OK lets back up
Looks like an SK1961W or P
It is the power supply ( 99.5% ).
Did you change the 3.5mfd oval cap ?
Did you change the multi section filter can ?
Double check the values you used & the wiring.
Be sure the can caps are well grounded. ( all negative ends tied
to the metal can point )
Last possabilities are VERY remote that almost never happen
to any set.
Shorted choke.
Open or leaky rectifier.
If it uses an ON/OFF triac it could be that.
BTW Did you ever find what burned ???
