The cathode resistor in my Tweager is burning, an there is no sound comming out of the amp. I can't see wich resistant it had since the script is burnt away. Have you got any idea, what can cause that? The tubes are JJ 6V6S.

@ prolly a bigger issue at hand causing the resistor to blow. Bring it into a shop.

@@tmsb8059 I have torn out a bunch of components and ordered new ones. Let's see what that does to the problem.

Nevermind. I got the help I needed and figured it out. If you're not doing a crossover, which is not my case, all you have to do is put all the positive wires on one side, all the negative wires on one side, and that's pretty much. Say for example you have a 3s 18650 battery pack with BMS for a DIY induction heater. On the BMS, you have a -ve output and +ve output. So say for example you need to power a blue LED and you only want the blue LED to turn on when the slide switch goes to the other side, or battery powered mode. Two negative wires and one positive wire on the BMS from those -ve and +ve outputs. One negative goes to the NC, or NO terminal on the slide switch. The other goes to the negative of the blue LED. The positive wire also goes to the NC, or NO terminal, on that same side. On the COM terminals, you have a negative and a positive wire. Those go to a MOSFET module, and the MOSFET module powers all the other components of the induction heater. But on the COM terminal where the positive is, you have another positive wire which goes to a 20K ohm resistor for the blue LED. On the other side of the slide switch on NC or NO, you can attach the positive and negative wires from a DC power jack like a 12v one or a 1a 30v one. So the way it works is you have the induction heater powered by DC input, battery powered, or off (On-Off-On). And that's pretty much it. Basically, just have all the positives and negatives on one side. You can have multiple wires on the BMS from the -ve or +ve outputs or from the COM terminals of the slide switch to power other things such as a blue LED or supply power to the MOSFET module to power the other components.

Silly. Bass players have had access to much better technology for years, than what you're talking about. You're living in the dark ages. School yourself about what's going on in the world before you act like a know it all person.

The reason I don't is because once you've got your trace cuts mapped out you can make your board cuts relative to those instead of counting the entire length and width of the board. Seems like a small thing but this whole process can be long and tedious so anything to make it more efficient helps.

The smart people would use a relay instead and get electricity to do the switching job instead.

found it. thank you!
