The JJ 5U4GB works great in my 20 watt audio amp, replacing a physically smaller Russian full wave rectifier tube. Check the measurements to ensure a fit in your application.

Got these to replace tubes damaged in transit inside an amp. Identical replacements that work as expected. Shipment and delivery were timely and quick, and well packed.

Very nice sounding tube, sorta' luscious, sweet, and full range. My NOS favorite 5U4GB used to be a Tung Sol, but this out-performs NOS tubes in my two stage direct coupled amps. I LOVE what a DIRECTLY heated rectifier tube does. I have been told the Electro Harmonix 5U4GB ( handled by Antique Electronic, and reasonably priced !! ) has a little more " snap " to it, dynamically, but I was also told it takes 200 Hours of playing to break-in to full bloom. This JJ takes maybe only 15 hours to break in - in my DC SET amp circuits. Amazing, two modern tubes that each beat the old timers.
