Hi,
Good day, im ojo.
Re: Technics su-7700ii
Problem, there are some missing parts on the board.
Resistors
R237
R238
R241
R242
R245
R263

Is there anybody here who can help me find the resistance value of above parts.

Thanks in advance. Any help will be much appreciated.

Are you sure they actually belong there?
It is not uncommon for one pcb to be used for more than one application and not have every component installed.

Does it work?
 
Little more info! The parts just don't disappear. Was it like this when you got it? Where did you get it? Do you know if or when it worked at one time in your possession?

Got any pics of what we're talking about here? I can only imagine a previous owner pirating parts for something else before you got ahold of it.

Unless it was a factory revision. we're just running blind.

Hi fi engine has a 7700 but not a 7700II so not sure if the 7700 schematic will suffice?
 
Sorry i was unable to answer promptly as im fixing another unit. I just drop by and give a try maybe someone will ring with the identical unit who is willing to have a look at the missing resistors on mine. Its positive someone gone thru this as blown fuses were jumpered. There are also discrepancies on parts list values on the su-7700 SM against the actual board. Parts just dont dissapear as you have said. They were taken out probably by someone who tried to fix this before. I dont know the history as it was just drop by a dumpster regularly pass my place. This is lenghty..thanks for your effort. Just have to leave this unit for a while.
