Hello everyone, long time follower of the youtube channel, but first time posting on this forum.
Im by no means an electronics engineer or anything like that, i would consider myself a hobbist, and that would be a very generous way to call it. In any case, I own a Roland D-550 rack mount synthesizer from 1987, which works fantastic, however, the LCD backlight died about 5 years ago (its the old EL type fluorescent 2x40 HD44780 compatible type). So i finally decided to replace the LCD display with a new led backlit one, and that went smoothly.
The question is, since this unit is almost 30 years old, i thought it would be a good idea to replace all the capacitors on the PSU and i wanted to ask the experienced people here how would i go with it:
should i replace every single cap with new ones ?
are there some very specific ones that i would definitely replace ?
should i just ignore the fact that they are 30 years old and keep using the unit without worrying ?
I attach here a schematic of the PSU of this unit, and maybe you guys can give me some advise regarding this. Thanks in advance!!!
