Hi there:

Wow!  I'm so glad that I found this site. I'm not quite ready to start building my own SS amp, but I'm trying to save the old ones!  I have a primo Kustom SS 150 combo and the mysterious Baldwin Professional 2 x 12 Professional Custom with the rare Supersound! (In near-perfect shape I may add ... Wotta sound!  WOW!!)

Anyway, I have a new Baldwin mid '60s SS head on the way.  Off ebay and it supposedly works.  100 watts instead of the Baldwin' Pro Combo's 45 watts.  Might be an early Baldwin SS Exterminator top, if you guys are faimilar with the oldies.  Not sure until I see it, but I am psyched to try it out, hoping that it sounds like the point-to-point wired Professional Custom that I have now. 

But here's the prob:  How do I find or figure out the ohms rating for a speaker cabinet to use with it?  The Baldwin SS Professional 2 x 12 combo has two 4-ohm speakers wired in parallel for 2 ohms  (I think), but that doesn't mean that this one wants 2 ohms.

What can I use and not use? 

How can I find out what would be the optimal ohms for a cab for this head? 

Is there some way I can measure the output and get the correct resistance that way? 

Could a pro place like Orance County Speaker Repair somehow test the output and give me the best ohms rating for a cab? 

Thanks for any help you can give.  It's going to drive me crazy to have that head sitting here, being too afraid of blowing it up by plugging it into the kustom speakers or may be the speakers on a Deville tubed 4 x 10.

Thanks,

Irv Dierdorff
