excellent advice - too bad I am learning this the hard way, as usual.

Also per Doc's comment - I now have the power amp and preamp plugged in to the appropriate circuits, so that the delay times in the power unit power things up and down in the appropriate order.

Now I just have to try to locate a replacement ribbon for the RAAL, Only available from Serbia unfortunately :)

Yeah, that could definitely cause an issue.

Did you ask Solen if they have replacement ribbons? I know have sold RAALs in the past.

Thanks for the suggestion. I'll check. Unfortunately, the 70-20xr is an OEM only product so usually only manufacturers get them and so Madisound and others don't carry parts.  I was able to get them because I was finishing a speaker project that Roy Johnson started before his death last year. So Aleks was willing to help me out.  Still can't believe I smoked it, I guess you guys have seen a lot of smoke over the years though.

Drew, I know Madisound doesn’t carry that model, but a call or email to Adam Johnson couldn’t hurt. He has gotten me stuff that no one else could, so a reach out to him might pay off. If you are interested PM me for his email. The great thing about the guys at Madisound is that they service the DIYer with the same care as given to the OEMs.

Doc -  You are the MAN!  Solen had them but don't put anything about the parts on the website.  Got some ordered and sent Fed Ex.  I think all problems are fixed so maybe I can get back to listening.  Not going to mess with anything for a while.

The folks at Solen are super nice and very prompt in communicating and shipping.

They sure know who you are Doc!

If anyone is interested, attached is a photo showing what happens when you fry a ribbon.

Some duct tape will fix that right up. My scare moment with the RAALs was when a new employee was putting one of the foam diffusors on the tweeter. There was a little piece of steel wire stuck into the foam, that is attracted to the tweeter magnet to hold the foam in place on the tweeter flange. He inadvertently brought the foam up to the face of the tweeter at a right angle and the magnet pulled the wire right out of the foam. It shot into the ribbon opening and grazed one side of the ribbon. Another millimeter over and it would have punched right through it.
