I'm immensely disappointed that this thread has been up this long without mentioning the clipping characteristics of $5 diodes.

No, the burst box is supposed to have a copper coil, not just a copper ground bus wire.

Klaus does seem to get overloaded and can be slow to answer emails, but I promise he is around and will always take care of you eventually. Also Klaus has an open order for more Nobelium PCBs which I will be shipping out this week.

Yeah Musikding uses hand-drilled enclosures, they don't have a CNC machine to do the milled slots like Tayda.

You are in the wrong thread my dude. This is Robert's workbench thread, you need the "What's on *YOUR* workbench?" thread.

That hasn't been my experience, but I have no problem admitting there are better options out there. The main appeal of the 555 design is simplicity, it's not incredibly sensitive to layout, and the parts are dirt cheap. Better supplies can be made with $10-20 of parts, but a perfectly usable...

Alright so again the short answer is that you will need less filtering when powering a preamp from a nixie supply because a nixie supply has much less noise/ripple than a rectified AC supply. Honestly in most cases you can get away with just a single 10uF bulk cap and call it good. It's never a...

That's a serious question that deserves a serious answer, so I'll wait until I'm in front of a computer instead of on my phone at the National Aquarium. Short answer: you don't need as much filtering. Long answer will be longer.

Looks like there are some mistakes on the BOM, I'll need to go over that. I'm out of town for the next week or so but I'll see if I can find some time.

Klaus at Musikding is a good dude, but he seems to fall behind on emails sometimes (I can relate). It would definitely move faster if potential customers reached out to him and expressed interest though.

Everything is listed as out of stock as ordering is closed until I get back from the Baltimore Pedal Show. Come say hi if you're in the area June 13.

If your XLR output is working, the voltage isn't going to be the problem. A picture is worth a thousand words, especially in debugging, can we see your build? I'm also obligated to ask what power supply you're using, and if the tubes you have in there are new or known-good tubes or if there's a...

I haven't, I've always just used J201 there, but there is no reason a high-voltage FET wouldn't work if you give it the volts it needs. Something like LND150 could be interesting there, I use those occasionally when I just need one more stage for a buffer or boost on an otherwise all-tube...

Looks like I forgot to update stock levels on King Nothing and Particle Accelerator, I actually have plenty of stock of both. Just updated those. You need to be careful with high voltage whether it's inside a box or on a breadboard, but there's no reason you can't breadboard high voltage...

It looks like the 12AX7 prototype board was intended more for breadboarding than for actual building into a box, thus the lack of mounting holes. Maybe if you ask @Robert really nicely he could make a compact one with mounting holes for building into boxes, because the lazy idiot running C2C...

Sure, that should work.

Tube preamp into a power amp is a pretty common use case for my pedals. Just saying. I'm obviously biased here as I make money from selling these things, but hearing someone say they don't want a tube preamp makes me sad.

I just want to say that as a PCB designer I frequently hide my vias underneath components, mostly because I think it looks cleaner, but I admittedly also think about how much more fun it will be when someone tries to trace it. If it looks like something doesn't connect anywhere though, try a...

I have never heard anyone say this before.

RADJ goes in parallel with the other resistor to set the high voltage of the circuit. This is optional because the original preamp that Tungsten is based on runs with a voltage rail of about 240V, and if you leave off RADJ then your high voltage will be somewhere around 235V. If you put a 1kΩ...
