I'm looking at a solid state Fender Deluxe 85 and everything works and sounds great except that the reverb doesn't work. Looking through a bunch of websites I found a vendor that lists a replacement reverb tank for this specific amp as having 800 input impedance and 2575 output impedance. On my reverb tank, my DMM reads 56ohms on the input and 2000 on the output. Its an Accutronics tank but there is no code on it so I can't look it up. Do you think that this is enough info to declare the tank officially defective. I gotta assume that the vendor of the tank has listed his product accurately and that my DMM isn't totally out to lunch. 56 ohms of resistance is a long way from 800 ohms of impedance.

You are reading DC resistance and not AC impedance. It's hard to get an accurate read on a reverb tank other than a rough estimate using an ohmmeter. Generally about 25 to 60 ohms input side to few to several hundred ohms on the output side is generally what you'd see on an IC driven tank. The tank is usually an 8EB2C1B.
