Solid EL84. Apex matching for my cathode biased amps is great. Sound great.

These tubes are great. They really made a difference in my Vox AC15. Well worth the price which wasn’t bad at all either.

The el84 JJ tubes were packed very good. Great service and fast shipping. The JJ'S sound great in my Jolida 102b amp.

Thank you for the quad of El84 tubes I have had good experiences with JJ tubes in the past, and these do not disappoint. I was happy to find a set during the current tube 'panic' , and at a reasonable price.

Prompt and safe delivery, as always.

Great tubes. They do sound different than the Chinese tubes they replaced in my AC30C2. To clarify, they sound different but not better or worse. The sound is less bright in the middle. I don't know how that translates to other Amps and Speakers but you will need to relearn your Knob positions if you have a specific sound you try to repeat. I would buy them again.

I ordered spare tubes for two of my guitar amps. The folks at Amplified Parts helped me pick the right tubes and shipped the ones that were in stock the next day. The tubes that weren’t in stock became available a few days later and shipped a couple of days later. Given the scarcity of tubes, I’m happy with the support I got from Amplified Parts. They are my go to tune source.
