DIY Kits - Which for Cornwall III's??

Recommended Posts

My friend that owns an audio shop hads a customer who sold off her deceased husbands stereo gear, and included in the mix were boxes and boxes of DIY Kits that had been purchased, but never put together. I had some experience building Bottlehead, Tubes4hifi, jdslabs, & Elekit units in the past, so he asked if I could take it all home and help get it all built for him and he would allow me to have a few of the items. After days of digging through all the boxes, I pieced together all the kits (some of them I have already built):

 

- 6 DiyAudio Amp Camp Kits (Finished 4 of 6)

- 2 Hypex NC400 mono blocks (Finished)

-Aikido All in One Preamp 

- 2 Decware Zkit SE84's

- Elekit tu-8500 Preamp w/ Amtram upgrades (Finished)

-Elekit tu-8340 EL34/KT88 tube amp w/ Lundahl Transformers & Amtram resistor upgrades

- Bottlehead Eros, BeePree Special Edition, & Kaiju Special Edition (already built the Eros)

-2 DiyAudio Passlabs F-4 Amp Clones

-1 DiyAudio Passlabs F-6 Amp Clone

 

My main question is, which would be the best kit to keep for myself to experience with my Cornwall III's? 

 

I currently have a Bob Latino VTA-120 and the SP-12 Preamp from Tubes4hifi that I built. I am leaning towards the Bottleheads (300b's would be fun), the Elekit tu-8340 & 8500, or one of each of the Nelson Pass clones.

 

Thanks.

Can't answer you "main question" but have one of my own.  Any idea on the cost, if available, of the NC400s?

After research on them, you can only find them on European websites. They equaled out to about $650 per mono block amp after conversion before shipping.

So in light of that, which is about all the same as when I looked a while ago, what's the cost of those?

Heck, if you're building all of them, it only seems right to run them in and make sure they are 100% before giving them back to your friend. That will also give you a chance to demo them in your system. I have experience with Bottlehead, and that would be the first thing I would try. I've ready good things about the Elekit and the Amp Camp amp, so they would each get some demo time. There's probably not a bad choice in the bunch, but at least one should hit the sweet spot. Keep us posted, I'm very curious which ones you like the best.

The First Watt clones (F4 & F6) are highly desired (not so much the ACA). The caveat is that certain parts need to be authentic.

I'd pick the F4s.

Just a quick update on what I decided to keep for my Cornwall IIIs. I ended up building an F4, F6, M2x, and about to build an F5. Upon listening to the first 3, I thought the m2x sounded the best with my tube preamp, especially in the mids. The F6 was very detailed but not as punchy as the M2x. The F4 was the most detailed of all, but I did not have a preamp to fully test it.

 

The Akido all in one has given my VTA SP-12 preamp a run for its money! A sleeper DIY tube preamp IMHO.
