R3,

Let me ask you this: how much, if any, experience do you have in radio repair?
If you don't have much, I suggest that instead of powering up radios and see wires melt and amps drawn, you step away, think a bit, and develop a plan of testing (this is where we can help) that is safe and methodical.

One way that safe and methodical is not, is turning the radio on without making sure it is safe and ready.
And while this is a transistor radio and does not work with dangerous voltages, so electrocution is not likely, this still can put things on fire.

My suggestion:

1. Whatever you have replaced: trace it to the schematic and make sure you followed what's in it.
2. Check the power in for shorts, where it goes to the rest of the radio (In 5TPO it is 18 ancd 19 to GND).
3. Check every transistor for integrity and leak. My favorite is an analog arrow multimeter set on Ohms. B-C, B-E and C-E.
Do not power before you make sure all above is good.
4. If after power-up it still draws excessive current, try to see what draws it. There are ways. From smelling, running the back of your palm or back of fingers near parts and see if anything is hot, to measuring voltage drops across the circuitry and trying to see what drops it etc.

It is fairly simple: transistor schematics are way simpler than tubes to work with, but transistors are at the same time are very easy to kill, unlike the tubes.

PS. for the TP12 in 5TPO use the X8 diode's Cathode (bar).
