newb - BYOC Tremolo debugging

[markm]

sorry, but I never blindly trust schematics that serially connect 2  0.68µF NP caps in a phaseshift LFO without a resistor to ground,

or un-designated LED current limiting resistors or input caps,

while having to fish out,

which of 3 PCBs fit to the schem.

But that`s just me.
And my honest opinion.

Agreed.
If I recall correctly, there is an error in this schem.
I tried to Build My Own Clone from that schem and it failed miserably. I think it's missing a couple resistors but, I can't remember.
Must be an "age" thing!

I totally agree. You'll notice that my comment mentioned the proprietor of BYOC, not the DIYer at all. Read it again. And there was no blame in it. I was just opining that the proprietor should be handling their business.

Seems I misunderstood you there, it already sounded un-RG-like to not offer constructive help to a DIY-er

The PCB has a 15k resistor to ground from the first .68uF cap in the LFO circuit. I noticed the schematic had a missing resistor a few nights ago when I was tracing through the circuit.

That's right.....I knew there was something missing in the schem.

The schematic is freely available in the kit instructions.

I'm sorry, they did not have one for their Phaser kit. My bad.

Alright here's the readings

Q1: 2n5457
D = 9.74
G = 9.23
S = 9.74

Q2: 2n5088
C = 9.72
B = 9.61
E = 9.72

Q3: 2n5457
D = 9.73
G = 8.82
S = 9.72

Q4: 2n5088
C = 9.73
B = 9.71
E = 9.29

D1: (LED)
anode = fluctuates between .003 and .113
cathode = 9.29
