At the end of my rope..need some advice

[taco]

Tested, and here are the results..
Q1=16.1V
Q2=15.5V
Q3=16.5V
Q4=16.9V
Q5=.3V ??
Q6=19.0V

So, are Q4 and Q5 working in conjunction with only leg Q4 working and Q5 dead? That would be too easy?.

Those were all... pin 3 voltages??

Q5 doesn't normally do anything, it's intended as a current limit trigger I think.

None of the voltages seem out of place.  The problem is it's not rising much above 16V though?  Even with VR1 all the way towards the R21 side?

I never adjusted VR1, but I will take the same readings with VR1 adjusted fully toward the R21 side.

Thanks

Is there a chance you have a short in the secondary of the transformer?

Ok,
Here are the results after turning VR1 completely toward R21.
Q1 - 37.8V
Q2 - 37.8V
Q3 - 38.3V
Q4 - 39.4V
Q5 - 0 leg one, .4 leg two, .3 leg three
Q6 - 38.7V

Results seem normal now? So I adjusted VR1 for an output voltage on Q1 of 32.0V
Plugged in the hand piece, and she purrs like a kitten. I haven't really put any load on it as of yet, but ran it for about ten minutes and Q1 gets warm (normal), and everything seems normal. The caps and re soldering the board must have worked, but VR1 was way out after that, but I think I tried turning the pot during testing it out of circuit, so I'm at fault there.

Thanks for everyone's help!! 
I hope to learn enough in the future to help someone else like you all did for me.

Kudos to all involved...

Ah, cool. Glad it worked.

Still doesn't fix the fundamental problems we've noted, so... try not to go hard on it, anything that causes a lot of current draw especially at low voltage (low RPM).

Thanks Tim,
Really appreciate your help.
