Default TU-8200DX Feedback

Elekit TU-8200 DX Headphone/Speaker Amp Review
jamespineapple replied to this thread on July 17, 11:26 am
Hello fellow TU-8200 owners
!

I wanted to chime in at Victor’s recommendation with my experience building this amplifier.

As I live in Vancouver, Victor suggested I visit his home to check out the kit before I purchased it. He was so helpful in explaining the process and even gave me a few additional upgrade components! We spent plenty of time at his place rolling through some different tubes as well – I got to listen to some Tung-Sol 5881s, PSVane KT88s, and even the holy grail RCA 6L6GCs. The RCAs blew me away with bass extension and treble clarity – they sounded perfectly flat, very smooth, very responsive. I felt a bit like I had gone back in time. It was an incredible experience.

I was originally planning to use a set of Winged C 6L6GCs in my build, but after the comparison at Victors place I knew I had to go another way.

The kit came together quite easily – Instructions were easy to follow and I had the whole thing assembled after about 8 hours of work. I’ve spent the past 3 weeks burning it in and it sounds better every day!

The tubes I ended up settling on in my amp are a pair of PhilipsEGC 6L6GCs and a pair of RCA cleartop 12AU7s. I find the Philips a little thicker sounding than Victor’s RCAs, but very similar in terms of bass extension, midrange detail, and responsiveness. The brightness of the cleartops seems to balance them out and adds a little bit of clarity and tightness to the equation. I tried some Sylvania 12AU7As as well as the Shuguangs that come with, and found that both sets tended to double up the low-mids from the power tubes. With the Winged Cs, which reminded me of Victor’s Tung-Sol 5881s in their mid-forward response, the Sylvania preamp tubes were a fair compliment but overall I liked the Philips/RCA combination better.

The only downside is that I had to pull my Philips tubes from my guitar amp, a vintage Magnatone 460, which sounds nice with the Winged Cs but some of that magic warmth is gone.

I’ve been using my TU-8200 in pentode operation, primarily with my Technics 1300 through a Boozhound Labs Phono pre that I also built. Speakers are yet to come for me, as I’m in a tiny Vancouver apartment! I have a set of AKG K702s that make me happy – as someone with a background in audio engineering I prefer a more clinical sound, and as someone who is more into jazz I also appreciate the mellow bass response so many people dislike about these cans.

I have to commend and thank Victor again for all his help! I was blown away by his hospitality and his suggestions really helped me with the build.

Default Elekit 8200 and 8500

Hey, this is my first post so be gentle...I'm a DIY kit junkie, I built some Dynaco stuff back in the late 70's after a tour in the Navy...can't believe I gave away some of that stuff but kept my A25's...Well I've built the Elekit 8200 amp and 8500 pre-amp...these are awesome kits..both fired up with no issues at all...I really love the ability to roll the tubes, really fun...I built a set of Fostex 206en in bass reflex cabinets (I'm no carpenter) but these things really kick, when I compare to the A25's well there is no comparison the Fostex are far superior to my ear...I'm thinking of my next project..what about a horn enclosure or should I just be fat dumb and happy with what I have...LOL..Thanks!

Hey Victor, sure wish I had a reason to build some more Elekiits, but these units are so great and durable, they are such a pleasure to build and have taken my system to another level...Thanks..Tom
