Accurate Instrument Tube Tester Model 157 Manual and Tube Substitution Guide

[Thundersleet]

I recently bought a Accurate Instrument Tube Tester Model 157 ($22 auction). It has operating instructions. I scanned them and made a pdf. If you have one of these tube testers you really can't get accurate test information without the manual. So I'd like to share it if anyone needs it.

Here is the link for the Model 157 manual and the June 68 Supplement Chart.

Here is the link if you already have the manual but only need the June 68 Supplement Chart.

This link is for a Tube Substitution Guide I got along with the tester.

And while I'm at it here's a manual for Schumacher E-Z MIG and 105 Turbo MIG FLUX WIRE FEED WELDERS MODELS 90775 90778 90779.

I also have one of these valve (tube) testers, and am very grateful for your first link which works well and has given me a starting point. Also, it has enabled me to test and fix a radio in a few minutes (to a point). The second link works as well, and thanks for that, however the third one does not which is a shame because I could do with it.

Many thanks for sharing what you have though.

Kind regards

Sorry about the bad link, here's a fixed link for the guide only: Vacuum Tube Substitution Guide.pdf

Hi Thundersleet,

Just stumbled on this page today and wonder if there's any chance of a re-up on the 68 Supplement chart and Substitution guide? I have a manual but there's no listing for a 6EU7 tube! Thanks in advance, Dr Hepcat
