the above photo shows the electrolytic capacitors that were a direct replacement for the ones that blew in the first instance (10uf 16v)

The strange thing is that if you look at the board and according to the schematic i have they should be capacitor ceramic tubular 102pf 50v?

i am an idiot

You need to check the voltage across the capacitor.  If there is more than 16 volts across it, that is probbly why the first ones exploded.

C111 are, according to the schematic what should be where the electrolytics are.

102uf = 1000uf = 0.001000 f (micro =10^-6)

10pf = 10pf = 0.000000000010 f (pico =10^-12)

If they were planets one would be Venus and the other would be Neptune.
