I am restoring a 1940 Philco model 40-195 and I'm having trouble sourcing the two .003mf 1000 V capacitors connecting from the plate of the two output tubes (42) to ground. I have one .003mf 630 V capacitor that I sourced from a company in Canada (I miscounted when I ordered and so only ordered one when I should have ordered two). I'm not sure whether the 630V rating is enough. Also, due to a dispute in a past order, the Canadian company invited me not to order from them again.
I then ordered what I thought were .003mf 1500V caps from an outfit in Bulgaria on eBay. When I received them and tested them, they showed .012 mf instead, not the .003mf I expected. They are labeled "3n0 K MKPI 1".
1. Can I use the one .003mf 630V capacitor that I have?
2. Is it safe to use the .012mf capacitors that are supposed to be .003mf?
3. If I need to purchase the right capacitor, can you recommend a source? (I've checked mouser.com, digikey.com and others.)
4. If all else fails, is there a way to make the required .003mf capacitor by combining other caps?
I'll attach some pictures. Thanks in advance for your help.
