These values aren’t overly hard to find if you look at “the usual suspects” as venders are usually known as on the vintage auto forums I belong to. I just placed a large order to this gentleman a month ago including an assortment of high&low voltage axial and radial electrolytics. Also it isn’t mentioned what “flavor” IE Polyolester, Polypropylene, and my inquiry was answered with polypropylene for 95% of the values I ordered. His (Sal Brisindi) prices are lower than our Canadian supplier in Eastern Canada AND out of protest for being charged US prices and currency from a Canadian seller to a fellow Canadian I might add.
My order was large of the axial “yellow fellows” of great quality and electrolytics and he mentioned what were very common high use and not so, low use so we adjusted accordingly. Oh and shipping was also free because I placed a large order but reasonable amounts most likely will qualify. Other than that I find the little green, brown red etc. Mylar Polypropolyne style are usually dirt cheap with excellent selection, quantity, and voltage from eeevilPay with free shipping from some of the Chinese suppliers. Quantities over 100 for $4-$8 These will work good in my block capacitors found in my Philco 444
Anyway enough of that and on to the values and substitutions………….
Correct me if I’m wrong? I was warned about sizes of electrolytics in the power supply possibly from this forum? I used to think bigger was better especially reducing hum and this can be true but the larger capacitors when totally discharged can be too large of a load during recharging at startup on the rectifier tube and in automotive can also be a strain on the vibrator and transformer. Apparently some of the very old rectifier tubes can possibly become damaged from the momentary current spike as the capacitors charge up. Let’s see what other members know about this if I’m wrong in some areas.
