6L6/5881 is the cathode output stage in this 300B amp. This stage can reduce internal resistance and help to improve the frequency range of the tube amplifier.

Hi!

I'm looking for a tube amplifier which costs 350-500$
I am going to power a pair of CSS EL70 in Mar-Kel70 cabinet. I am listening to very mixed music. Some day i listen to Volbeat, Meshuggah and other heavy metal groups and some days i listen to Norah Jones, Joe Bonamassa or Andy McKee.

Do you have anything interesting?

Edit: I will have the signal XOed at 80hz (around 80hz) for this amplifier. I got another amplifier powering the subs. And the filter i Reckhorn S-1. So i don't need any realy performance below 80hz.

Hello,

Recommend EL34/KT66 class A single end amplifier:
http://www.diyaudio.com/forums/twin-...amplifier.html

It is output 7W and can drive CSS EL70 full range well.

If you like more powerful tube amp, can consider this 12W 6V6 push pull amplifier:
6V6 push pull integrated amplifier

The above amps are 220V AC input. If you really buy, I will offer 15% discount on the selling prices.

Thanks,
Tony.

Well, i think i want a little more watts. Closer to 20.
I want to play loud, that's true. And i don't know how far i will get with 7 or 12 watts.
And to be honest i didn't really like the aesthetics. Looked cheap somehow. Looked like thin aluminum (or some other metal) and those stickers with the text looked even cheaper.

I actually care a little about asthetics. I got a Harman Kardon HK3490 at the moment which is über-sexy. And i would like it in black, to match the HK.

Anything else that would fit?

Hi Rullknuffs,

you really don't need that amount of watt's – I think 10 W is plenty for most people. Depending on the speakers, music and the listening room of course. As a metal fan myself, I'm pretty satisfied with 6 W amp and speakers with 93 dB sensitivity (4.5'' Fostex driver).

I would go for EL34-based amp, as it would be most suitable for different music genre's.

Cheers | Kristian

Well, i don't know the sensitivity of my speakers. My room is like 3.7x4m.
And i want to play louder than i can at the moment (it's because i have no HP-filter yet).

Hello,

How about EL34 push pull at 35W output power?

Seems like a better choice...
Makes it possible to try other speakers aswell on it.

But just a tip... Skip those stickers. It looks like a toy. And that oldish orange lamp next to the switch?

I might be a little fussy about the aesthetics but it's quite important i think. The black "boxes" behind the tubes look better though. Are they metal?
And maybe all-aluminum volume knob and that would be better? Atleast i think so :S

Is it possible to get a cover or something for it. My brother has a cat and am about to get a little cousin the comings months...

The black "boxes" are the covers of output transformers. They are metal.
There is no cover for the amplifer.

Thanks.
