Hi Thomas,
Which tube amplifier design of yours would suit driving 15ohms Rogers LS3/5a's? As you may be aware some EL34 or 84 pushpull designs (Leak or Radford) have been very popular partner for the LS3/5a.
Please advise or PM regarding your suggestions.
Thanks,
Dan
Dear Dan,
Depends on what music you listen. For vocals and light music, I believe 300B single end can well match with LS3/5A. For orchestra and pop music, EL34 push pull can handle LS3/5A well.
We can custom-make tube amplifiers with 15 ohms output transformers particluarly for your speakers.
Thanks.
Tony.
We have made some 300B amplifiers which are class A single end circuits. We can design our own circuits and make the amplifiers with parts we selected.
This is the 6SN7-300B amp made and sold in 2008.

Some vintage caps, Western Electric AZ-Cap oil capacitors and Cornell Dubilier were used in the 300B amp.

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-audio/167244-new-el34-6ca7-kt66-integrated-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:
http://www.diyaudio.com/forums/twin-audio/166542-6v6-push-pull-integrated-amplifier.html
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.

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...
