Well I think I found my bad reverb problem. I bought a DC10 combo. The owner had the white and gray cables disconnected. The reverb tube is good, and the tank looks good on the inside probably due to mesas little reverb tank cover. Can a reverb transformer blow just like a OT would if it had no load on it? I think the tank is 8Ohms so I would think the transformer could blow just like a regular OT. If any one else thinks this is my problem where can I get a new one. I see mercury magnetics has reverb transformers for fender amps are any of them the same as my DC10 ?
