I didn't see this on the site and I know Bob stops in here sometimes, but here goes. My Reinhardt JKC33 has the external bias points and I want to check the bias on the amp. I have a cheap $30 RadioShack multimeter that I used to use for my Allen Old Flame. The Allen just had a simple knob and was very easy to bias, but the JKC33 has a dial with numbers on it and there is also a little number in a window that increases or decreases as you do full rotations (2, 3, 4, etc.). What do those numbers all mean? Anyway, when I set my multimeter to "2mA" I get a reading of .020. Am I supposed to be doing DC millivolts? At any rate, I have not changed the bias and have left it where it is so as not to damage the amp or tubes. I'm really not even sure where 6CA7s are supposed to bias. Here's some additional info. on the multimeter I've been using: "15-Range Digital Multimeter. Measures AC and DC voltage up to 500V, DC current up to 200mA and resistance up to 2MΩ"
