Oh boy. Hope you didn't pay a whole lot. Not looking good. Post photos after you get all that soot cleaned up. Output transistors should still be good. They're getting hard to find nowadays.So I have bought something nice to restore again a Yamaha B-6 that has been on fire the inside smells terrible
Got a few under my belt as well.Yes , very well known problem
I have made many B6
I like your spirit of adventureSo I have bought something nice to restore again a Yamaha B-6 that has been on fire the inside smells terrible.
The capacitor that should have been replaced in the recall on all 220v models has caught fire and damaged the print.View attachment 1332170View attachment 1332172
are there any unobtanuim parts in the B-6? besides the PSU boardsGot a few under my belt as well.
One that I know of. It looks like its probably charcoal. IC401 IG04080are there any unobtanuim parts in the B-6? besides the PSU boards
Is this damaged board working as it should now?not new but working fine again.
It is the rifa capacitor that was completely exploded and left a lot of firetracks, it is not my first amplifier that I repair but my first B-6 I now have solder all the print tracks for strength and in the meantime clean the print with some oven cleaner and let some glue flow here and there to give the print some strength again.
There has also been someone for me who has ventured an attempt, there is also a resistance of 33k 2 watt missing.
a new fuse holder, resistors and capacitors soldered and this is the result, not new but working fine again.
Now just clean the amplifier board and replace 2 wrong transistors in the power control.View attachment 1332568 View attachment 1332570View attachment 1332568 View attachment 1332570
