Hey Guys
Never mind
Thanks

Hey Y'alls
Where should I attach the POS lead for a battery on this 'ole thing?
Thanks
Jeff

Hey Guys and Gals
Voltages are all good on the big board but when I attach the daughter board, the overload LED just flashes. Made a mistake and reversed + and - on the DC jack at first, so I rebuilt the entire power supply. Even the 2N5088, but the LED is still flashing in the off position, and lights in a strained intermittent way in the on position. Any thoughts are appreciated.
Thanks
Jeff

Hey Ya'lls
This is my first attempt, simple text (converted for printing) on a white BB enclosure. I thought the size was all done to scale, but they keep rejecting it (wrong size). Can someone help?
Thanks in advance
Jeff

Hey Ya'lls
I'm getting signal into that "stress" LED, but no sound when blend is all the way delay...getting some analog noise (normal amount) when engaged. The beginnings of my problems start at IC3 pins 1, 2, and 3. 1 and 2 are somewhere north of 14v and 3 is jumping around. 4 is zero, 5, 6, and 7 are at 7.5, and 8 is 15.07...the A side of IC3. Any and all ideas are appreciated.
Thanks

Hey folks,
I installed C35 (100uf) backwards and it blew up. Replaced it, and all voltages seem ok (I think) but not getting any output from pin1 on IC1, or IC 2, pin6 and 7 and, usually when you plug the pedal in, you get a flash from the "overdrive" LED, but now, nothing. Also replace C36 and C37...same results.
Thanks!

I have a file that used to get accepted at https://jlcpcb.com/ but now gets rejected with "no border" as the reason. Anyone want to take a stab? I'll compensate with paypal, parts, your pleasure. It's a small clone circuit with 3 depth selections.

Thank you!

Great board, Love it! Sounds killer.

Greetings.

Can't seem to find the value of R29 (it was an addition back in the day). Any help is appreciate.

Love the pedal, thanks skyled and fair.child for the help  Had to adapt the B2M pot using bus wire.

Been a while since I was in the game, but apparently I'm back now due to a request from Greece a few months ago, but I digress. Anyone know where i can find a replacement tape for an ep-2 echoplex? Probably need a belt too.

thanks much
Jeff

Hey Guys,

I've had volume drop in a tonepad build, and guitarpcb build. Can I compensate with a resistor value? 2nd Question; Will lower gain transistors reduce distortion? Using MPS18's, thinking of 2n3907's...

Thanks

2nd of 3. Got it all wired and got the bulb lit, put the thing down, and all went dead. Before I panicked, I checked the power supply (brand new OEM Jim Dunlop 24v AC 200ma) and bam. It's dead. Either I shorted it somehow, or it sucked. Gotta order more. Going with Electro Harmonix 18v DC center tip positive (I'll wire the jack in reverse) this time.
I'm going to file down the bottom of the board, use a compressed air can to blow out the dust, and reinforce the electrical tape at the bottom. Dammit. The bottom of the board was hitting metal from the stompswitch, as I didn't insulate there...wonder if that shorted the PS....either way, I DID HAVE BULB! Almost there.

Yes, I know. WTF is up with all the "glory holes"? This started as a magnus modulus enclosure and worked its way through dipthonizer (on the orig style huge boards) to whatever. Now that we've got that out of the way, this thing sounds so awesome, it will NEVER leave my pedalboard. Brian, what are your tweaks vs the neo? Whatever it is, YES!!! Thanks Madbean for being Madbean.

Title says it all. I tried a different charge pump (LT1054) both new, same result. There doesn't seem to be any solder bridges, as I inspect under magnified lamp, but my eyesight is suspect. Thanks in advance.


Jeff

Yo Brian,
Are 2N5088's or 2N5089's suitable replacements for the BC549C's? Is the switch an ON-ON, and, got a photo or wiring diagram for the switch?

thanks as always,
Jeff

Just one main problem at the moment. The lamp has never seen orange glow. LFO is working nicely as the LED pulses in time. Volume and Speed work nicely as well. I'm using a 24v DC power source, positive center, so I wired pos/neg backwards on the dc input. I do have the diodes in the "AC" section, but that shouldn't affect anything, should it?

Thanks in advance
Jeff
