DIY 50EH5 / 25EH5 Tube Amplifier

This tube amplifier project uses the parts from a junked Fleetwood console stereo. It uses a 6AX4 full wave bridge rectifier two 5A 400V fast recovery diodes. The preamp tube is a 12AX7 and the power tubes are 50EH5. I followed the basic ideas from Gio's DIY 50EH5 Tube Amplifier Project. This is my super sized version of the amp with all DC regulated filament supplies and even does a lower frequency response than usual because of larger output transformers (underneath the chassis).
