best amp for rock n roll

[sub_arctor]

good day

as a newbie, i am investigating the web for two month,
looking for informations about tubes after listening a wonderful one of my friend's 300B se amp.


i m right now decided to build a amp
with some requirements:

- i want to listen mainly rock, reggae, soul, pop, a bit of classic and a bit of blues

- DHT (my first experience as a tube listener)
- 8 or 9 watt of power (i want also to build more efficients speakers (93-95 dB) than mine
a maximum budget of 1100 euros


- i would like to know your own experience about tube and their technology

my main choice is 300B SE but is it a viable choice (specially for bass)???
and you?


- i red some threads about converting mono psu to power psu, about the power supply, i thought that just doubling the current was enough (and improving the filtering)? i would appreciate every suggestion about that

Thank you

Hi Julien,
maybe a 300b as first attempt is not an easy thing? (depends on your skills).
Have you listen some other topologies, tubes ? (thinking about bass...)

For me, more efficients speakers are allways better. (especially for little power tube amps)

Sinon, je comprends pas ta dernière question !? pour le prix ca devrait etre faisable, mais, as-tu les outils ?

PP has better bass. But I say build what you want, including the links posted here. It's the speakers you should bother about.

SET fans tend to be full-range fans. But there's nothing that says you have to use FR with a SET. For the 7-8W 300B you should go 96db or higher. 93db may very well be enough. But I wouldn't settle for less than 96.

I hope to build one of those as soon as I can get my hands on the new board.

I figure the end results to be more fool proof and of a quality that will make for years of enjoyment.

These are similar to my tastes although I sometimes get the urge to torture my neighbors with something like Depeche Mode. I have built dozens of tube amps in the past few years, most of them were single ended. Until recently my favorite rock amp was a push pull amp that used 300B tubes. I set out to design the SimpleSE with the goals of capturing the sound quality of a good 300B amp without the cost, and I wanted wall shaking bass like my push pull amp has.

I found that the bass capabilities of a SE amp depend mostly on the output transformers. To get big bass you need big transformers. I am using Hammond 1628SEA's for a 10 watt amp. You can get similar sized (12 pounds, 5.5 KG) in Europe.

Two people have recommended my SimpleSE amp. I have an obviously biased opinion, but this amp rocks! You are still going to need a pair of big SE output transformers.

Work and family commitments have slowed my progress somewhat (out of town again this weekend) but most of the assembly manual is done, and will be posted to the web site in a few weeks.

It is a reasonably foolproof design to build. I have already built 4 complete amplifiers, and a 5th is in the works. This is all being documented for the manual. I will have PC boards available for this amp in a few weeks. Some die hard DIY builders have already hand wired thier amps.

Put me on the list for 2 boards!

I thought about wiring one up by hand, But one look at the board and I was sold!

Very nice layout, Nice and compact, And parts that can be found easily and will actually fit right not to mention the flexibility in tube and transformer choices!!

Well done Indeed!

I would like to order a board for Simple SE. Where can I order these.

I will put an online ordering page on my web site as soon as the assembly manual is complete. With my current work schedule (10+ hour days) that should be a few weeks.

Trout:
It sounds really cool when fed with my ADA guitar preamp. I am working on a guitar amp that uses this board (both channels in parallel) as well as a few other applications.


I will put everything on the web site when it is done. I have been spending all of my free time finishing the SimpleSE manual (and the TubelabSE manual). When this is done, I want to get away from my computer for a long time. I sit at a computer all day at work, and now most every evening too. All of the fun stuff, like amp building and extreme testing is done. This means that I should have time for all of the cool tube projects that have been on hold for the last 2 months (long list).
