Ok guys, JustRadios has me worried after reading an article about purchasing resistors and I hope that I haven't made a mistake in purchasing from Amazon before finding Just Radios. Long story short, I have replaced all resistors, Caps and safety caps installed. Also connected a polarized power cable which is another story to come.
Today I took a chance and powered the radio up hoping that it didn't blow up etc. The dial lights came on which was good, then the speaker buzz started followed by a little smoke. I immediately unplugged it. Checked it and didn't see anything so tried again and this time I could see a resistor smoking. Now I'm fighting to find it on the schematic but in the meantime, I have re-installed the old resistor.
I am curious though if the issue was indeed the resistor or possibly a loose wire also connected to it? The speaker wire goes to one end of the resistor in question, and I had temporarily attached it to the lead while testing it and not soldered down.
After installing the old resistor, I also soldered down the speaker wire and did a test run and the radio powered up with no smoke. Maybe someone can give some advice, I would hate having to replace all the resistors again.
