Tube suggestions

[skynyrd77]

I got a jolida 502crc I was thinking about trying out some different tubes. For starters this is my first tube amp. It came stock with 4 tung sol 6550's what are some good choices for replacements . Thanks

Based on my experience with an older 302b, I would roll the pre & driver tubes before the output tubes, unless they are failing. If the stock small signal tubes are Electro-harmonix, there are lots of better sounding tubes to try.

Try RCA 12AT7 either grey or black plate. Those tubes play as good as Telefunken ECC 801s. The Tung Sol 12AX7 are usually a clean & clear sounding tube. Telefunken 12AX7 are a little warmer.

Tubes sound a little different in different circuits, so my advice is not exactly specific to your amp.

I like the sound now. But being its my first tube amp I got to play around. So ill look those up and give them shot.

As always, everything is system dependent, but in my 502 I love '60s JAN Sylvania 12AT7s as drivers, Tele smooth plates as inputs, and Tung Sol reissue KT120s for the power tubes.

The EH 12AT7's would be the first to go, tried them, they are not very good in my amp. Mullard CV4024 (12AT7WA) and GE 6201 (5-star) are waaaaaay better and still reasonably priced.
