Dreamy Creamer debug help

Ok well guys just forget it instead of being blastered just because I happen to have lost my DMM I'll just stay quiet.

Thanks for those who helped.

Dude look. Without a DMM there's very little anyone can do for you. That's just a basic tool you need for debugging electronics. It's like trying to work on your car without a wrench, or build a house without a hammer. You will only be able to go so far.

Sometimes they go on sale for even less.  Good to have a few one in the car or truck and one in the house.  You might not want to leave a fluke DMM etc in the car.

  Yupp...I get 'em for 3.88 at Marcs Discount stores, best deal ever on anything AFAICT.
  Just set it aside until you can aquire the absolutely necessary tool...

I tried to build a (close to) CD spec'ed Muff once and had the same problem. But I, having a DMM, was able to check the transistor bias. It went something like this:

Q1: ~4.5V
Q2: ~4.5V
Q3: ~4.5V
Q4: ~0.7V 

After triple checking that everything was the correct value and that there were no bad solder joints I did the math and this did make sense. Maybe it was because I was using BC239s instead, but the 390 emitter resistor was just way too low. I replaced it with a 3.3K I think and it ended up working fine. Then again since 390 is in the schematic and I'm sure tons of people have built this successfully I may be compensating for a different error I made.
