Having just followed this layout, there is an error on the first two radial electrolytic caps, the polarity is the wrong way round. Exploding electrolytics aren't what you want at the end of a build

Building to the attached layout works fine and seems to be similar to what was originally posted here. So, I'm not so sure there is a layout error.

Never really understood why using a xformer with too little secondary voltage, anayway. Alternatively use two small cheap print xformers with the two secondary sides connected.
I use a 230v (in EU that is) primary with 12 volt secondary => into a 6 volt secondary of the 2nd xformer and get (almost) the double voltage on the primary, like 300volt. Besides feeding the 2nd transformer, the 12 volt ac secondary of the first transformer is used as heater voltage for the 12ax7.

Chris, in you version of the Dlator, it appears that you are grounding the jacks at the sleeve through their connection to the chassis. Some builds have discussed isolating the jacks. Have you had any issues your way…loop hum?

It's quite a while later but in case anyone wanders across this in the future, I did use isolated jacks.
Hi, sorry if this is a dead horse, I am wondering if anyone has built the series/parallel unit as shown by Structo? I there any confirmation that the layout works?
Just curious if there's a BOM for this Dumbleator?
I looked around and don't seem to find one.
TIA
