non responsive -new Quickie/PJCCS [solved]

[xcoolhandx]

I need some assistance with my new Quickie bottleheads ,I received the kit few days ago and just finished building it,I took my time building it but my latest creation is dead silent ,
here are some voltage measurements and some pics ,any idea ?

What were the voltages before you put in the PJCCS?

Additionally, have you tried other D-cells?

 

[xcoolhandx]

I didn't check voltage before  PJCCS ,I was little tired and want it to get this done ,also skipped on  4.02KM resistors since you supposed to cut them off any way
Should I disconnect PJCCS and check voltages again ??2

EDIT; I should mention that I also used some third party hookup wire to connect RCA inputs to the switch  and used solid core "twisted" (solid) wire for PJCCS

I was trying to ascertain if the unit worked pre-upgrade. The filament voltage isn't making it from the battery to the switch on both sides, so it's probably bad or backwards batteries.

It is kind of difficult for us to give efficient tech support when builders deviate from what we have set up as an assembly schedule. My suggestion is to come back to troubleshoot the preamp after you are rested. Check the batteries first as Josh suggests. If that does not turn out to be the problem, remove the PJCCS and complete the basic kit as the manual describes. Then do your resistance and voltage checks, and if they come out correct give the preamp a listen. If they don't, we will be able to walk you through the things to check to get the preamp running and then you can install the PJCCS. Then if the PJCCS installation doesn't work you will have a lot less circuit to have to work through to find the problem because you know the basic circuit works fine.

here it is ,no PJCCS

What resistance do you measure at terminals 4 and 9?

What resistance do you measure at terminals 4 and 9?

terminal 4/9=.0.23~0.32 M ohm

off/no batteries /tubes in ,measured with Fluke110 (auto range /omh )

 

[Doc B]

Check to make sure you have a 1.07k ohm resistor between 4u and 5u, and another one between 9u and 10u.

 

[xcoolhandx]

I have them both

Edit ; should I  re-soldier all four resistors and caps  ?

 

[Doc B]

If you look at the resistance measurements in the manual you will see that 4 and 9 should each read 1.07K ohms, the exact value of the resistor that goes between 4 and 5 and between 9 and 10. So if you are reading a very high value there and the voltages are not right there are three possibilities:

1) the resistors are the wrong value. You can try measuring the resistance right across the resistor leads, from pin 4 to pin 5. If it does not read 1.07K or close to that the resistors may not be the right ones.

2) the resistors are not connected. If the resistor reads 1.07K but the resistance between 4 and 5 reads a really high value the resistor must not be attached well enough to conduct.

3) The resistors are connected at both ends, but wired to the wrong terminals. A visual inspection is the easy way to double check that.

 

[xcoolhandx]

both of them are 473 omh

[Doc B]

Those are 475K ohms. Sounds like those are the resistors that should be connected across the RCA output jacks, and that you may have the 1.07Ks installed on those jacks instead of at terminals 4 and 5.

 

[xcoolhandx]

yeap , ...I should check them before installation -both look very similar ,it's all my fault

 

[Doc B]

We all make mistakes. That's a part of the process. Luckily the terminals are close enough together that you probably have enough lead length left on each resistor to fit in the proper location. Judging by your measurements a resistor swap ought to get things running right.

Thanks you Sir ,voltages were spot on  so I installed PJCCS and I'm loving it

 

[Doc B]

Great job! Looks stunning.
