Tube pre-amp for gainclone amp??

JazzzSpazzz · 9th April 2012, 03:31 AM

Hi all,

My son is interested in making an amplifier to go with speakers that we have built. He wants to have a tube amplifier (because they look cool!), but I am thinking that a gainclone with a tube pre-amp would fit the bill. While he is interested in building audio things, I know from past experience that spending months investigating and experimenting will kill the project.

I have built lots of speakers & a couple of gainclones and kinda understand them, but do not even pretend to understand tube amps. I am looking for a straight forward way of having some fun building an amp with my son. I am interested in any DIY kit, DIY diagram/parts list, or even a Chinese pre-built from eBay, if it will work.

Anyone have some good links or know how to pull this off easily??

Thanks,
Bret

tube pre-amps could work well on gain clones.. here's a link for you DIY 12AU7 Tube preamp. the circuit is simple and easy to build... just a caution unlike gain-clones, tube projects work on very high voltages, so be careful...

I am sure there are some 12v Tube Pre's around.Have you looked on ebay?

Here's one - might be rubbish

Tube 6N3 Buffer Audio Preamplifier Pre AMP Kit For DIY | eBay

Here's another

Thanks!

I saw many of those on ebay. While I like to 12V aspect, I am also concerned about the quality of the design...if the components are legit...etc.

Anyone have any experience with these things??

Thnaks,
Bret

Thanks!

I really like the clean design & boards! The voltage is a bit of a concern for me, but it is do-able.

Thanks again,
Bret

Have a look at

Oatley Electronics

They have a couple of simple valve preamp variations to look at.

Depending on budget, you could also look at

They have a support forum here at Diyaudio.

Well....my son doesn't like the 'sub-miniature" tubes.

They don't meet the "visual" aspect of the project!

Oh, well.....
