Wanting to replace the C26 cap on a sol. driver board. Happen to have a 220 mF 350 volt cap. Can I replace the existing 150 mF 350 V with this new cap ? Although its okay to go higher for the C23 cap, I wasn't sure about the C26.
Yes, 220uF value will be OK (at 350V), to replace the original 160uF. Rated 85 C temperature or higher.
But I would recommend to not go higher than 220uF, as it will otherwise stress the four small diodes on the rectifier board, at every power-up.
Cheers, - Sylvain.
Looking for 1966 Bally Capersville, 1967 Bally The Wiggler, 1981 Stern Viper, 1986 Pinstar Gamatron, 1986 Williams Grand Lizard, 1991 Williams Bride of Pinbot, and a few others. Cash or some trades available. Could also repair a machine of yours +/-$ if needed, in exchange for one machine on my want list, non-working/unshopped welcome!
I noticed that Sayal has some 150 mF 350 V. Although this is a little underrated, would 150 mF be preferred over 220 mF in the future ?
It is usually never a good idea to replace a cap with one that is underrated.
In this simple filtering application for the displays' power supply however, since very close to the original value, I bet it would work just fine.
I personally would put a 220uF if given a choice, providing that the replacement cap has dimensions to fit the board, and that the price difference is small with the 150uF.
Cheers, - Sylvain.
