Used, tested electrolytic capacitors. I have 6 of these, four are 2.5" diameter by 5" long, two are 2.5" by 4" long. All are 120000mfd, 15VDC. $20 each or make an offer on the lot.
A note about testing-most DVMs can test capacitors, but not in this mfd range. So, I used the time constant method, charge the capacitor from a known starting voltage to 63% through a known resistance. From the time required a good estimate of the Capacitance can be made.
