That statement makes me wonder what the context was of the conversation. IMHO, the 6528 is one of the better sounding output tubes that you can use with an Extreme that has been modified to accept them-especially for low impedance cans.

Happy Listening!

The 6528 requires 2x the heater current of the 5998. If you use the 6528 .... your amp will go up in smoke.

The 6528 is a nice sounding tube that sounds much like any of the other regulator tubes used as power tubes = more neutral, clean and solid state like. The 6528, IMO, does need a delayed/ soft start power supply that doesnt hit the tube with the full B+ at turn on .... or the tube wil die quickly.

Well, you are the expert! Thanks for the info. I have never tried it, so I can't say whether it sounds good or not.

But for the reasons you indicate above, I *definitely* wouldn't try it in a DV337.

 

[Mazuki]

The 6528 in the 337? Shouldn't be a problem, as long as you don't leave it on overnight. I can't say they sound dramatically better than other 6AS7 equivalents, but it certainly does make the music very punchy.

Sorry! so do u guys think that i should bid the pair n try them on my DV337,i'm really afraid that my 337 will smoke out.Pls advise.thks!

 

[Skylab]

I think what Mazuki said, and he is far more knowledgeable about tube circuits than I, kind of says it all. It will work, but it is likely a strain in the amp to the point where he doesn't think you should leave it on with 6528's running for a long time.

And then there are the other points - many 6528's may fail. The amp wasn't designed for them. They cost MORE than 6AS7G's or 5998's, which sound great in the 337, and there isn't any reason to think that the 6528's will sound better.

So - why do it?????

Your 337 won't smoke out.

As Skylab said, don't do it. For the money, it's better to stick with 5998s or if you ever see them, 7236s.

Here's another way to look at it. A 6528 is essentially two 5998s wired in parallel. So why not try one 5998 before trying two?

If you can't hear the difference between a 5998 and a 6AS7, then you probably won't hear it with the 6528.

Also, check out this meet in Chengdu, China. This is the same city that Darkvoice is located.

I'm actually rather surprised that the 337SE doesn't have the counter-bored volume knobs that the regular 337 does.

Some advice on this tube: I've got a small homemade amp which uses one E88CC (6922) as input and one 6080 as output. Should I use one of those 6528 in it ?
I'd be curious to see how it sounds (

) but I wouldn't want to burn down the amp or input tube, nor to do away with this tube which was lent from someone.

 

[djork]

based on the tolerances stuff on the previous page, i don't think u should try since the current requirements are quite high. i guess, settle for a 6AS7G or something.

 

[djork]

Anyone used 6SL7 tubes?

I assume you mean for the power tubes? You cannot use them as the driver tubes.

I know Mazuki used 6SN7's as the power tubes once. Worked fine - but with a LOT less gain.

Thanks for the link Mazuki. Any comments there about any improvements of the 337SE or the 3322 over their stock versions ?

 

[Mazuki]

The two main differences between the 337 and 337SE are the input tubes and the output coupling capacitors.

You can adapt the EF80 to the 6SJ7 easily and would not require opening the case. The output coupling caps is another story, I suggest leaving that alone unless you want seriously mod your amp.
