Volumes

1. Vol 1 Overview: A Regulated HV Bench Supply for Tube Work A 1962 kit that turns any junction of the bench — a chassis punch, a socket, and an idea — into a working tube circuit before lunch.
2. Vol 2 How It Regulates: The Series-Pass Tube Regulator Six tubes, six silicon diodes, and two selenium rectifiers turn a raw 600 V bus into a bench-safe, glass-clean 0–400 V rail — with not one transistor in the loop.
3. Vol 3 Inside This Unit: Hardware, Devices, Outputs & Metering Two 6L6 pass tubes, a 6BH6 error amp, and a pair of glowing 0A2 regulator tubes, all bolted into a 13-inch chassis a physics undergrad could kit-build in an evening.
4. Vol 4 Using It: Operating Procedure & HV Safety A step-by-step bench procedure for a supply that can put 600 V across your hands before you've even touched the output posts.
5. Vol 5 Calibration & Refurbishing A 60-year-old kit-built supply that once flexed to 600 V raw B+ does not forgive a discharge step skipped for convenience.
6. Vol 6 Cheatsheet & the Generational Pair Everything on one laminate: specs, warm-up steps, refurb order, HV DON'Ts, and the honest IP-32-vs-SP-2717A comparison.
