Hi Ron,
Yes, I have a variac.? My plan is to use a Tripp-lite isolation transformer I modified to be truly isolated.? Plug the variac into it and from the variac connect to the dim bulb tester with (3) switchable bulbs of different wattages.? Have all the parts just need to put the dim bulb tester together.??
Glad you brought up using the variac only.? My understanding from YouTube is that if any shorts are present then the bulbs should limit the current and prevent any damage.? Not sure if this is true in all cases but it sounds good.? I have been slowly setting up a lab and acquiring test equipment.? My ham radio gear is from the late 70's I bought new but has been sitting.? My heart would drop if I saw any magic smoke from the FT-101E especially with hard to get or unobtainable parts.? I would like to get test equipment for transceiver repair and alignments.? Not sure what you use.? I purchased a two-part re-cap kits from eBay pending installation.? Need to find out if any alignments will be needed afterwards.? It's been slow but lots of fun along the way.??
Thanks for your help.
Dan
