Hey guys, LOOOONG time boogie board surfer, first time rider. I know this forum is all but dead as theres not much love for the Stiletto anymore. But I just need to chime in.

I bought a used Stiletto Deuce a year or 2 ago. Ive tried mesa tubes, GT, and many preamp tube combinations. EQ's in the loop, BBE sonic stomps. All of these attempts have been to try and tame the "fizziness" that we all know and love(hate).

I recently took the plunge on a matched quartet of JJ 6ca7 tubes from thetubestore.com (great site btw). I specified its for a stiletto and they sent 4 tubes with a "31" rating on them. let me just say...wow. at band practice it was night and day, they round out the sound so much better than el34's. giving you the "body" that i was after and totally eliminating the "fizz".

We had a show last night, and the Stiletto sounded the best its ever been, aggressive, raw, and clear.

I play in a thrash metal band. emgs, tite gain, gain at 12:30 (believe it or not, but the trick is to crank the output section and roll back the channel volume)

oh yeah and a tungsol in V1 is key.

just needed to pipe up about this amp. Ive been wanted to love this amp, but could never get there.

PEACE

I totally agree. Even though it's currently not my main amp, the 6CA7's definitely sound sweet in my Stiletto.

Sounds interesting. I've had a stage I deuce for a few months now...still experimenting with the voicing. Do you need to re-bias for the 6CA7s?

No re-bias necessary, they are in the EL34 family along with kt77's.

I also went with the JJ6CA7 in my Trident. It really helped beef up the lows and tame the high end shrillness. It is no longer collecting dust!

Do you know if there is a difference in sound between those and the KT77's? I am due for tubes and may try something different. I've used stock Mesa EL34, JJEL34L and JJKT77 power tubes in mine. A majority of the time I've kept the KT77 in there because I like the added low end, but I do occasionally go back to the Mesa EL34 because I like the tightness and bite. The EL34L are warm and sound good, but for whatever reason I don't like them as much.

I remember reading an article that Randall Smith wrote basically saying that the power tubes don't affect your tone, but I definitely hear a difference between these sets of tubes, especially the EL34 and KT77. I don't think that the stock Mesa tubes sound bad at all in that amp, it just depends on what I like at the time.

Over the past couple of years, I've also been in the habit of using the tube rectifier on my dirt channel and using the spongy power setting. That seems to choke everything back a little and I like the way that it feels to play

Hmmm, it's been a while since I've had KT77's in the Stiletto, but they didn't set my world on fire and I prefer the 6CA7's. Now, in all fairness, I have my Stiletto's tone setting dramatically different these days. Personally, for a more classic sounding hard rock sound, I run the tube rectifiers on spongy mode myself. Gain is about noon'ish, treble and presence at 9:00, mids 12-1:00, bass the same as mids. At least, that's my rough recollection of my settings. I did a side by side with my Marshall AFD100 (my main amp these days) to achieve a similar tone.

I did a quick search and it looks like Smith meant there isn't a difference between tubes of the same type. Sp basically most EL34s will sound a lot lot other EL34s, despite manufacture and bias. Is that right?

I'm thinking about throwing some 6CA7s into my Stiletto Ace.

I used to turn the treble, presence almost all the way down and the bass all the way up. With the 6CA7s installed, I have a lot better eq control than when the stock tubes were in. It is not a completely different sounding amplifier but certainly the new tubes made a significant change.

absolutely, my presence is still basically zeroed out, but i can roll my bass back to basically 1 O'lock, and my treble around 11. raising the treble inherently raises the gain, so you can back off the gain to get a better tone. crank the master to get the power tubes cooking and this amp sounds better than ever.

I absolutely agree with you. This amp sounds a whole lot better when the power tubes are being pushed.

V1 : Tung-Sol RI
V2 : JJ ECC83
V3 : Shuguang
V4 : Shuguang
V5 : JJ ECC803 Gold Pin

Power : JJ 6CA7

Rectifier : JJ GZ34

This all sounds like a grand experiment!! Any issues with fitting these into an Ace combo? It's kinda crowded in there... :mrgreen:

I am sure you should be able to fit those into your Ace. I have a Stiletto Trident Head and it is crowded! Man this thing uses a lot of glass.
