Hey guys! It took the good part of this week's evenings, but I finally completed the PCB :D It supports both LDRs and Relay switching, plus elevated heaters and V1/V2 DC supply. All in a 400x78mm footprint. Attaching layouts and schematics, would love to get your opinion guys! Still haven't fully de...

Hello boys and girls! As you know, I have done several PCBs in the past, in particular hot rod, marshall and fender style boards. I got a lot of requests for a SLO style board, so I took some time last week to prototype a board in Eagle. I’d love to pick your brains on some improvements I want to ad...

Hello boys and girls! Queen's funeral here in the UK today, and it's a national holiday. This gave me some time to pursue some projects I always wanted to start but never had the time. As some of you might now, I have been selling PCB boards through my website for a while (https://www.aaelectronicsp...

There was a typo in my original diagram. I went back to it and modified it accordingly. This is how I'm thinking about it - keep in mind I'm assuming a PT with center-tapped HT.
Would this be in line with modern safety standards?

Hello everyone, I have a question on HT fuses. Dumble didn't to put one in his design, but I'd like to add one to my clone for extra protection. Will the attach diagram be a good way in your opinion to upgrade to Mains + HT fusing?

That was fun Huh! That's one of the F words I was saying. I kept hoping for an epiphany to point out some glaring obvious flaw, and when I finally got it I just shook my head and laugh/cried for a second. Thanks for the method. I'll employ that when I build my 183 :) Amazing work Prof! Just saw thi...

Hahah really? To be fair I thought the purple color was a bit funky, but the overall result mesmerised me (attaching some pics here)! But again, quoting Cesar, "de gustibus non disputandum est" :D thanks for the feedback! https://i.ibb.co/4VxNV49/IMG-7355.jpg https://i.ibb.co/MsYLHbh/IMG-7356.jpg ht...

Hello everyone! I'm planning to have a new version of the boards produced soon, and I'd love your feedback. What are some things you would like changed in the boards? Are there some errors you found that I can correct in the next revision? Any comments regarding the documentation? I saw some of your...

Happy New Year everyone 🙂 since London is in complete lockdown, I dedicated my last two weekends to create a board for Fender amps, that'll work for most of the tasty blackface models: Deluxe Deluxe Reverb Vibrolux Tremolux Band-Master Concert Vibroverb Super Reverb Showman Bassman Dual Showman Twin...

Great to see my board at work how's the status of the amp?

Nothing really special about the small box, build a JCM 800 with a large 1st stage plate load resistor, 2k7 cathode resistors on both 1st and 2nd stage bypassed with 0.68 u caps, 820r 3rd stage // 22 u. Add snubber caps and grid stoppers to taste... Fairly standard Friedman, conventional master aft...

and what do you guys think about Steve's "one wire mod"? http://home.comcast.net/~mamp17/Misc%20 ... 0Info.html

Hi guys, I've built a Marshall 1986 Bass 50W last year... I love the clean tone I can get out of it, however, I'm not able to get any crunchiness at acceptable volumes - lots of headroom... I tried to implement the Lar Mar PPIMV mod, but to me it sounds too harsh and not "creamy" enough... yesterday...
