I have an original copy of Sams 62-16 along with the Riders info as a backup. I removed the CRT and put it away in a safe place. Then I removed the speaker assembly and covered the cone with cardboard. It was also put in a safe place.
As my usual customary procedure, I labeled all the resistors, capacitors, inductors, pots, etc according the Sams.
I then pulled each tube to be sure it was in the correct spot, cleaned it, tested it, and wrapped it in a paper towel and put away till needed. All the tubes tested good. Most were either Raytheon or RCA. The 35B5 audio output tube was a Ken-Rad. The 4 12SN7GT tube were all Raytheon with a date code of 9-18. Could be 9-13 though. The 25L6GT H.V. osc. tube had a date code of 8-48, and the 1B3GT H.V. rect. tube had a date of 8-52.
