Another stupid problem.
Just recapped the analog board out of my classic
When i first powered it up I got a wavy chess board display
after a minute or 2 I noticed the 'wavy' display was not as wavy
waited a bit more and it started to chime
it eventually boooted up perfectly
I plugged it out for the night and took some voltages today
+ and - 12 volts are good and steady
But the +5 volts starts out a 4.32 volts.......... as i leave it on i see the 4.32 volts slowly climb up and up - when it gets to around 4.5 it starts to chime ........ after a few minutes its up to 5 volts bang on and the machine runs fine
I found electrolite under the 2200uf caps as i replaced them
I didnt have a 1uf 50 volt radial so i used a beed tantulam cap
I didnt have the 470uf 50 volt so i took it out , checked its value ( looked ok ) and put it back
i have rechecked all my work and everything is good ( as far as i can see)
just having no luck lately !!!
anyone ever have this before ?? - 5 volt starting way to loo and then slowly climbing up to the 5 volts !!!
