Thomann in Germany describes them so, and I've seen similar descriptions. Of course that doesn't mean that it's true, though. Here's a link to Mesa tubes at Thomann I was able to get a new set at a lower cost because my newly bought set of Mesa STR-440 Yellow was defect. They work but rattles...

Okay... The funny thing is that they are being advertised as "soft", the yellows as "soft-mid" and the green as "middle" and the "grey's" as aggressive. Some not uncommon believes are the the red's have an earlier breakup due to lower idle bias current, and that they have a softer sound. And I...

Well... They are on the way, probably have them by Monday so I'll soon find out myself. :wink:

... what can I expect tone-wise??

Rats! :evil: Got a new delivery notice from the reseller of the SPAX7 tubes today. I have to wait a few weeks more... The funny thing is that they had a good deal on them, but had none in stock. If it weren't for the deal I would have refused to buy them and get a refund. But as I said; it was...

My other amp, apart from the 5:50, is a Line 6 Flextone III+ with an external cab and a FBV Shortboard. It's basically a POD X3 in a combo stereo amp. It does not get as much playing time now since the Express arrived, but it really is a god amp. I have had it for several years and before that...

Nah... Not yet :( The delivery is due to the reseller at the 29'th. If lucky I will have them next week. :D A funny thing happened to me last night at a gig. Had the 5:50 out for the first time. First off I've got lots of WOW's from fellow musicians when they saw the amp. Then at the first...

When cleaning out old stuff at work today I stumbled across a box with unused tubes. Sylvania's and RCA's. Even six or seven Nixie tubes. :D Anyhow, the only really useful tube I found was a never used Sylvania 12AX7A/ECC83/7025 tube in it's original box. :) Might actually give it a try in...

Yes.... In size D... :P

He's probably having trouble uploading Super-8 movies on the Toobe. :lol: :wink:

Now, that's a very interesting question. And now for the REALLY interesting one: What Boost in Front of 5:50 to get GOLD? :mrgreen: Find the answer and all the alchemists will be ever grateful!

Agreed, Tubenator. My thoughts also. Unfortunately I have to wait for my tubes. A Swedish reseller had a deal on the Mesa SPAX7 tubes, but none in stock. Since it was a good deal I ordered there, not knowing about the stock situation. I wont expect delivery for at least two weeks. :( On the...

Thanks vfb. I've read all about it in threads at this forum. :D I appreciate the effort being made of buying and testing lots of tubes finding the right combination of tubes. But knowing how my mind works, it's not the right solution for me. As stated in my earlier posts this solution does...

I've just ordered four Mesa SPAX7 tubes, three for my amp and one spare. (Already have 2 installed) I'll report back when I've tried. May take a week or so for delivery. /G

Thanks Tubenator! That might be the way to go for me too. I just want to keep it simple not having to have 3 or 4 different tubes in stock. I would never remember which to put where anyway. :? The hiss I hear is a white (pink really) noise that is the same whether or not the guitar is...

On second thought... Just disassembled the amp. It's very neat. It's so neat I'm having second thought messing with it. Not that I think I couldn't do it, but it's so nicely built, and if I would do a mod I must nail down the source first really knowing it will help. Tube swapping is simpler...

Noise = thermodynamic noise = white noise. Some may call it hiss... :D Yes, I know, but I am of the opinion that this should not be necessary, if you choose not to use the most crappy tubes that is or very high gain tubes at the first stage. (V2 I think) I was looking for an answer if anybody...

Got my Express 5:50 a couple of months ago and while loving the tone I start to get annoyed about the noise level. Purchased mine used in mint condition and my first measure was to put new tubes in V1 and V2 and new power tubes. For the V1&V2 I bought some MESA SPAX7 as they are supposed to be...

Just a thought. Have anyone tried? I'm having trouble dialing in a decent low volume setting. The master volumes is going from zero to quite loud in about one or two millimeters from where the potentiometer taper leaves the left position end stop. Clearly the master volumes is linear...

"I can't hear any volume difference at all when I plug the 16 ohm cab into the 8 ohm jack as compared to the 8 ohm into 8ohm." Yes you're right. I do not think you (or I) would either. The volume drop depends on the transformers secondary impedance and how it performs, and the theory becomes...
