So, I got a good deal on a kit for a BF Vibro Champ Kit, when I got me JCM800 kit and figured I would do the Champ first. I really want to understand things as I go, and am realizing that I have lots to learn, but constantly reading stuff online seems to leave huge gaps in my understanding.
There's lots of info, but sometimes I wish there were more pictures online with an arrow that says "this is the part I'm talking about" when referring to a bias pot or which pin to touch with a dmm to measure plate voltage or whatever. Also, I was just thinking that if someone ever made a website that had tonnes of pics or video and sound clips with instructions on certain stuff, they would be my hero. For instance; Sometimes I wonder if I am hearing crossover distortion in my amp, but who would ever tell me what that certain sound I dislike is. Maybe I just have bad preamp tubes or just generally prefer power tube distortion. Maybe I just need other friends around that are into amps.
Anyways, I'm grateful for you guys and all you do to help. Ok, I'll stop my rant now so I can ask my stupid question.
I see that on my Champ OT there are 2 wires on the primary lead side; one red (marked 'B') and one blue (marked 'P'). What do those letters represent and does it matter which one is used for what? Obviously, the secondaries are way easier to recognize the purposes for because they are marked according to impedance (0, 4, 8, 16).
So, about these primaries, one goes to pin 3 on the 6V6 tube, and the other goes to the end of the turret board by a big cap and then to pin 8 of the 5Y3 tube. Does it matter which one is the red (B) wire and which is the blue (P) wire? Feel free to explain why if you feel like it.
Thanks
