I'm definetly NOT a appliance op!:) Heck, most of, if not all of my gear is old tubie equipment from 30 40 years ago. There's just something about a tube rig that a solid state rig can't compete with. Most of my gear is older than i am (age36)!!! If it has problems i can fix it. In fact, most of the gear has been worked on by me several times.
ALL of my gear is the latest solid state stuff. The FlexRadio inclusive. Oldest rig right now is the IC-706. If any of it needs repairing, I repair it.
You are bragging about being at the forefront of 50 year old technology?
Now that you've gotten a handle on the thermionic valve you would do well to start delving into solid state electronics.
