Hi, could anyone kindly tell me what is the correct model number for the National HRO audio transformer shown in the attached image? I would like to find one (if possible) for a National HRO-MX that I have, waiting for restoration. Thanks.
Daniele

Daniele - I took a look at my two HRO's. One has a Kenyon T-104 transformer, apparently 7K primary and secondary windings for both 500-200 and 15-8-4 ohms.

Read through to find where 'audio transformer' is mentioned.
Good luck!
