Notes:
1. Email Weslee Kinsler with questions, comments, etc.
2. The 6V6 GT tube may be substituted for the 6K6 to lower power requirements.
3. C8 is for radio interference suppression and may be omitted.
4. The 5Y3 GT tube should be mounted in a vertical position and be well ventilated. The 6K6 and 6SF5 tubes can be mounted in any position.
5. Controls should have an audio taper.
6. The power supply portion of this unit may be used for anything requiring 290-320v DC up to about 3 amps.
