Custom Ampeg Heritage B-15 schematic

This project is a custom modification of the original Ampeg Heritage B15. You can download the schematic HB15.pdf.

- Use 6L6GC valves that support 500V at the screen - Always checks that all capacitors are discharged - Even if the 470k 2W resistor shoud discharged the capacitor

Valves used in this project: - TAD - 6L6GCM-STR REDBASE - Philips USA as JAN 12AT7WC (6201) [NOS military grade] - JAN 6SL7WGT Philips [NOS military grade] - Shuguang 6N9P J level [NOS military grade]
