Phil......
Always....always.......C308......220ufd/35volts.
Due to the fact that these 2.2ufd/35 volts are timing capacitors.....should
never use higher than 50 volts.....discharge time is too great with a
250volt cap. I have never tried to go higher for that reason,,,although you
may be lucky.
BTW...you may have to change the vertical O/P IC too.
