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

you plug the tube in and it worked, what else can be said...

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

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.

Great tubes

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

Longer than the Sovtec it replaced. I didnt measure voltage or test it otherwise but it seems to run louder in my Tweed Deluxe and perhaps a bit brighter too.

Like most with vintage tube amps, I am a bit alarmed with the so-called 5Y3 rectifiers being sold these days and their higher output voltages. Well, you can relax with this one. I measured it compared with the Made in USA Fender labelled tube in my old SF Vibro Champ and here are the results: with 122VAC line voltage in, the Fender 5Y3 outputs a B+ of 384V and the JJ 5Y3 outputs 382V. That makes them pretty much identical. I have been practicing and gigging with this tube every week for about 6 weeks with no problems either. I just ordered another as a spare and hope JJ keeps making these! Thanks JJ!

Works great!

Decent tube
