Well,
I can understand that for sure, but the resistor looks pretty 
distinctively yellow, brown, black stripes with the last being gold 
putting it into a 5% tolerance. According to my chart, the actual spec 
calls for a 47k which would be yellow, violet, black and it could be 
quite possible the brown stripe was violet but it looks to be quite a 
stretch from looking at this thing. But, this is good to know because in 
the future I will keep that in mind and not take the color on the 
resistor to be quite true if it is fried. Even at 41K with a 5% 
tolerance, the resistor I took out wasnt even close to the spec called 
for in the manual. After closer investigating under the chassis, I see 
someone has been messing with it and it has some strange areas that I 
need to look at closer. The radio works fine, but, there is a cluster of 
diodes and resistors that are just soldered in mid air around the power 
supply circuitry. So, Im thinking the owner who did this must have had 
some power supply issues and rewired to his liking. Boy, is it a mess. 
When I become a bit more secure about my troubleshooting, I might tackle 
that project to get it back to square one. I would love to see what a 
stock radio looks like compared to mine. Some pictures of the 
undercarriage wiring of one that hasnt been modified would be nice to 
see to compare to mine. The pictures in the manual arent very clear so 
it is hard to tell what this mess is supposed to look like. Anyway, I 
feel good that I was able to find this little issue and can move on to 
something else in hopes of improving this old radio.


Thanks-Bob-W0YBS
