    Checked out the hardware. Looks like the 2N3055 has been replaced. Nice and shiny and the thermal paste looks fresh. No real burn in on the monitor but I need to adjust the settings as I can see the red dot in the centre of the screen.

    Covid and buying new machines. Anyone holding back and waiting?

    I may have a deal in the new year, but with this covid crap still rampant, I may just hold off for a while. Anyone else waiting to purchase? Staying within my own bubble and avoiding unnecessary contact. Happy New Year everyone.

    Gyruss sound too loud.

    Again depends on the art work, and condition of the game. I know I'll have to replace the control panel artwork. It's missing some areas. thanks again for the info.
