Need reverb tank specs for Harmony H430

[fredcapo]

Hi. A friend asked me to look at his harmony h430 amp. Reverb not functioning. I have not had it on the bench yet, but cold measured the dc resistance at the two rca jacks; 2 ohms and 270 ohms. Not sure which is in or out but thinking the 2 ohn reading indicates a short... will have it on the bench saturday but thinking I have some spare tanks to swap in, but would like to know the impedance of the original. (I could attempt to open and test the tank transformer) Thanks

That tank is transformer driven (like classic Fender) so those numbers sound right. The 2 ohm resistance would be the input end.
