Review Of Penta Labs 3-500zg Tubes In My Personal Kenwood Tl-922

Here I show Penta Labs 3-500zg tubes in my personal kenwood tl-922 Linear amplifier. I also show my preferred tune up method
Note, while zoomed in on the amplifier meters, I switched multi meter to the rf output setting. After showing grid current
Enjoy

Like that you have a D-104 mike Love mine bought it when they were new boy I am so old. So far I have had good luck with the Penta Labs tubes that they make in China. A lot of Hams don't like them but I am glad they provide us with these tubes. de WB7ORB

Awesome video. Great job explaining what you're doing and why and what happens if you push it too hard.

Is it worth grounding the grids ? I have a L4B I've been thinking of doing . Thoughts?

Please refer to one of my videos on a drake l4b

How does a TL-922 compare to an Ameritron 811-h? 73

[@amprepairguy]

Both Great Amplifiers but different power classes

Where do you buy your Penta 3-500 Z tubes?

[@amprepairguy]

I am a penta labs distributor, my customers pay penta direct and has penta drop ship the tubes to me. The customer pays the dealer price , no markup.

[@hunt555fish]

@@amprepairguy thanks for quick reply.

[@robertbobbitt8448]

Why Oh Why did you touch those tubes bare handed

[@amprepairguy]

Tube isn’t a halogen light bulb. Halogen light bulbs should not be touched with a bare hand. Will shorten its overall life span due to the oils from your skin
