the input coil has shorted. Please advise.


Thanks

No, not necessarily. Probably it's just a low-ohmish driver input. I dont know your specific item, but I know from Accutronics that they manufacture low, medium and high-ohmish devices as well.
Best regards!

It's a coil. The nominal impedance is rated mid-band. The impedance in bass, or DC (ohm meter) is much less. Roughly 10X less. This is like a 10 Ohm to 1.5k-2k tank.
