Description: Precision 10-20 Tube and Set tester I partly restored this unit for my use. I did not restore the VOM part of the unit I have accumulated some documentation while I used the tester and I will include them.A detailed operating instruction which includes a schematic for the Model 10-20/10-22 tester.Also included is a tube setup data sheet that includes tubes not on the roll chart. A Tube Test Data for Roll Chart F2P the roll chart in the unit. A supplementary tube data chart for special and foreign type. An article by Bob Putnak that discusses the repair and calibration of the Precision 10-12 Tube tester. The 10-12 and the 10-20 are pretty much the same except the 10-20 has the VOM circuit included. Go to Bob's web site for more detail for the repair and calibration. I have included some pictures which show some marks on the wooden case. The unit is dusty as it has been setting on the shelf unused for a few years so I need to let it go. The Precision 10-20 is pretty simple I think to use and it goes pretty fast when checking multi tubes. The unit will need some cleaning, dusty, etc. Some of the buttons stick when pushing down but pop up okay when released. I enjoyed getting this tester to the point that it would work for me. I hope you can make this unit work for you, if not then do not buy it. Some of the carriers are a little rough so plan on opening it up to make sure things are in place. Due to some buyers actions I can not accept returns on this item. If you bid on this item then you must agree to this condition, thanks for understanding.
