Green God SE 6Bq5 tube amplifier 2/2022
Green God "Son of God" SE Tube Amplifier
A second "Green God" SE tube amplifier project is in progress.
PT was taken from a Motorola phono console mono push-pull tube amplifier that featured (2) 6V6, a few 12AX7's and 5Y3 rectifier. AES PT-31 5K/8 OPT are on order.

Green God SE 6BQ5 Signal Circuit Wiring
Magnavox DG SE-1
Deathtube 667 chose the Magnavox DG SE-1 circuit, a popular project on various online audio forums. There were some adaptations to the DG SE-1 circuit to allow for higher B+.
The amplifier was wired with Kimber TCSS 19 ga. clear jacket stranded copper but not "optimized" per MLP design team requirements for maximum "transfer efficiency" as this is a standard SE console amp project

Green God SE 6Bq5 THD% vs. Power output
Harmonic Distortion Measurements
THD% vs. Power Output at 1w, 2W & 3W levels taken with ARTA.
Right Channel: Sovtek 6BQ5 Left Channel: JJ 6BQ5
THD @ 1W = .54% THD @ 1W = .58%
THD @ 2W = .87% THD @ 2W = .88%
THD @ 3W = 1.35% THD @ 3W = 1.26%
Note: driver tube is Telefunken ECC83/12AX7.
