Hello, I bought 4 boards from your store and paid for them, but you refunded me. I don't know what happened, and I asked you but you didn't reply. What exactly happened? I have already arrived at the computer case, only the PCB board is missing

I have built two of these before one with this transformer which I can't remember were it hook up and one with out. I assume I had a tap from my power transformer for this. I just don't see the separate transformer in the layout for the 102. I must be getting old and forgetful. I little help would be appreciated. Bill

Hi there! I ordered a SLO PCB last week (Thursday night, which may have been Friday morning in the UK) but haven't heard anything regarding shipping. Admittedly, it is to the US, so I imagine that complicates matters, but I've even emailed Andrea without reply.
I also noticed that he had posted on Reddit yesterday but somehow his account got banned, which is confusing since I can see deleted posts (I have moderator tools at my disposal) and see absolutely no reason to have banned his account from the whole platform.
So, I'm just wondering if everything is alright over there in London.
Hi Tom!
Thanks for the purchase first of all. And yes, everything alright here, all parcels are being handed out to the courier today :)
Unfortunately I’m not sure what happened with the Reddit post: attaching the link to my webpage might have triggered the banning 🧐
Cheers from London

After many personal delays, I finally finished the Dumble 102 build! Excellent board and great experience. To those who have built it or heard one: is the drive channel meant to be so... different? The distortion sounds super compressed, bright, and fizzy. It's way hotter than expected, but it's very much unlike a cranked Fender or a lower-gain Marshall. A category of its own. A little splatty, a little velcro-y. I realize this is stupid buzzword Bingo.
The clean channel is amazing and to die for. I'm just curious if something may be wrong with the drive.
Thanks!
The ODS drive channel is difficult to dial in. I'm not surprised you're having trouble with it. The culprit, and the solution, is the trimmer pot that feeds the V2 circuit. If it isn't set just right -- and its sweet spot is VERY narrow -- you'll get too much drive, or so little that the drive channel adds nothing. You may also want to try the "Ayan mod": https://ampgarage.com/forum/viewtopic.php?t=33519 I installed it with 4.7 nF in parallel with 470K and I like how it cleans up the OD sound.

It is completely valid to be cautious about product background when the local shelves look so bare. Many people facing this issue prefer to buy CBD Oil locally through verified online networks that ship directly to our area with full batch clarity. It saved me a lot of guesswork and delivered exactly what I expected. Take a look at their laboratory documents to see if it fits what you are looking for.

Hi,
Is some one familiar with the hum for the Vibrato / Trem on F.ender Reverb PCB 4.0.
I have a hum when i switch the Trem on. Reverb is clean and quiet, amp is hum free and quiet.
It s a loud hum when i switch, with a 2 button switch the Vib on.
If this sounds familiar to you, please let me know. Suggestions, Tips let me know. Thnx in advance. Henri
An update. The 60 cycle hum is gone. I changed some grounding s. Also the PT was responsible for hum. One bold from the 4 off the PT was a bit loose. Then the ground shutting motorboating hum in the Trem - circuit. Alle measures and routings were good. After resoldering some main point s in the Trem-circuit , tadaa. Solved. I think or the .001 cap had a cold solder , or 1 leg from the LDR , which goes to ground had a cold - solder . So such a nice beautiful amp for some good blues rock southern rock

Hi, my 1st post here. I'm in Canada and just ordered the FOX30 PCB, and I'm wondering where i can purchase a bare chassis for this build. I order a lot of stuff locally out of Toronto, and also the U.S., but I can't find a chassis this side of the Atlantic. Anyone have a lead on where I can purchase one from plz??
welcome. Be careful when ordering a chassis from the US, our government is nailing us hard these days. Anything steel it seems.
Not on this side of the Atlantic, but have you heard of Modulus Amps? I've had good service from them on chassis and face plates. Shipping is not expensive and things come quickly.

Has anyone had any luck ordering parts for this board using Beta version spread sheet.
I'm having trouble sourcing JP1-JP4 on this spreadsheet. Also, they are not shown on the schematic or on the Layout. I have an mail in asking for clarification from Dr. Andrea and for any help he can give us.
The AA Dumble board has a Delon-type voltage doubler that feeds the 7812 voltage regulator from the 6.3 VAC secondary winding. Allows you to make 12 VDC from the filament supply so you don't have to install a separate 12 VAC transformer.
