tell me all about the triaxis

[JimAnsell]

i scored a 2:90 for only 400, so i'm thinking about picking up a triaxis too.
can the triaxis do mark series tones well?
what is this phat mod all about? is it good or bad?
are there any settings secrets i should know about?

What up Detroit dog?! :twisted:

$400 clams is a great score. I've been working with this amp for a long time. Here's some things I've learned:

Get some EL34's and put them in the Class A slots. You don't need to mod the amp, just plug and play. I'd recomend some new ones, and tell your vender that it's for the Class A'sof a 2:90 so you can get a set that will sound their best. This will fill out the tone, and give the tone more cut and grind. Make sure you know which slots are the Class A ones. On the newer models it's different than the older ones. Mines older with a blue jewel light with a diameter approximately of an ink pen; and the Class Aslots are the outer left and right slots.

Also, with the EL34's in the Class A slots, you'll basically have 2 amps. So when kick in the half drive which only runs the class a slots, you'll have roughly a 50watt el34 amp.

Don't bother with the Deep mode. It has a ****** 60hz hum to it. You can get enough bass by using the Dynamic Voice on the TriAxis and without the hum.

The Modern is cool to. I boosts the upper mids to give a more difined sound.

My TriAxis has the phat mod, and I don't like it. I think it's way to loose and washy to use at all. If you want a recto tone, don't get a Tri with the phat mod.

Just FYI Half Drive does not change anything in the power amp section. Half drive just distorts the 12AX7's inside of the 290 more. You still have a 180 watt amp unless you pull out the tubes or add a "simul/class A" switch. I find it is easiest to just pull out the middle 4 tubes and plug my speaker cabs into the next lowest impedance jack (IE 8 ohm speakers go to the 4 Ohm jack)

I've got a Stereo Simul-Class 395 and was wondering if you knew if it was possible to use EL34s in the class A positions on this amp? It has the Simul-Class/ class A switch stock, but I'm not sure which sockets are the class A pairs... Thanks for any answers!

People do use EL 34's in the 395 but you have to leave the lid off in order to do so or try and find some short EL34's (6Ca7's maybe?). To find the class A slots turn the CLass A/ Simul switch to Class A and watch the tubes. Whatever tubes that have a blue haze to them inside the glass are the Class A tubes. You might need to turn out the lights to view this.
