zenith 7s363
hello to all.i have a zenith 7s363.this set worked for about a year now.changed a couple of caps to get the hum out and used sparingly.nice tone and volume.i stripped and refinished cabinet.it looks very good!i turned it on today and the trranformer began to burn.i quickly unplugged.flipped the chassis over to have a look.all was well.checked the tubes and let it cool down.later turned on and it played with good volume for a short time-approx.30 seconds.then the transformer began to burn again.where do i start guys?thanks!
