Marshall 4140 Amp question

My thoughts are that a guitar amp which spends most of its time driven
to distortion will have transformers able to take considerable abuse
without failure. So, I expect it to be much lower than an audio amp
(which I will check anyway).

I found this in the archives, putting
matching transformer henries ohms
as keywords in google usenet, on a guitar group
"Primary winding, by direct meter measurement with a Fluke 8600-A:
DCR Blue side to center tap = 44.91 ohms
DCR Brown side to center tap = 51.03 ohms "
I assume DCR is DC resistance of that matching transformer.
Mine was measuring 14 and 15.5 ohms which seemed a
bit unbalanced but no worse than this example
