How to search

sten gun
pages with both words
"sten gun"
the words together, as a phrase
sten OR sterling
either one (| works too)
sten -replica
leave out pages that mention “replica”

Without quotes, the last word also matches longer words that start with it (sten finds Stenophylla), and close word forms count (rifle finds rifles). Tick Exact words to match whole words only.

Other words for the same thing are searched too (uniselector also finds stepping switch), ranked below pages with your own words; the results say what else was searched. Quotes or Exact words turn that off.

Whole deep dives are listed first, then the pages inside them. Click a topic under the box to narrow the results.

Tick Photos to search the captions of every photo and diagram; each picture opens where it sits in its volume. The Show row narrows to one kind of result: volumes, deep dives, photos, parts lists, Library documents or downloads.

    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.
