Quickie Upgrade [Solved]

[mkane]

Voltage readings A5  275mv
                            A6  2.8v

                            B5  1.9v
                            B6  27v  Something's amiss with A side. Seems like it should be so easy.??????????

 

[Paul Birkeland]

Is this with the PJ CCS?

 

[mkane]

It is and I think I've found the problem.White wire was connected to U2 when it's suppose to go to A2. Volts on A side are a bit high but it's better than a few mv.  No sound from A side

 

[mkane]

A6 /36.9A
B6/36V

A5/2.9V
B5/1.9v

There is just a hum, no sound?

 

[mkane]

  Those #6 pins should read 19-21V

 

[mkane]

These 4.02 resistors, in my build the yellow stripe is @ the bottom. The pic looks as though the stripe is at the top. Does this matter?

 

[kgoss]

Resistors are not directional. As long as you install yhe right one orientation does not matter

 

[mkane]

Thanks but still no love

Post photos of the board if possible.

  Anythings possible around here,

  I'm going to need a few beer's when this get sorted and I thought yesterday was stressful

 

[Paul Birkeland]

It's tough to tell, but be sure the UF4007's are oriented correctly.

Also, the PJCCS on the Quickie 1.1 won't work unless the D cell batteries are properly oriented.

  Banded leads into square pad-check.  Is battery orientation any different running without this upgrade?

  Voltage is thru the roof on A6/B6  36.9 on both sides. Spec calls for 19-21

 

[mkane]

    Nothing from side A. Bit of touch up and there's no hum, B side work's. Voltage still a bit high.

I'll take one stab here. See the solder joint 'IA' .  Hard to see from the photo, but it may need a bit more solder. I feel your frustration, as I have done a few of these and wonder how the hell I ever ended up with a problem with such a seemingly simple circuit.

 

[mkane]

  I'll give that a go after my first cup.

 

[mkane]

  Voltage readings.  1A/4.2V
                                1B/3.2V  spec's are 38v
                               
                                A6/36V
                                B6/25V    spec's are 19-21
                         
                                A5/2.8
                                B5/1.8    spec's are 2VDC                      I've gone over the build process countless times. B side plays music

I can't really make it out from the photo, but is the A side MJE350 (Q2), damaged?  Almost looks like there is piece of the case missing.

  What if I flipped this board, b to a, a to b to be sure it's the board not the quickie.  I would just remove the upgrade and see if the quickie still works but I cut the caps short that were between 1 & 2/ 5 & 6 U .
