Original caps 4.7 microfarad 6 or 10 V electroylitcs (some were 6 volt, some 10, and I've even seen one of each on the same board!) I'd like to know if the black rubber end seals were blown out of your caps. Please reply. Replace with 4.7 to about 10 microfarad (whatever you can find ) TANTALUM, not electroylitc, caps. Get at least 20 Volt units, larger (like 50 volt) if they'll fit. // Mark [Quote snipped by moderator]
