Build your own ALL-IN-ONE II Test and Calibrate Unit for Hickok 539B and 539C Tube Testers

VHSystems is now offering the new All-In-One II that replaces the previous model sold by TubesLab on ebay.

William (Bill) Eccher Jr. is retiring for manufacturing and is offering for PERSONAL use only license to the ALL-IN-ONE II.  He provided the instructions along with a part list and pictures of the build process.  I’m his son and manufactured the panels with help from my neighbor, all holes were drilled on a CNC system and we had it anodized and laser etched for the lettering.  This would be expensive to do an individual bases and if there is demand we might do a run of twenty or so and would provide a pricing estimate if the demand is there.

In the Manual is the direct email to William (Bill) Eccher for basic questions if needed.

List price: Free for Personal Use ONLY
