Restoring a Philco 38-1
#4

PS: You also have a 1mfd - 3mfd which I missed on the first go round. I believe the latter can be lower voltages, check the old cans for voltage rating. You can get 1mfd and 3.3mfd at 450 volts also. On the voltages you can go as high as you want the only draw back is really overkill and money. By the way, the first three (10,8,18[2 cans]) should have insulating collars (cardboard wrap) on their base to keep them off the chassis ground. That becomes your B- for bias. Don't connect the negative leads of those capacitors to chassis gnd. You may have to add a small terminal strip under the chassis to hook them up correctly in the circuit. If you are going to stuff them in the cans, save that little terminal lugs that are fitted snugly between the can and the insulating collars. Cans are aluminum so instead of soldering the lugs to the can they are press against it by the insulators and thus make contact with can, they are sheet metal and wires can then be soldered to to them.
