It uses the standard LM317T variable regulator and has a range from 1.5V to 11.5V. Standard value for R2 (program resistor) is 240 ohms, but I didn’t have a small enough pot to give me the voltage range I wanted, so I bumped up the value of R2 to 1.5K. 240 ohm resistor in ...
Construction of a DIY Hi-Fi preamplifier using a 5687 vacuum tube in a single-stage circuit. The cathodes are biased using an LED CCS. The power supply use an RCA-83 mercury tube rectifier.
–here’s the schematic of the EQ http://i.imgur.com/ZWmwI01.jpg…you can integrate it the way it is in the original amplifier. Or you can put it between my version of the preamp and the power amp. –you can build the power amp section of Firefly amplifier using ECC82. I would...

I used to match power tubes in an amplifier by measuring the tube operating temperature. It takes a large lot of tubes, but same tube dissipation with same operating bias point and same tube gain is matched to me. leadbelly Member Joined 2002 2024-07-30 5:12 am #2 Not sure of your...
