What are the tonal characteristics of 6550s?

 

[Duolos]

Incredible punch and headroom, 6L6 type cleans, tremendous clarity and note articulation.

 

[Peter Diezel]

Please let me write a longer post after the Frankfurt show

[flownomis]

please appology for my unpatience..... its the second time im asking.

just really curious.. but the frank show isnt that much waiting time!

@Random Hero:

the tonal characteristics ?

did you ever hear black label society live (zakk wylde) ????
this is THE sound, straight in your face and so great mids. just pure power....

 

[scottph]

I like my EL34's just fine...

Anyhow, isn't the 6550 supposed to be loud as hell? Might make a difference for the peeps playing at home mainly....

Practically they are not any louder just more clean headroom and hence you can use your amp louder without the tone changing much due to power tube distortion. 6550 tubes actually work very well with lover volume settings.

...and 6550 used by Diezel are Svetlana Tubes???

 

[scottph]

Thanks for clarifying! I thought the 6550 needed more volume to sound "good"...

Not true at all. We use SED 6550 tubes in all our amps now.

I know that as I talked to Peter S. on the cell about it, but I am pretty certain he mentioned them being "louder".

Not sure I agree with the term louder....may be a language thing. I will say they have more headroom. Either way, regardless og language or definition of terms, they sound great for multiple music styles, provide wonderful clean, dirty and in between tones, last a long time and have held up the best under out testing of all tubes. You can't go wrong with them.

 

[Joeytpg]

man the tube business is fucked..... too many unreliable tubes.

I still am a 6L6 guy. So far the KT77 in my VH4 sounded sweet, specially the gain. The cleans where very very nice too, but when the amp had 6L6 the cleans where just stellar!

Every Diezel amp now comes with SED 6550 tubes installed stock? Wow, I didn't realize that. Interesting!

I just got another Einstein and I'm thinking about putting a quad of Tung-Sol Reissue 6550s in it that I have sitting here unused.

Do it! External bias makes exteremely easy, I really want to try 6550's in my Herbert, but a sextet of them costs $200

The bad thing about 6550's is that your retube price just doubled compared to 34's and 6L6's.

I was going to put a set of 6550s in the VH4 this time until I saw the pricing on them

Screw 6550s!

I've got a set of SED 6550's that I was going to retube the Marshall Superbass with. Was gonna try them in the VH4, but haven't gotten around to it yet. I am a 34 kind of guy though. Plate voltage is quite a bit higher for the 6550's. Hope we don't start dumping transformers!

I will probably leave it as it is for a while. We have 5 weekends in a row of gigs starting this weekend, with the exception of the 16th. We are flying to London to see AC/DC and get down into some serious pub-crawling and work on a hydraulic diet .

[duesentrieb]

Bias them (480V/35 Watts/62.5%) to 45mA per tube, Chris.

 

[Random Hero]

I think I'll try some 6550s. Very curious.
