peter!

much obliged! but unfortunately, the pic seems corrupted???

i have tried a few browsers and no luck...

thanks so much, 

Works on my Firefox. I'll try doing something with it.

Try this one. It only shows the ICs involved - not the whole PCB.

peter and geoff,

many thanks, that pic cuts right to the chase!

(the previous one took me to a dealer login page)

i will report back asap, but i am very busy at present... hope to have the 8000 on the bench perhaps midweek???

regards,

gents,

my apologies... "midweek" ended up being this evening...

well, i turned on the bm4400 in the background, grabbed my granny glasses, and heated up the old soldering iron!

plugged the board back up, plugged it in, saw the standby light up, pressed P4 (my fav preset for some reason) and guess what?!?!

it worked!

the bm8000 has been brought back to life! it works now just as it was supposed to! i will play it over the weekend to see how things go, but preliminarily, well, what can i say?

i still have to sort the opto sensor for tuning (looking for one in the wanted section), but i just wanted to let you two know how delighted and grateful i am for your assistance! should our paths ever cross, the pints are on me!

i am happy to consider this matter closed (better not jinx myself)! let's see how the weekend goes...

😁

regards, 

Jeff

Thanks for the feedback.  Very pleased to hear that it all worked out well for you.  Now you have the BM8000 working, all of your other units will be put to one side.

Have fun and it is satisfying to know that I was able to help.  That beer sounds good but it will be fairly expensive by the time that we meet!!

Regards

Geoff

...nearly 1 week into the fix and everything is still perfect!

I know this thread is so 2009, but I wanted to report in that this fixed (so far) a big problem with my BM8000. The wires went in pretty cleanly, and it looks no worse than some other "factory" circuit modifications I've seen!

Thank you, Peter and geearr, for the circuit information. And thank you, burantek, for pointing me to this thread.
