So there are 3 that say 9v?
@Sushi Box FX
The PA is interesting (I have the Mini-tube version). I don't really get much dirt from mine, I like it for the fat thickness. The hum is interesting because with mine I've found that if any of my basses have any type of extra noise...such as EFI buzz....the PA makes it 10 times worse. No other pedal does this, not even the Slampegg so it's kinda weird. But if I play a bass that has no buzz, the PA has no buzz. Due to that, I don't think I'll be able to use the PA in a live situation but that's fine as before I discovered the buzz I found I much preferred the PA for my home/direct board and the Slampegg for my 'goes into an amp' board.
Oh right, the ones in the raw finish or other colors, which were files I made for the first time in March, got changed over to 9V. The full color artwork, which I made for the prototype and hadn't changed, is the one with the mistake. So I think that means 3 raw finish, 1 rainbow's end finish, and 1 unfinished (at the customer's request) do not have the 12V label, so 8 have the mistake.
I'm wondering if we might be having the same/similar problem. I just got my Westinghouse plugged in and noticed a squeal as well, that changes frequency when I turn the Volt knob. Even stranger, if I tap on the footswitch even lightly, it sounds like I'm tapping on a spring. Audio attached below... You'll hear the clean signal before the WH is turned on, and then the frequency change as I slowly turn the volt knob up from minimum. The squeal disappears around 2:00. Then you'll hear a quick whoosh as I turn Volt to max, followed by the sound of me tapping on the footswitch.
I've got the WH powered with my 1-Spot daisy chain power supply, but the Westie is the only thing plugged in and not on a board. I'm using the exact same setup as I used for the Edison (and my Slampegg Mini, and other pedals) without trouble. I've done some trouble shooting to eliminate other issues. Our house doesn't have a grounding issue, and my bass wasn't even plugged in for the audio sample... it's very clearly coming from the WH.
Also, I know the Edison was subtle, but there's still a noticeable difference between on and off. I did try it with a bass (and audio loop), but I'm not hearing a difference with the WH on/off, and the Volt knob just changes the frequency of the noise... Maybe the EF86 in mine is microphonic? (I've never experienced a microphonic tube to know what it really does, and I don't have another EF86 to test with.)

Not in your head. I have heard that. For me I noticed it when I have run the PAX and the Deep Dish together. But I haven't had that whine with either alone. Haven't built them into a board yet so I’m interested to see what’s up.
Nailed the sound. That's what I'm getting too. No spring sound. That may be a microphonic tube and or one that's gone bad.I'm wondering if we might be having the same/similar problem.

I came here to write the same thing. Tapping on the box there's a noticeable spring sound as well, worse than other tube pedals I have. I'm using a Cioks 4 and have tried using different psu and there's no difference. I can tell the WH is on or off, there's a definite thickness it adds. It's slightly different than the Edison, more mid focused and tighter. The Edison is looser and more pillowy down low, less defined, but I might like it better for a more tucked back quality.I'm wondering if we might be having the same/similar problem.

I've attached my sound sample, there's tapping on the box at the beginning, I turn down the voltage knob, turn up the volume on my interface, then turn the voltage knob back up. The squeal stops for me around 2 oclock (or goes out of my hearing range
)

Playing around with both more, I can absolutely hear and feel a difference with the WH voltage knob. Back it off to around 2:30 or 2 o'clock makes the lows sit a little more, it feels like the bottom opens up but stays real punchy and tight

Sorry it took me a bit to get back to everyone, the weekends are always busier than I plan on them being.
The squealing that changes frequency with the voltage increase is interesting though, I wouldn't expect that to be related to microphonics, though I guess I could see how it could be? The high voltage is generated by a switch-mode power supply, which means the switching frequency is directly related to the output voltage. Even at the lowest voltage (35-ish volts) the switching frequency should be well above hearing range, but to a more sensitive microphonic tube it's possible that it's picking up some harmonics from the power supply's oscillator. I'll get a new tube out to you and see if that takes care of the squeal as well.
I apologize for also not catching these before they went out the door, I was a mess by the end of the month and let my anxiety get the better of me and it appears I sacrificed quality control for speed, which I have been specifically (and repeatedly) told not to do. I will do everything I can to be better.
I'm wondering now if I should start using modern production EF86 instead of the Soviet 6J32P. They're about 6x more expensive, but if the Soviet ones are going to give consistent problems it may end up being worth it in the long run. I'll pick a couple this month in my big JJ/Tesla order and do some tests.
That most definitely sounds like a microphonic tube. When I first talked to a friend about doing something along the vein of Edison he mentioned that he tried an Edison and had a microphonic tube and found that EF86 were much more likely than 12AX7 to go microphonic. I didn't notice anything that stuck out as microphonics during testing, but I also don't usually test at high volumes. I'll start ordering more EF86 than I need so I can go through them and test for microphonics in the hopes of preventing anyone receiving a bad one. Give me a couple days to go through the EF86 stock I have on hand and I'll find some that are not microphonic so I can send you a replacement.I'm wondering if we might be having the same/similar problem.

This is an interesting one, the only possible explanation I can think of for that would be of harmonics from the oscillator stacking when both pedals are on together, making them louder? It sounds a little farfetched to me, but I admittedly don't have any other explanation.
Also definitely sounds like a microphonic tube, same situation as 5sg, I'll get you a new tube when I've had a chance to check through my stock to make sure I'm not just replacing microphonic tubes with more microphonic tubes.I came here to write the same thing.

I finally plugged the WH in. I’m getting a horrendous squeal from fully CCW all the way to roughly 2-3 o’clock. If I crank it, it sounds good though.
Hi everyone.
here is the first video I promised with the slampegg using different tubes.
first, please pardon the hiss of the interface. My good interface is at the office, so I’m stuck with a lame one for now. oh, and my awful playing. My gear is better than me....
Chain- fender 62 reissue with TI flats (15% off tone)> slampegg > cabzone x with b-15 IR > tascam interface >iPad.

I ordered a raw enclosure so maybe mine will say 9v but I’ll have to wonder about the squealing a little longer as delivery has been delayed.
Is the tube user replaceable?

I can’t get to it again until later. I’ll do a little more investigating and let you know.
Yeah...I’m afraid I’m getting the metallic PING with my Particle Accelerator, too. Also a loud click when I stomp it. I absolutely love it otherwise. It’s the original(?) version from last year.
So I've been doing a little more reading about EF86, and apparently microphonics are common, to the point that some builders buy a batch of 50 and end up throwing half of them away for noise/microphonics. I didn't realize I needed to be so selective with the tubes, but I will be ordering a handful of TAD EF86 this month that have been "hand selected for low noise and microphonics." I have another 20 or so 6J32P coming so hopefully I can test all of them and find enough that aren't microphonics to take care of March and also get replacements for the microphonic tubes in March batch.
Unfortunately also common, that was one of the biggest factors for me to stop using them. If it bothers you I could try replacing the tube for you, I still have a handful (literally like 4) left, though I unfortunately can't guarantee that these won't go microphonic.
