Hi everyone!

 

Got box from Ebay AS-IS, damaged, no power, bunch of loose parts inside

Opened it up today, - power supply board shattered into pieces. :thumbsdown: :

Will try to restore it, but will need schematic or maybe even better, close-up picture of the board.

If anyone have it or can upload/PM, will be greatly appreciated.

I goggled it and nothing came out.

What I think happened, is box was dropped and transformer got disengaged from the screws and pushed on the board from inside.

Rest of the components and covers are OK.

That should be the same PSU board as that found in the earlier GF-555 as the differences between the two are all in the cassette decks and related boards. 555s are commonly found for next to no money on eBay in poor condition and that part is something that will be likely to survive in working condition if the box hasn't been abused that way. My 555 is original in that area apart from the smoothing block and they're large caps that are easy to change as required so maybe you'd be best off looking at damaged 555s as a source?

;-)

 

The manual for the 555 and 666 is free from HiFi Engine and I'll upload a copy of that here if there's not one up there when I go to check..

 

OK, there's now a copy of that manual in the forum downloads area, right HERE.

Wow!

John you are a great member here! :hooray:

 

I've fixed a shattered power supply board using jumpers, 2K epoxy and plastic strips with tiny nuts and bolts to hold it all together

Damage happened because the item was not well packed. Transformer got detached from the board along with shattered pieces of the PC board. Since I found  all those 5 pieces inside the box it was pretty easy to solve the puzzle.

I have a power board from a 555 right here.  It's yours, if you want/need it.  ;-)

That's exactly what happened here, and once I got my hands on 555 service manual, I fixed it with jumpers the same day.

Hello.
Does anyone have a spare main circuit board for the 666?
Thank you!
