Cap replacement on 37-630X console
#1

Hello,

Here come the first round of questions from the newbie. I have schematics, parts locator and parts list my new 1937 Philco. Verified all tubes are the correct tubes and functioning. Radio plays on all 3 bands, but read that the very first thing to do is replace all caps.

1} Should I replace all caps including the mica caps ?

2} Capacitance values are listed on the parts list, but not voltage ratings. How do I know what voltage to get ? The electrolytic Radial caps currently installed show a voltage of 450V is that correct ?

3} How can you determine the voltage of all other caps without removing them ( I can't see the V rating on them }, I would like to order all of them prior to removing any of them and then replace them one at a time ( carefully ).

Would appreciate any input on a logical way to go about it......

Who makes a good quality Cap ?, etc.

Thanks,

Kurt
