Subject description: Sound problems with blofeld, of fix doesn't work for me.
Reply with quote  Mark this post and the followings unread

Hey All! I've had a blofeld for a while and I really love it. I recently unplugged it and was considering posting on eBay.

I had a change of heart and decided to keep it but when I plugged it back in I got absolutely no audio from any of the outs, although if the headphones are in I do hear a pop when I power on, so presumably all the outs are receiving some signal.

Anyhow I was relieved to see the fix oft discussed but when I went to make the repair I found that I do not have the same pcb as is photographed in various "replace the 6.8ohm resistor" fixes.

My board seems to have a different layout. It says BFMB V2.03

Has anyone done this fix on this board or know anything about this problem?

It would make me sad to have to sell the blofeld for parts (cheap:() on eBay.

Is this my punishment for thinking of selling it in the first place?

Any help would be appreciated.
Thanks!

I opened my blofeld and couldn't find the resistor.
This post has an image of where is located http://www.stereoping.com/waldorf-blofeld-reparatur-toter-audio-output/?lang=en

but the problem is that in the photo it says on the board rev 1.something
and my board is different is v2 and the resistor is not located as the image.

Can somebody help me to locate the resistor in the v2 board?
