Thanks. I’ll try out what I have. I can always order your suggested transistor next time I do a mouser order. It’s in my cart waiting. Thanks for the input!

Thanks for this. I might have to get one. I have a 2n2905a lying around that is a pnp silicon transistor. Do you think that would work?

The problem is that you need an mn3007. The building documentation says that it will work with a 3207 but it doesn’t. I’m not an expert but I had the same problem as you and had t was fixed by using the 3007. Many people on the facebook group had this gap poo en too, it’s a common issue. Save...

Thanks for your reply. As this is the simplest option it is also my preferred option! I figured this would work but I just wanted other opinions. I’ll try out the trim pots if necessary.

Hey everyone I'm thinking of making a Simulcast/Duocast but I don't have any germanium transistors and I have a couple of quesitons: Can I use a PNP silicon transistor in place of the germanium one? If no to above, can I modify the PCB to accept NPN transistors in q2? Schematic is here I've...

RE the compensating cap for IC3. Do you mean I should connect Pin 1 to ground? Would a 100uf electro cap do the trick? It does pop when I flick the switch and it takes a while to change voltage. I did put this together but it clearly isn't working as I had hoped. I might make a version 2 that...

Haha well that will do it. Thanks again for your comments, they are a big help. I might revise this design to be a lot more simple. Don;'t get me wrong, i'm not trying to be rude. I really appreciate the help.

Thanks chuck for entertaining my stupid ideas! Your feedback is appreciated. I’ll try these out today and over the weekend. R28 is 7k5. Why will the buffer switch kill the signal in the non buffer position? Is it because the power supply is cut off in the non buffer position? You are right by...

Hello again. I finally got around to putting this together and (as I had suspected) it doesn't work properly. Would anyone be able to have a look at the schematic for me and give me some tips re why why it's not working? The most recent schematic is attached. It passes signal so that's a win...

One thing that stands out to me is the gain and band clips are connected to Vref and not ground. I took this idea from the stockade but other TS schematcs have this connected to ground. Should this matter?

Hey I've been working on a Tube Screamer circuit with all of the mods. I posted about it on this thread but I have clearly bitten off more than I can chew. I have put it together and it passes signal so that's a win, however there is no gain. With an audio probe I have tracked the problem to...

I got this thing going properly! Apparently if you put the led in the right way it works as intended. Who knew? D6 on the schematic is a rate LED. Didn't know that since I'm pretty sure the original didnt have one. Pretty neat. I'll put this in a box with my next order and hope the noise goes...

Hi everyone. I’m hoping to make a gonkulator but I need to find an mc1496. I see a few on eBay but I have been burned before. If anyone knows a reputable seller with this that would be awesome. Preferably through home but smd is ok. I see banzai has it but it’s about $50 shipping to...

Yeah the internal trim is a bit of a waste for me. I just have it fully on. Full clockwise (for mine anyway) has max sag. You can actually see the boom LED light up/decrease when you turn it. On my build there is a huge difference in the weight switch with heavy being very saggy and light being...

Well I put this together this afternoon. I won't say it went smoothly but it seems to work. Here is a video. It's very noisy and I'm not sure it works 100%, but it works and sounds pretty much like it should! I'll have to keep working on this.

Mine seems to be working fine. Yellow led is always on for me too. If the red led goes on but doesn’t impact your round I’d look at r22. You may have the wrong value here. I put a trimmer here and found that there was a narrow area that it actually worked. I settled on 1k5 anyway Or you could...

Have you checked every single item in your white layer? Not as a group? I find that I often make a fill in rdg white but the stroke stays in another colour especially is you select everything in a layer/group and change the colour at once. You kind of have to check the fill and stone for...

Why not try a trim pot with pins 2 and 3 connected? I do this a lot when I can’t decide what I like best. Just put a 100k trim where your 100k resistor is and adjust to see what you like best. Or a lower value if you don’t like what you have.

🥸 Well I’ve done the layout already. I’ll double check the schematic tonight (I’m always making silly mistakes) and send it to JLPCB. I’ll let you know if I get it working. If you don’t hear from me then it’s in my drawer of shame.
