The 5AR4 is listed in the foreign & supplementary test data. These are available on eBay for $10 and well worth the price. (Glendale Manuals)
Fil: 5.0v selectors: 8200-6400 bias: 0 shunt: 68 mult: SH press: S3 min mut cond: 650 note 1: For dual triodes make normal leakage test first, then repeat leakage test for second section with button S8 pressed down and held. Proceed with 1st section Gm test with S8 released. For 2nd section test on all dual tubes, press down and hold button 8 together with button listed in PRESS column.
