Quick question about tube amps

daniloreyes,

You are in Oregon.

If JJ makes the tube type(s) you need, then purchase your tubes at:
Eurotubes - Vacuum Tubes by JJ Electronic - ECC83, 12AX7, 6L6. 6L6GC, EL84, EL34, KT77, KT66, KT88 - Eurotubes Inc.

Or, design and build an amp using all JJ tubes.

They do re-testing, plus additional tests to the JJ tubes they get from JJ in Slovakia.
I have never had a tube failure from them, they are very well matched, no noise, all good strong tubes.

They are in the greater Portland metro area.
I call them up, and then drive over and pick them up.
Nice!

JJ tubes have improved a lot from decades ago.
The guys at Eurotubes have gone to JJ in Slovakia several times.
I also know the guy that designed several kinds of test platforms for Eurotubes.

You will not go wrong with JJ tubes from Eurotubes, unless you exceed the data sheet specifications.
In some cases, you might even exceed the tube specs and come out OK, they sell many of their tubes into Guitar amp applications too.
Talk about exceeding specifications!
