Damon: Thanks for the reply....please note, the primary winding is OPEN. Values I gave you are from SAMS. I don't know the voltage on the secondary winding as it is not marked on the schematic. The voltage from the secondary winding goes into a full wave rectifier to supply 27V D.C. for the sound. Age of set - 15 yrs. old. Good pic, beautiful cabinet. Customer wants it fixed. Thanks for any further insight.

I'm sure the 2ndary windings have to be a larger wire, since it's higher current on the 2ndary-less ohms. Now, do you think working on a CTC 130 chassis is a good thing to do???? It's what, 2 years old? or 20?

Primary reading 28.6 ohms, secondary reading .9 ohms. Primary is open. NLA. Where could I purchase one? Has iron core. Surely there must be a sub. TIA Kenny > Kenny Barnes TV > 928 S.
