JJ Electronics Amplifier Tube (T-5Y3-S-JJ)

Decent tube

This was a spot on replacement 5Y3 for the Fender Vibro Champ. The previous hum heard in the amp is gone and output is increased after the vintage 5Y3, stamped West Germany....was replaced. That tube is kind of cool as a nostalgic piece I guess but useless in the amp. The JJ is not a weak 5Y3 like others out there...Anyone who tells you a 5Y3 is good until it dies probably plays with an inferior and failing rectifier. Easy circuit fix for little money. Cheers.

When I built my 5E3 Tweed Deluxe clone 6 years ago, I read that it was important to use a NOS 5Y3 rectifier to get the right voltage for the 5E3 circuit. Lately Ive been reading that these JJs are the one current-production 5Y3 that delivers correct voltage, and theyre getting very good reviews in general. So when my NOS Raytheon bit the dust I decided to try out one of these JJs. Well I guess that Raytheon had been tired for awhile. In any event, my Deluxe now sounds noticeably brighter, cleaner, and more articulate than before. Very happy with the results. Great tube at a great price. I just ordered another for a spare.

Arrived earlier than expected, and in working order.

My old 1930s Ward Montgomery Airline AM radio had a 5W4 in it even though the socket and schematics called for a 5Y3. Replaced the old tube with this one and couldnt be happier with it.

i like because i need this kind of product

Jj tubes are the best tubes for the money (period). I use a lot of amps and have all kinds of vintage and NOS tubes and they sound great but JJ tubes do the job and sound good too at a much more reasonable price.

Successfully brought my silverface Fender Bronco bucking back to full volume.

Did an excellent job of restoring my 1960s record player

Good as original 5Y3 tube
