Philco 38-3 ?

[butch4695]

i hit a couple of yard sales yesterday and came across an old philco 38-3 and the guy was asking $5 for it , so i said what the heck and loaded on my truck and took it home . he said it was working about a year ago and he put a new power cord on it .well the power cord he put on was a new cord spliced onto the old cord and the old cord part looked to be in good shape and the splice looked to be safe enough to try it out . so i plugged it in and turned it on , and it worked , i was listening to a local broadcast of a minor league baseball team for a couple of minutes before i noticed that it started to smell like it was getting hot . so i turned it off and unplugged it . i am a total newbie to tubes and radios like this , so what i am asking is what should i do with a piece of equipment like this if i would want to get it back to safe listening operation , as i really don`t know anything about them ?
