![Build A Power Supply - With Junk Box Parts! [The BC-348 Series.]](http://i.ytimg.com/vi/nX87kwSshZ8/mqdefault.jpg)
Hi RJ, I accidentally stumbled upon your video. I ordered the exact same kit back in December of 2020 but never got round to building it. Back then I had already noticed they included an 18650 battery holder in the box to power the filaments, that would have destroyed the tubes instantly. So these kits are very low quality and may have the wrong components but luckily I have a large junk box, a MM and an LC meter. If I remember correctly there were 3 versions of the kit; just the PCB, the PCB with components and the complete kit with wooden bottom and plexiglass front. So the people without the front would have to solder everything straight on the PCB. That is probably why it confused you. Looking forward to part 3, maybe you can give a summery of all the things wrong or confusing with this kit in the description. Maybe even make some improvements. With winter coming it is a nice time to build it myself and use your videos as a guide. Thanks for the videos, liked and subscribed. 73 de PA land.
Welcome aboard,
Part 3 will be out Tuesday (tomorrow) I am working on it now. This is exactly what it will be. I will get it working and show all the issues I found and how to not make them yourself. I think I am going to post a diagram showing the correct wiring of the coil to save people the trial and error I’ve had. Your explanation of the three kits does explain the board being designed for the parts to fit on the board. Don’t know why that didn’t dawn on me.
Thanks for pointing that out. I’m glad you found my video maybe I can save you some hassles.

Thanks for showing how you constructed the coil. That has been immensely instructive. Also, thanks for the tip with the Q-Dope. I'll check out your video on how to make up a batch. I assume it's probably acetone solvent with styrofoam packing material dissolved into it. I have a few other projects standing by that require similar coil construction so this will jump start those for me as well. Watching you work through the stages and trouble shoot along the way has also been amazingly helpful. You've done a brilliant job explaining the whole process so that even I can understand it. Now on to part 3.......(KO6ABI)
So glad to have someone I was able to help! Turns out the trick to go Q-Dope is very white packing material and MEK, acetone failed when I tried it.

@@LynxElectronicsLab I wound up ordering some Q-dope on ebay. Looked like the bottles were still good and the price wasn't too bad. But the solvent does tend to find it's way out of the bottle over time. So it's good to know that MEK solvent is the way to go. I can get some MEK solvent to have on hand in case I need to resurrect any of the bottles of Q-Dope that might be running low.
The stuff I ordered online was bad!!! It was black water. When the solvent goes out it gets thick and you can add solvent. This was different. Never seen it do what this did.

Hey RJ, just a couple of my "wonderful" thoughts. Maybe check the tubes on your tube tester. Did you mount the pcb stand offs upside down? Screws are still too long but maybe they were needed to run through the piece of wood. I was wondering how much MORE complaining there would of been if the DLA products had the same level of kits and assembly directions and support as the radio kits you been working on. Plus every one would have to write their own PIC code.
Rick, you might be correct I might of was suppose to put the long screws in from the bottom and the plastic threads through the pcb and nut them. Still would not need that long. As always I do make mistakes. It would be nice if I didn’t have to fly blind on the kit. Yeah I do not think we would have had thousands of working units out there from all the diy builders if the quality of instructions were this lacking. You deserve much credit for the wonderful wiki you created for us. It really helped having all the info organized. 👏🏻
