Philco 46-350
#1

Hi all,

I started the restoration of my "new" philco 46-350 code 125 first of all I noticed that it had cut the power cord so I was not sure if was safe to turn it on, I opened it and remove the internals to review it I got a surprise that the radio was already modified with new electrolitic caps and some ceramic caps were also replaced, so i decided to turn it on. The philco came to live again with a very loud "hum" so I turned it off and started to look for answers, lot of responses and some of them where very helpful I found the schematics and philco troubleshooting document for this model. I also found that some electrolitic caps were replaced with wrong values so I rebuild the candhom with electrlitic caps and with proper values (30mf/150v,30mf/150v,10mf/150v,30mf/25v) after replaced the wrong ones and test the radio... "hum" disapeared but now there is no radio signal, I cannot get any radio station across all the spectrum. I used my mobile phone with a frecuency generator android app and tested the sound in volume control I got sound but still not sure if I can test all other test points without blowing up my mobile. Also after replacing the caps I got the following voltages: in R100 I get 117 | after R100A : 105 v | After R100B : 60 v | After R100C : 12.5 volts and in all tubes in the filaments I get the following values:

        terminal  |  voltage
1U5 :    1 - 7    |    1.7 v
              2      |    22 v
              3      |    15.4 v

3LF4 :   1 - 7    |    1.4 v
           1 - 8    |    2.8 v
              2      |    83 v
              3      |    86 v

1T4 :     1 - 7    |    1.38 v
              2      |    86 v
              6      |    3.3 v

1R5 :     1 - 7    |    1.78 v
              2      |    86 v
              4      |    0 v

1T4 :     1 - 7    |    1.6 v
              2      |    86 v
              6      |    0 v

Any idea on what is wrong ?

I am interested to have this radio fully working, your comments and advices are really welcome.
