Build Reports / Re: Lil' Green Watter!
Last post by Valleyslad - April 16, 2024, 11:37:23 AMJust came across this little amp, whilst looking at the tube cricket. To my ear this one sounds better. Does anyone have a vero layout or better still a gerber they'd be willing to share?

Build Reports / Re: Hamlet + Delay with mods
Last post by jessenator - April 16, 2024, 05:27:57 AMThat's neat. Always interested to try new PT2399 circuits, so I'll add this one to the list of breadboard projects.

VFE Projects / Re: sps switching board questi...
Last post by Aentons - April 16, 2024, 03:00:14 AMHmm, I don't see anything referencing 15v or 18v versions. Where are you seeing that?
As far as I can tell there are two versions of the SPS switching boards.
1) Truesoft SPS - this is mostly thru hole components with 2-3 smd ics on the back.
2) SPS System - this has mostly smd components and was designed for mass production. I think he only sold these fully assembled
You want the Truesoft SPS pdf in the assembly folder

VFE Projects / sps switching board questions
Last post by Ash - April 16, 2024, 12:30:04 AMAny one else having trouble sorting out the sps switching board options? I purchased the files from vfe and got many of the boards and was going to start assembling some of them. The circuit pcbs are pretty clear but when I started looking at the sps switching board it all gets fuzzy. In the files there is an SPS system board, a truesoft sps 15v board, a truesoft sps 18v board, a truesoft sps through hole board and a truesoft sps board. How the crap am I supposed to know which one to use for what? In the assembly documentation it has sps v2 assembly. It matches the 15v and 18v board but only shows one side but doesn't show the back side. No where else does it show what should go in those spots. A few are easy but a few would just be a guess, lol. The truesoft sps documentation shows yet another board with different parts and then there is a spreadsheet for an smd version that once again used another set of parts. I just wondered if anyone has come across any clear cut directions on what to use when and where with these? I really want to get some of these going but a the moment I am kinda throwing up my hands. I don't mind a little pic programing or smd soldering but this is a bit wonky, lol.

Last post by jessenator - April 15, 2024, 11:45:14 PMThat's horrifying...
Y'know, now you mention it, on the only two flights I was on in 2023 I didn't notice a single barf bag. Like, how rare is WAX and PAPER and maybe some WIRE to cause supply chain issues for barg bags?

Open Discussion / Re: Just Saying -- the soapbox...
Last post by lars - April 15, 2024, 09:01:31 PMI know this thread is old, but I prefer to use what is established, rather than start a million new threads covering the same thing.
Soapbox time:
Have you ever been on an airline that didn't have ANY barf bags? I was on one last night. And of course, they hit some really bad turbulence, the kind that has those wonderful free-fall drops mixed in. And yep, people started puking. But there were no bags anywhere. And since it's "company policy" that everybody (including flight attendants) have to stay where they are during turbulence, that means nobody could go to the bathroom, nobody could get any assistance, nobody could do anything about puke flying all over. By the time the plane landed, the aisles looked like a crime scene of spent napkins and piles of digested pretzels.
I'm wondering...who is the absolute bungling idiot that refused to put barf bags on the plane? What did they expect would happen when the puke starts flowing? Does somebody hate the poor souls who have to clean the planes? Yet another example of the crippling stupidity so prevalent in the world today.

Build Reports / Hamlet + Delay with mods
Last post by Aleph Null - April 15, 2024, 06:07:22 PMI built this stock and found it to be a little noisy with my rig. This isn't a criticism per se—my amp is particularly sensitive to noise and PT2399s aren't known for their fidelity.
I received the enclosure as a Christmas gift and wanted to show off as much of it as possible. Label maker labels are encased in clear coat.
The output volume was mounted internally. The "tails" switch grounds lug 2 of the "Repeats" (or Regen) control by connecting it to lug 6 of the bypass footswitch. This grounds the output of the PT2399 when the "tails" switch is activated and the effect is bypassed.
Above is the original schematic with my values in red. R2 and R4 were changed because that's the closest value I had on hand. R3 and R13 were changed to increase the dry and delay output. Unity volume can then be achieved with a lower "Output" setting, which attenuates the noise from the PT2399 and the rate LEDs. C14 and C15 were upped to reduce the hiss in the repeats. They still have that bright bell-like quality that's the signature of this circuit, but there's no burst of white noise that you get at higher delay settings with the stock values.
On the whole, I'd recommend this circuit. I don't think most people would hear the increase in noise floor with most setups.

Open Discussion / Susan Tedeschi's OD
Last post by TNblueshawk - April 14, 2024, 12:35:17 PMSo what we have below is her OD that my guitar tech neighbor ( he is Derek's and Susan's guitar tech) gave me to fix a few things on. To say I'm nervous to not screw it up in some way would be an understatement. It's got a jacked up battery cable that was "hot wired" 10 min before a show as it putzed out. The 9v jack took a Mike Tyson in his prime blow and punched it in which I assume someone stepped on it sideways or something fell on it. The more invasive thing is pulling the Vol pot B100k and replacing it. It works but where the solid shaft meets then knurled part you can actually open it up a bit. There is a lot of play. I would guess that when it was on its side and took the blow the Vol know got bent as well creating this plan in the shaft. I have since decided though since he says she has not had any issues with the pot to just leave it along.
Anyone familiar with Moollon from South Korea? I did some research. Interesting stuff on them. It is clear they really don't want anyone poking around at their PCB.
