Hello everyone! Andrea here :) I wanted to share with you some information about the power supply section of my Dumble PCBs. As you might now, I have designed a single PCB that supports several different models (102, 124, 183, 3rd gen, etc.). This means the filtering section is modular and the same board can be configured for different versions of the ODS and also for different cap styles (radial and axial). For this reason, there are some jumpers here and there to be installed: I've noticed a couple of fellow builders have had some issues in getting this part of the amp wired correctly. Hence, in an attempt to make your builds even easier, I'm sharing the copper traces that connect the PS components. Be particularly careful with the positive side of the C25/C26/C27 caps, since there are a couple of pads close to each other that might be mistakenly wired. Hope this helps, Andrea AA Electronics

Hello boys and girls! After your numerous requests, I'm adding 3 new products to the PCB portfolio! These are: --> THE TRAIN: Trainwreck style PCB, with which you can build the Express and the Liverpool models --> THE MATCH: Matchless style PCB, with which you can build the C30, Lightning and Spitfire models --> THE 18W: Marshall 18W style PCB, with which you can build the standard and the TMB models Given I'll start with an initial small batch, I wanted to know how many people would be interested, so reply to this thread if you are planning to get any of those listed above :) that will help with the manufacturing :) Also, what colours should we go for this time? I'm attaching the layouts :) Cheers from London! Andrea AA Electronics
