41-608 with BOL changer
#8

Hi Gary,

I've completed my recap and the radio sounds great.  Still have plenty to do.  My BOL bulb works with 3 three volt battery source, but not when connected to the chassis leads (and the selector switch set to phono.  I did trace it back to the OSC transformer.  Did you ever check the resistance to ground at that point?  I'm reading 0 (ZERO) while I thought I'd get least .5 ohms.  The OSC trans looks OK on visual inspection, and the radio is working - I get stations when I plug in the speaker.  I'm thinking it is really probably OK.  But when powered, I get no voltage on C3.  Do you know what should be there?

If I may ask, the trimmer is closest to the chassis, correct?  That part has three adj. caps in it and that is what I believed I traced it to.  (Gee, I guess this  assumes that they were consistent at the factory in their wiring.) Did you ever check the resistance to ground at that point?  I'm also reading 0 (ZERO) while I thought I'd get least 2 ohms ( 1 + 1.1 per the schematic.)  (from 11B). It looks like it hasn't been adjusted since it was first sold.  I had to clean out the dirt from the trim screw head.  Could it really need adjusting at this time.  I did not replace this cap givin the integrated part it is in.  I was thinking of giving it a blast of DeoxitD5 and letting it dry.

I did this testing with the speaker unplugged and the turntable off.  But it looked like as long as the selector switch is on phono, I  should get the bulb on.

This is all new ground for me.  Any guidance you can give will be appreciated.

Thanks & Regards,
Gary
