I voted EL84. Man, they are getting slaughtered by EL34's and 6L6's!

So far I'm really digging kt-66's




It is really a hard question to answer. I think it really depends on what amp you are using. I have a couple old Silver face Fenders. On is a Super Reverb the other is a Deluxe Reverb. 67 or 68 not sure, bith drip edge amps. Te 6V6 in the Deluxe are awesome. They are old RCa types also & they sound heavenly. The SR has 6L6 & they also sound superb.
In my Marshall(i have a 900 50W combo) I have EL 34's and its a good sounding amp.
My Bogner Shiva also has EL34's. again great amp & great tone!
My Komet on the other hand can take any kind of tube. Since I have had this amp I have had KT77's & EL34's. I think it sounds amazing with EL34's

I used to EL34s in my Dual Rec when I was more into bright, hard (hard like a sounds. I believe Strapping Young Lad did the same thing. They were great for the clean tones. Then just to try it out I switched to 6L6s and I prefer the slight compression it gives for thundering riffs and the darker character.
I like the sound of my JVM as it is (the only thing I've done so far is take out a component to reduce the gain somewhat and put a surplus military tube in V1). In fact one thing I've started to get used to about the JVM that the best sounds for aggression come from MORE gain. So it's the polar opposite of the Recto, which I set the gain just on the edge before any fizz happens and let the "bigness" of it's voicing and digging in to provide the sound.
I hear a lot of people changing to KT77s in their Marshall JVMs. But I'm debating about whether it's worth changing something I'm already happy with. If I'm really missing out on something that great just by keeping the traditional Marshall power tubes... Has anybody hear with a JVM change their power tubes? If so, what where your results?



I like em all.
Currently I'm running one 6L6 and one EL34 (in a P-P circuit); sounds a lot like KT66's but with a lot of extra overtones.
Actually. I have four other Glassman's hanging out in the man-cave, each with totally different setups...and totally different sounds.
Now operating part time: Glassman Tube Amps...repairs, rebuilds, restorations & modifications of tube equipment.
Still building: GlassMan Amplifiers (25 watt, all tube, single channel w/reverb, single 12" combo) and some more designs in the works.

That's interesting, a 6L6 and EL34 sounding kinda like a KT66. I can see that. KT66's remind me of the band Cream.
