Nope. I just talked with them. Its 200 for 2 boards and 2 x 6 matched JFETS.
Confusing though eh.. I thought the same.

Phase Inversion Switch

found that looking for means to invert phase... not sure if its quite right. would be interested in critical opinions of others. I suspect (without knowing) that impedance issues might arise?

i might forget it all together and, as advised previously, deal with it down the road if i can. Thought id share the info incase others find themselves pondering the same ideas

Hi folks,

I have what is probably a dumb question, most appropriate for budwiser, as it is his picture, but I am guessing many can answer it. The link is to a picture of budwiser's power supply, which I am trying to copy. This is my introduction to electronics projects.

My question: in Wayne's schematic, he runs the hot line from the wall into the fuse, than to the transformer. It looks like in this photo the neutral is running to the fuse. I assume I am missing something obvious, but would appreciate it if someone would tell me what. I am a trial and error kind of guy, but not when it involves 120 volts. Thanks!

I think if you look closely the hot wire goes from IEC connector to a switch and then from the switch to the fuse holder and on to the transformers.
It might be a good idea to build a bulb tester; saves a lot of blown fuses etc.

Yes, the hot comes out of the IEC plug, into a switch, thence to the fuse.

Always fuse the hot.

Since the BL version is more or less unobtanium these days, have anybody built the v.2 with GR types? Operating points could be adapted, but is there any loss of gain??

My power entry module has both hot and neutral fused for some reason.
