Are these interchangeable in this Klon clone? I'm building the Kliche mini and it calls for the TC1044SPCA but I only have access to a MAX1044CPA. Just wanted to make sure it will work before using it. thanks

Building the closed circuit limiter/booster. I don't have any BAT42 diodes. I have BAT41s and 1N34s on hand. Does anyone smarter than me know if they would be a suitable replacement in this circuit, or any other diodes? Or should I try to hunt down some BAT42s if they are key to the...

This helped me so much. Added the jumpers and it works great now! Thanks for saving my board!

I screwed up and soldered the first dpdt switch of the three effects (centre chorus on/off switch) on the wrong side of the board. I was able to remove it and reinstall but pulled off a few pads in the process. So I’m going to need to bridge some connections from components before, to and after...

They do have 5528s! I’ll start with that and see how it works, thanks for your input.

Howdy, I ordered the Pitch Witch and the Pendulum Tremolo PCBs. The Pendulum calls for GL5516 LDRs and the Pitch Witch for a “1M LDR”. I’m new to LDRs, how do they differ and labelled? This is what my local shop carries for LDRs. Will any of them work for these two pedals? They mark them as a...

Ok thanks. I guess I’m having a hard time understanding the schematic and which component goes into the next. Q2 collector is loud, R3 is loud, but C5 is quiet. It looks like C5 is next in the path before going into the eq section. I reflowed the solder on C5 but didn’t fix the problem. I’ll...

Ok looking at the components in the EQ section after Q2 going into Q3, R7 is super quiet, R10 is about level with input but is distorted, R8 and R9 are super quiet like R7 (barely audible). R3 is loud and matches the collector of Q2. C5 is quiet. Is there anywhere specifically I should check?

Actually I can hear the signal on Q3 base but it’s REAL quiet.

Haha I like that! So probing the audio signal, everything seems okay until Q3. Collector of Q2 is louder and more distorted than the input jack signal. But then when I probe base of Q3 there is no audible audio signal, it just pops when I touch it.. Then Q3 collector has audio signal but it’s...

I cleaned the pcb with alcohol and a toothbrush. Didn’t fix anything unfortunately as you suspected but it’s easier to see now. Posted some more pics above, if perhaps something looks suspicious. I can’t test the audio signal at 4V right now because I was getting the 4V with Q1 transistor...

Here’s the meter I use. Unfortunately what you pointed out was just a little piece of metal flake or something on the pcb and wasn’t affecting anything. Brushed it off and nothing changed. I’ll try the toothbrush and achohol suggestion tomorrow!

Hi Coda, I am reading 17.75 volts in the circuit at the vcc spots so I think it’s working okay?

I checked the continuity and resistance of everything this afternoon. I went through each resistor and every one is the correct value/resistance it’s supposed to be, as well as the circuit has continuity where it’s supposed to. I plugged in the pedal again and jammed a little bit and it does...

Checking further resistance; Q1 collector connects to Q2 base. That’s what it should do. But when I check Q2 collector to Q3 base it shows -11 on the meter. What is negative resistance? So it is connected but there is some resistance? Is that would it should be? It’s also showing -13 and -10 on...

I was really hoping it was the sockets that were the problem but I just removed the plastic socket housing and soldered the transistors directly to the socket pins and get the same result Q1 2.2,1.6,1.03 :( I even continuity tested the transistor legs and the socket pins/legs and they’re...

The component tester I ordered arrived today and I just tested the three transistors. They range from 311 hfe to 429 hfe. From what I understand hfe is how much gain they have. What does the Uf voltage mean? What do I look for when using this machine? Is it more to tell me if a transistor or...

https://www.taydaelectronics.com/3-pin-2-54-mm-single-row-female-pin-header.html Tayda doesn’t seem to carry the same part number I ordered (X-7260) but they look identical to the ones in the link. I just checked and there is no continuity between the pins.
