Hi , Let me start over since I made such a mess of my original post. OK the story is I have a Crosley 124 Playboy radio that does not make a sound . I replace all caps and alot of resistors. My voltages on the tubes , starting with the: 80 pin 1 = 336v, pin 2 = 340v ac, pin 3 = 340v ac, pin 4 = 338v.
47's pin 2= 280v, pin 3 = -.4v, pin 4= 257v.
27 2nd Det pin 2 = 2.5v, pin 3 = -.7v, pin 4= 17v.
35 RF pin 2 = 247v,
24 1st Det, pin 2 = 170v.
27 OSC, pin 1 ans 5 = 12v
35 IF pin 2 = 247v.

I would appreciate anybodies opinion on these voltages.

thanks

Drew

Drew: the normal voltages are listed on the schematic at http://www.nostalgiaair.org/PagesByModel/412/M0043412.pdf

It would be helpful if you'd make up a little table that compares the voltages listed on the schematic to those you measure. Instead of pin number, list each specific tube's element, e.g., plate, control grid, etc. List each tube by function, e.g., oscillator, 1st detector, etc.

Do all the tubes light up? Are any of the IF xfmr windings open? Ditto for the audio output xfmr.

Touch the control grid of the #27 2nd detector with the tip of a screwdriver. If you get a hum, then your audio section is probably functioning.

Replacing caps and a lot of resistors will seldom make a dead radio come to life and may introduce inadvertent wiring errors, compounding the original problem. I think it's usually better to just replace the filter caps, and then start troubleshooting before wholesale replacement of caps, etc. Once you get the radio working, more or less, then you can check to see that it still plays after each cap is replaced.

Drew, I noticed that you seem to have no plate voltage on the 2nd detector. You need to troubleshoot this and find out why.

Hi,

It's amazing how the little things matter. I was going a little nutty trying to figure this radio. I had the radio power up and I just decides to move the tubes---BANG the radio came alive. All it was , was a bad connection on the 35 RF tube.
Now that it is working , it still didn't sound right , so I track it down to the speaker transformer. I have a couple laying around , but I do not know what the wattage is of the original transformer. If anybody knows please jump in.

thanks
