Description: This 1931 Readrite Model 407 Tube Tester, Serial Number 9518, has been refurbished, tested and appears to be working properly. It is equipped to test early radio and audio tubes in the 01 to 99 range. It was advertised as a shop bench top tester but is obviously small and light enough to be considered portable. All sockets were cleaned and switches were burnished. The only passive components inside are 3 precision wirewound flat pack resistors which do not age and were left in place. The meter indicator lamp is good, as is the internal fuse. The original heavy card stock tube list in the lid and the operating instructions on the panel are present, in good shape and very readable. The original cloth covered power cord is in excellent condition. The case got a good scrubbing to remove all dirt and grime. The leather handle is in decent condition, as are the leather corner bumpers. The vinyl covering is in fair to good condition, with a few thin spots and small tears. The hard rubber feet are cracked and worn, but present. The latch and hinges have light oxidation, as you would expect with a 90 plus year old piece of equipment, but no heavy rust. The case measures approximately 11" x 7" x 4". Please see the photos for additional details. A variety of old, previously tested radio tubes, including 01A, 24A and 27 types were checked and found to have the expected readings. All of the socket connections appeared to be stable with no intermittency. Several of the most used switch positions displayed a bit of intermittent behavior but all worked after minor tweaking of the knobs. This tester will NOT test octals, loctals or miniature tubes! Please know what you are buying and always operate the equipment in a safe manner! Thanks for looking and, if you buy, for helping me keep my hands and mind busy while pursuing a wonderful hobby!
