Re: What did I get myself into? Murphy A40C.
I assume this was converted somehow when original speaker was replaced. I couldn't tell you if the output transformer was replaced either and if the one in the pic and my chassis is original or not as the Axiom was fitted well over 40 years ago and according to previous owner radio worked fine when he bought it 43 years ago.
If the values in the service manual are for resistance than this actually shows 124ohms / 171ohms.
Not sure what the original field coil was replaced with, not sure what to look for either.
PS
The temp Wharfedale 100W 6ohm(not 8 as I thought earlier) bookshelf speaker actually sounded very good, just a bit quiet.
